8 General Information Safety Information The Televic Wired Confidea Digital Conference & Interpretation System is state of the art and has been designed to meet quality. Nevertheless, the individual components of the conference system can cause danger for persons and material assets if the conference system is not used as intended, the conference system is set up by personnel not familiar with the safety regulations, the conference system is converted or altered incorrectly, the safety instructions are not observed. 8

9 Wired Confidea the digital conference & Interpretation system Overview If you require high-quality conference and interpretation equipment to support the communication process, then the Wired Confidea Digital Conference & Interpretation System is the solution to your problem. The new Wired Confidea Digital Conference & Interpretation System exploits all the advantages of digital communications technology and offers its users a series of important features: decentralized, clear sound reproduction, a full Digital System, easy installation and total control, functional and extremely easy to operate delegate units, audience interaction, advanced functionality, the possibility to be combined with an infrared Language Distribution System. The Wired Confidea Digital Conference & Interpretation System is the perfect choice for both small seminars and large international conferences. An important feature of the Wired Confidea Digital Conference & Interpretation System is its modular design. Even when you change from a configuration for small conferences to a larger configuration, you can easily add additional conference units and a software control program. Whatever the circumstances may be, the system can: 9

10 quickly be set up, since all conference units are connected in series, easily be configured for any kind of room and any kind of participants. 10

11 The components of the Wired Confidea Conference & Interpretation System A Wired Confidea Digital Conference & Interpretation System basic setup consists of the following components: delegate units, interpreter units, a central unit, system cables, and if required, the software control suite for the conference system. 11

12 The delegate units The delegate units feature a built-in loudspeaker, allowing the participant to directly hear all audio information, e.g. speeches, presentations or any other audio material. This loudspeaker system ensures excellent sound quality at a comfortable volume throughout the entire conference room. The delegate unit s electret microphone transmits every word in excellent audio quality over the system. The red signal ring on the microphone serves as an indicator of who is currently occupying the floor (when the red light is on). In configurations with voting units, the conference participants can participate in voting sessions. The delegate units can range from the most basic units to delegate units intended for a chairman with options like voting, interpreter channel selection and an Oled display. All the different delegate units will be presented in the next chapter. The units are connected in series. One cable string can comprise up to 20 conference units. The 6 ports at the back of the central unit can each connect a string of delegate units. Up to 120 delegate units can thus be connected to one central unit. And up to 1024 delegate units can be set up through coupled central units. All the different delegate units will be presented in the next chapter. Use of TCS2500 delegate units and flushmount combipanels in combination with Wired Confidea units The TCS2500 delegate/chairman units and flushmount combipanels can be used with Confidea CU. Remark : It is NOT allowed to connect devices with automatic input/output detection (like Wired Confidea delegate units) and other devices without automatic input/output detection ( like TCS2500 delegate units or flushmount combipanels ) in the same branche! 12

13 The units are connected in series. One cable string can comprise up to 20 conference units. The 6 ports at the back of the central unit can each connect a string of delegate units. Up to 120 delegate units can thus be connected to one central unit. And up to 1024 delegate units can be set up through coupled central units. The interpreter unit The interpreter unit has a similar design as a delegate unit. Next to the quality microphone and the headphone output it has three knobs for adjusting the volume, treble and bass levels of the incoming speech. The badge can contain all relevant information for each interpreter so that each interpreter can transfer his settings to a new interpreter unit. An extended amount of functionality is made available on the interpreter unit by the easy to use interface knobs and buttons and the LCD display. Every aspect of this functionality will be explained in the next chapter. 13

14 F1 F2 F3 ENTER The CONFIDEA CU The CONFIDEA CU is the core of the Wired Confidea Digital Conference & Interpretation System and, at the same time, serves as an interface for additional audio systems. During the conference, the central unit will manage the speech of the delegate units and the interpreter units. Via the central unit s operating menu, the configuration of the conference system can be altered to satisfy the needs of the conference room and its users. On the central unit, you can choose between 10 different conference modes, each with its own specific characteristics. However, some of these operating modes are only relevant in a system with the PC control software. The central unit manages the microphones, allows the operating mode to be set, activates the microphone units and manages the request-to-speak list. The central unit has a built-in power supply unit for powering up to 120 delegate and/or interpreter units and is therefore more than sufficient to set up a basic conference system. For larger conference systems, additional central units can be interconnected. The system cables Power supply of the conference and interpreter units is via the system cables which also transmit the digital audio and status information. 14

15 The software control suite (optional) A conference manager can control the entire conference via a PC if he uses the optional software control suite. The software control suite provides several extra functions, next to the functionality provided by the central unit: Additional functions for microphone management: the conference manager can easily monitor which delegates have made a request to speak, which delegates are currently speaking, activate certain microphones, etc. Two possibilities to manage the microphones are supplied: the first is a schematic view of the room and the delegates; the second is through a list of names (nominative view). Display of voting results as diagrams: the results of a voting can be represented graphically and can, for example, be displayed in the conference room by using a projector. Voting in combination with badge verification is also possible. Interpreter management: the conference manager can configure each desk in each booth. Configuration includes assignment of languages to interpreter units (both for the A and B channel), operation modes, etc. Delegate database: the delegate database allows the conference manager to specify delegate information. This information can then be displayed in the nominative and the schematic view of the microphone management screens. It is also possible to use the information contained on the badges. Multiple Chairmen units: the conference manager can assign multiple chairmen units. The technology used Both the control and sound transmission of the Wired Confidea Digital Conference & Interpretation System are digital, resulting in excellent quality. The language channels are transmitted over a 16 khz bandwidth at a 16-bit resolution. The delegate units are connected to each other and to the central unit by means of system cables. The system uses one digital speaker channel and a simultaneous translation of 4/8/28 channels. 15

16 The components of the Wired Confidea Conference & Interpretation System The components The components described on the following pages are available for the Wired Confidea Digital Conference & Interpretation System. Which of these components you require depends on the desired size of the Wired Confidea Digital Conference & Interpretation System. The Wired Confidea ( Confidea-L) delegate units 6 different delegate and 4 chairman units are available for the Wired Confidea Digital Conference & Interpretation System. All versions of the delegate units are equipped with varying levels of functionality. There is also one type of interpreter unit available. The delegate units differ from each other in the following features: a priority button for the chairman versions of the delegate units. An Oled display for channel selection and listening level indication, and two digital / buttons for language selection. 5 or 3 voting buttons. an Oled display for voting related information or other relevant information. These features are only available on certain delegate units. We will present and explain each of these delegate units. Next to the delegate units the interpreter unit will also be presented and explained. 16

A complete technical overview of the settings of the serial communication ports COM1, COM2 and COM3: Bits per second: Data bits: 8 Parity: None Stop bits: 1 Flow control: None The CONFIDEA CU is able to serve conference systems in a non-coupled environment with up to 120 units. For larger systems with a maximum of 1024 terminals, you can interconnect up to 40 central units via the system cables. The CONFIDEA CU is an integration of a microphone system and an interpreter system. The CONFIDEA CU s menu control allows you to: set the conference system to one of the 10 different operating modes (note however that some are only relevant in an environment where there is a PC connected to the central unit with the microphone management software), set the delegate unit s audio options like volume, automatic gain reduction, low, middle and treble, configure the options of the microphone system and the interpreter system, initialize the microphone and interpreter system, specify the auxiliary IN/OUT settings, reset the microphone and interpreter system, configure the language options of the interpreter desks and booths, save the configuration for the interpreter system as Config1 or as Config2, 22

23 load the configuration for the interpreter system from Config1 or from Config2, and more. Via the two XLR-3F sockets (AUDIO IN 1 & 2) of the central unit you can connect microphones with suitable preamplifiers or you can feed audio signals from additional audio equipment to the conference system. The output signal of the floor speech is available on the XLR-3M audio output (AUDIO OUT). Via the XLR- 3M audio output you can: connect a public address system and transmit the audio signal of the floor speech via the public address system, transmit the audio signal of the floor as original soundtrack to a broadcasting station. It is also possible to connect an infrared language distribution system to the CONFIDEA CU, allowing guests or participants who don t have their own conference unit to follow the conference via infrared headphones. The guests or participants can also choose between the floor channel and up to 28 additional language channels. You can also connect an analog output panel (AOP) to the CONFIDEA CU. The purpose of the analog output panel is to provide the system with additional analog outputs. A total of 9 XLR-3M ports are available to send an analog signal out to other devices, for example, a recording device or a public address system. A D-sub connector with 6 analog outputs is also present on the central unit for analog outputs. The technical specification of the connector is explained further in this manual under Connecting equipment to the AUX OUT. 23

24 CONFIDEA CU license options Conference options Camera Control / Control Panel If you have a license for Camera control/control panel you will be able to communicate with a camera control system or a control panel. More information about the supported functionality can be found in appendix A and B, Interpreter license The interpreter license indicates the maximum number of interpreter channels allowed. The available number of maximum channels is: - 4 channels (standard license) - 8 channels - 28 channels 24

This means that an auxiliary device like a tape recorder could be controlled through this contact. 7. CINCH analog output 8. XLR-3F analog output 25

26 1 2 Repeater for the system (*) A repeater is used to strengthen the signal on a system cable. When a system cable reaches a length of 80 m, the signal over the system cables becomes too weak. We can insert a repeater after the lengthy system cable to strengthen this signal. The repeater box has two ports, the IN and OUT port. The RJ-45 OUT connector (1) should connect a cable string with a delegate unit and the CONFIDEA CU should be connected to the RJ-45 IN connector (2) of the repeater. The power supply (DC) which reaches the repeater is 60 VDC straight from the central unit. It is also allowed to attach a string of delegate units to the CONFIDEA CU and then when a system cable between two delegate units reaches 80 m to insert a repeater. As you can see, the coloring of the RJ-45 ports on the repeater is similar to the coloring of the RJ-45 ports of the delegate units. This makes connecting it to delegate units quite straightforward. (*) Important Remark : Repeaters are devices without automatic input/output detection, so may NOT be used in branches where devices, with automatic input/output detection (like Confidea-L units), are used! 26

27 The LEDs of the repeater: The repeater box has, next to the two RJ-45 connectors, three LEDs: LINK FAIL: lights up when there is no communication with a delegate unit. LINK FAIL: lights up when there is no communication from the CONFIDEA CU. POWER SPLY: should always lights up, whenever the repeater has power. 27

28 The system cables The system cables required for the planned conference system are included in the delivery if they were ordered. These cables have RJ-45 shielded connectors. The length of the system cables may range between 0.5 m and 80m. With these cables, you can: interconnect the delegate units, interconnect up to 40 central units for setting up large conference systems, interconnect with an analog output panel. Via the system cables you can connect the cable strings with the delegate units to the CONFIDEA CU.

29 Structuring the Wired Confidea Digital Conference & Interpretation System Expansion stages This chapter provides information about possible conference room configurations. It will be explained by using some example set-ups on how your conference system can be structured. The components which are required for the different expansion stages will also be discussed. Finally, this chapter also gives an overview of the additional audio equipment that can be connected to the conference system. Possible expansion stages Depending on the number of conference participants, four different expansion stages are distinguished as examples. These expansion stages will show you some possible set-ups of the Wired Confidea Digital Conference & Interpretation System. It is possible to set up a diverse set of configurations depending on the requirements of the user and the conference room. These expansion stages should help you tackle any problems while setting up a configuration. Expansion stage (1) comprising up to 20 terminals Expansion stage (2) comprising up to 120 terminals with various kinds of terminals Expansion stage (3) comprising up to 600 terminals In all the configurations, the conference terminals are interconnected and powered via the system cables 29

30 which also transmit the digital audio and status information. Note: In the following examples, the standard length of 3m is always given for the system cables between the conference terminals. However, it is not a problem to use other cable lengths or cables of differing length within the same string of delegate units. To make sure that all the delegate and interpretation units are supplied with a sufficient voltage level, please refer to the chapter Determining the maximum cable lengths. Expansion stage (1): up to 20 conference terminals In small conference system configurations (expansion stage 1), you can start with 20 conference terminals connected to one CONFIDEA CU. Note: The number chosen here: 20 is only a sample number, the real number of terminals depends on the requirements of the user and the conference room. Example 1: The maximum distance between the central unit and the first conference terminal or two conference terminals may not exceed 80 m without a repeater. Normally the length of the system cables between two conference terminals is typically 2 or 3 m. If you interconnect the maximum number of conference terminals in one string, the length between the central unit and the first conference terminal may not exceed 80 m without a repeater. In the discussion of the expansion stages and the examples, we will use a length of maximum 80 m for the first system cable. 30

31 F1 F2 F3 ENTER 6 F1 F 2 F 3 ENT ER EXI T 25 m Note: Next to these requirements the total length of the cable string which connects all the terminals to the central unit should not exceed a specific length. This length can easily be calculated for your desired configuration. We can provide you with a power calculator tool that can be used to simplify the calculation of this length. Up to 20 conference terminals can be interconnected in one string. All 20 terminals can be powered via the CONFIDEA CU s integrated power supply unit. 80 m 3 m 3 m m Instead of interconnecting 20 terminals in one string you can also split up the terminals into three different strings: Example 2: The CONFIDEA CU s integrated power supply can power up to 120 terminal units which can be split up into six different strings. In our expansion stage we only have 20 terminal units which we will split up into four different strings. Each of these strings will have 5 terminal units attached to it. The distance between the CONFIDEA CU and the first conference terminal of a string may vary, but the maximum distance of 80m without a repeater may not be exceeded. The length of the system cables between two terminals is typically 2 or 3m. 3 m 3 m 3 m 3 m m 3 m 3 m 3 m 3 m 10 m m 3 m 3 m 3 m 80 m m 3 m 3 m 3 m

32 F 1 F 2 F3 ENTER <=80 m Expansion stage (2): up to 120 terminals with various kinds of terminals In conference system of expansion stage (2), up to 120 terminals can be connected to the CONFIDEA CU. Example: The maximum distance between the CONFIDEA CU and the first terminal may not exceed 80m without a repeater. The distance between the conference terminals is typically 2 or 3m. Since the CONFIDEA CU s integrated power supply can only supply power for a maximum of 120 conference terminals, it is discouraged to attach more conference terminals. When you do decide to attach more than 120 terminals to a central unit, then a correct operation of the system cannot be guaranteed. 3 m 3 m m 3 m... <=80 m <=80 m <=80 m 3 m 3 m <=80 m 3 m 3 m <=80 m 3 m 3 m m 3 m Expansion stage (3): up to 600 terminals with various kinds of terminals You can connect a maximum of six cable strings with up to 120 terminals to one CONFIDEA CU. For larger systems with up to 1024 terminals, you therefore require a total of nine CONFIDEA CUs. One of these central units is master. The additional CONFIDEA CUs are connected as slaves to the central unit configured as master. In an environment where the microphone and conference system is controlled by a PC, the PC must be connected to the master central unit. In this expansion stage a total of four CONFIDEA CUs are needed to control all the microphone and interpreter 32

A maximum of 20 terminals can be interconnected in one string, and a total of six strings can be attached to the central unit. After interconnecting all the strings and attaching all the strings to the appropriate CONFIDEA CU we can begin to interconnect the central units. How the central units are interconnected is described in the topic Interconnecting multiple central units. The distance between a CONFIDEA CU and the first conference terminal of a cable string may not exceed 80m without a repeater. The length of the cables to interconnecting the central units should be kept as short as possible and certainly not exceed 80m. 3 m 3 m... <=80 m m 3 m... 3 m m 3 m 3 m m 3 m 3 m... RS232 <=15m 5 <=80 m m 3 m

34 Determining maximum cable lengths In the preceding examples, the standard length of 3 m is always given for the system cables between the conference terminals. However it is no problem to use cables of different lengths within the same string. If you want to use longer cables, make sure that all the conference and interpreter terminals including the last one in the string are supplied with a voltage of at least 30V! Calculating the voltage drop on the system cables Every meter of cable and every conference terminal in a string causes a voltage drop. Thus the further back a conference unit is located in a string, the less voltage it receives. We have constructed a power calculation tool to automate the calculation of the lengths of these strings. The sheet is an easy method to calculate the voltage drops on the individual sections of a sting. This way, you know before setting up the conference and interpreter system whether the system will function correctly or not. 34

External audio sources are, for example: PORT 4 PORT 3 PORT 2 PORT 1 DATA SLAVE SLAVE MASTER OUT OUT IN OUT wired microphones, wireless microphones, the audio channel of a video, a CD player, etc. Transmitting a channel to broadcasting and TV stations Important conferences and specialist congresses are of great interest to the public. The Wired Confidea Digital Conference & Interpretation System therefore allows you to either transmit the floor speech via the XLR-3M or SUB-D audio output (AUDIO OUT 1). On the AUDIO OUT you can output up to five interpreter channels/speeches of your choice. With an AOP2500 Analog Output Panel system you can output more channels for recording or broadcasting via the additional XLR-3M ports on the AOP2500. Transmitting a channel to a Public Address system Via the central unit s (or the AOP2500) XLR-3M audio output, you can connect a PA system to which the floor speech/channel can be transmitted. This public address system can then broadcast the sound in e.g. the foyer or another room. 35

36 Transmitting a channel via an infrared transmission link You can connect the control of an infrared transmitter, allowing guests or participants who don t have their own conference terminal to participate in the conference via infrared headphones. These guests or participants can then choose between the floor speech/channel and the interpretation channels. 36

37 Setting up the conference system Installing and interconnecting This chapter provides information on how to set up the Wired Confidea Digital Conference & Interpretation System.

Interconnecting the conference units The conference units are interconnected via the RJ-45 shielded connectors on the back of the conference units. The IN connector is colored grey and the out connector is colored black. The system cables have a grey and a black connector to guide you during the interconnection of the terminals. Free Input/Output connectivity in a specific branche is only possible when only Wired Confidea units (= Confidea-L) are used in that branch. When TCS2500 delegate or flushmount combipanels are used in the same branch as Confidea-L units, then Input/output connectivity of TCS2500 and Combipanels must still be respected! Connecting a cable string to the central unit After having interconnected the conference units, you have to connect these strings to the CONFIDEA CU. You can connect up to six cable strings to one central unit. Connect the cable string to one of the RJ-45 shielded connector sockets labeled: PORT 1, 2, 3, 4, 5 or 6. 0 I When the length of the cable to the first conference unit, or when the length of the cable between conference units is 80m; then a repeater should be placed between the central unit and that delegate unit or between the two delegate units. To see additional information about the repeater and how to connect the repeater to the central unit and a delegate unit and/or between two delegate units see the paragraph on: Repeater for the system. 38

In the chain topology we interconnect the CONFIDEA CUs via the RJ-45 shielded connector sockets (SLAVE IN, SLAVE OUT and MASTER OUT) at their rear. The CONFIDEA CU which is master has an FTP-CAT5 cable connected to the MASTER OUT port. The SLAVE IN and SLAVE OUT ports are then used for the central units which are slave. 0 I At the first CONFIDEA CU, connect the end of the system cable to the MASTER OUT socket. This central unit is now master. 0 I Connect the other end of the system cable (coming from the master unit) to the SLAVE IN socket of a second CONFIDEA CU. For multiple slaves, connect the SLAVE OUT from the first slave to the SLAVE IN from the next slave. 0 I Configure the slave central units so that the master-slave symbol ( ) is displayed on the main menu item. Please refer to the explanation for the main screen for more details on this symbol. Star topology When the conference room has a high number of coupled central units, it might be better to use a star topology. In this topology we interconnect the slave 39

40 CONFIDEA CUs via the RJ-45 shielded connector sockets (SLAVE IN) at their rear with the master central unit via the connector sockets (MASTER OUT, SLAVE OUT or PORT 1-6) or with a slave central unit via the connector sockets (MASTER OUT, SLAVE OUT or PORT 1-6). The CONFIDEA CU which is master has an FTP-CAT5 cable connected to the MASTER OUT port or/and a cable connected to PORT 1-6 or SLAVE OUT. The SLAVE IN port are then used for the central units which are slave. If necessary the MASTER OUT, SLAVE OUT port or PORT 1-6 of the slave central units can also be used to further extend the star topology At the first CONFIDEA CU, connect the end of the system cable to the MASTER OUT, SLAVE OUT or PORT 1-6 socket. The central unit will be master as long as no cable is inserted in the SLAVE IN port of the central unit. Connect the other end of the system cables (coming from the master unit) to the SLAVE IN socket of the slave CONFIDEA CUs. For large star topologies, connect a system cable between the SLAVE IN port of a central unit and a SLAVE OUT, MASTER OUT or PORT 1-6 of another slave central unit Configure the slave central units so that the master-slave symbol ( ) is displayed on the main menu item. Please refer to the explanation for the main screen for more details on this symbol. General Briefly: A CONFIDEA CU is able to go into slave mode if the master-slave symbol is visual ( ). A slave CONFIDEA CU is identified by a connection on its SLAVE IN port and the slave symbol ( ). If the SLAVE IN port is not connected then it is automatically a master central unit ( ). The output port that connects with the SLAVE IN port can be the SLAVE OUT or the MASTER OUT port or one of the 6 digital bus ports. Typically the MASTER OUT and the SLAVE OUT will be used for coupling, but in an alternative configuration you can use them to add extra conference units with an external power supply. The startup sequence of the central units is randomly. Do keep in mind that the startup of the central units, in a 40

41 coupled environment, can take a considerable amount of time. All the units connected to all central units in the configuration have to be processed. The central unit will react slower to user input during this phase. Once the system is fully initialized, everything will react normally. This initialization time is dependent on your configuration. The basic principle applied here is: the larger the configuration, the longer the initialization time. The CONFIDEA CU which is master can be used to configure all settings. The other CONFIDEA CUs which are slave are locked and will display the locking symbol ( ) in the lower right corner of the screen of the CONFIDEA CU. You cannot alter any settings on a slave central unit. Go back to master mode, by pressing the F2 button for 3 seconds, if any settings need to be altered. 41

First, use the level control to reduce the headphone volume to the minimum. Slowly set the volume to a medium level. When people use headphones, they tend to choose a higher volume than with loudspeakers. Listening at high volume levels for long periods can lead to permanent hearing deficiency. Please protect your hearing! Connecting the analog output panel You can connect an analog output panel (AOP2500) to the central unit for audio output. The DATA OUT socket on the CONFIDEA CU should be connected to the DIGITAL IN socket of the AOP2500. Connecting an external audio source AUX OUT / CONTROL AUX OUT 1 AUX IN 2 AUX IN 1 You can connect external audio sources such as wired microphones, wireless microphone systems, the audio channel of a video recorder, a CD player, another conference unit for remote conferencing, etc. to the conference system. The audio sources to be connected must deliver a balanced mono signal at the XLR-3F socket (8). Depending on the strength of the audio signal, you can increase the input sensitivity of the conference system in the central unit s operating menu. 8 Connect the audio sources as follows: PORT 4 PORT 3 15 (c) PORT 2 PORT 1 DATA SLAVE SLAVE MASTER OUT OUT IN OUT Connect the audio source to one of the XLR-3F sockets of the central unit. If necessary, adapt the input sensitivity in the operating menu. 42

43 Connecting equipment to the AUX OUT Please refer to the pin assignment illustration below of the Sub-D 15 connector. The connector is of the following type: Sub-D 15 Female UNC thread AUX OUT 6 AUX OUT 5 AUX OUT 4 AUX OUT 3 AUX OUT 2 AUX OUT 1 AUX OUT pin assignment PIN SIGNAL 1 Aux out 1 (XLR AUX OUT) 2 Aux out 2 3 Aux out 3 4 Aux out 4 5 Aux out 5 6 Aux out 6 - headphone jack 7 Control Out 8 Control In (Max 5V) 9 GND, AUX out 1 10 GND, AUX out 2 11 GND, AUX out 3 12 GND, AUX out 4 13 GND, AUX out 5 14 GND, AUX out 6 15 (c) The aux out numbers described in the above illustration relate to aux out in the menu of the CONFIDEA CU. For example: if you change the channel assigned to aux out 3 on the central unit, then these changes will be noticed on the 3-11 pin combination. The floor speech/ channel signal is transmitted on aux out 1. This channel cannot be changed. The floor speech/channel signal is also transmitted on the XLR- 43

44 3M socket. The volume difference between AUX OUT 1 on the SUB-D 15 connector and the AUX OUT 1 on the XLR socket can be adjusted by changing the Volume XLR in the AUX OUT 1 menu item. By default there is no difference. It is however possible to alter the channel signal for the remaining auxiliary outputs. You may assign any interpreter channel or the floor channel to these outputs. Next to the channel you can alter the volume and the status (ON/OFF) of an auxiliary output. The volume difference between AUX OUT 6 on the SUB-D 15 connector and the AUX OUT on the headphone jack can be adjusted by changing the Vol. Headphone in the AUX OUT 6 menu item. By default there is no difference. Connecting the PC to the central unit The PC software consists out of two different parts. The two distinguishable parts are the microphone management software (TMS2500) and the interpreter management software (TIS2500). To connect the PC to the CONFIDEA CU, when you installed both the microphone and interpreter management software, you need two serial ports on your PC. One serial port is necessary for the conference management software and the other port is necessary for the interpreter management software. The COM ports of the central unit work at a speed of bits per second. The port on the back of the CONFIDEA CU labeled COM 1 is the port associated with the interpreter management system (TIS2500). The port on the back of the CONFIDEA CU labeled COM 3 is the port associated with the microphone management system (TMS2500). Note that the software versions will be checked at both sides before starting the communication. The PC will check if the CU version is compatible with the PC software version and the central unit will check if remote control is allowed by the pc that asks the connection. 44

45 The cables necessary to connect the central unit to the PC are described below. The diagram of the cable described above is actually a null-modem cable. This means that a standard nullmodem cable without handschaking can be used to connect the PC with the central unit, Remark : NO hardware handshaking is allowed (check comport settings)! 45

46 Turning the central unit on and off When turning on the power of the conference and interpretation system, it is important that the components are turned on in the correct order. In conference systems with several central units, first turn on the master central unit. Then turn on the slave units in the sequence they are connected to the master unit. Please keep in mind that it takes a certain amount of time until the system has fully started up. The larger the configuration, the longer it takes to start the system. During this phase, the menu will react slower to user input. Once all units are initialized and the system has started up, the master central unit will react normally again. Turning the central unit on 22 T 3.15 A L ( 230 V) T 7 A L ( 115 V) 0 I V A 50 / 60 Hz WARNING ELECTRICAL HAZARD. AUTHORIZED PERSONNEL ONLY. Set the POWER switch (22) in the ON position. The conference and interpretation units which are connected to the central unit are now ready for operation. The start display appears on the LCD display of the central unit. Volume = P1 P2 P3 P4 P5 P6 Figure 2 - The start-up screen of the central unit Turning the central unit off Set the POWER switch (22) in the OFF position. The conference and interpretation units are now disconnected from the voltage supply. Switch off the central units in a coupled configuration starting with the slaves. Finally switch off the master central unit. 46

47 Configuring the conference system Overview This chapter provides instructions on how to: operate the Wired Confidea operating menu, initialize the microphone system, set the operating microphone mode, adjust the audio settings for the loudspeaker, activate and configure the auxiliary inputs and outputs, resetting the microphone system, access the microphone options, configure the interpreter system, choose the language options for the different booths. 47

48 Introduction to the CONFIDEA CU s operating menu The startup display After turning on the central unit, the start display appears, showing the Wired Confidea Digital Conference & Interpretation System main menu where you can choose between six menu choices: Conference: contains the configuration of the microphone system and the delegate units. Interpreter: contains the configuration of the interpreter system and the interpreter booths. AUX-OUT/IN: contains the configuration of the auxiliary outputs and inputs. System: contains system wide configuration options Language: contains the language configuration of the CONFIDEA CU s menu. License: contains all license related information and configuration options. After approximately one minute the menu will jump to the volume setting of the delegate loudspeaker. This happens because the volume setting is accessed most frequently when using the Wired Confidea Digital Conference & Interpretation System. The lock functionality It is possible to lock the menu of the central unit. Suppose that you configured the central unit to your desires and you do not want anyone to alter these settings. To do this, you have to lock the main screen of the central unit. This is the screen where you can see the volume bar. Navigate to the main menu of the central unit. The menu can now be locked by pressing the F1 and the F3 button at the same time and keep them pushed for about two seconds. After you released the buttons the locking symbol ( ) will be displayed in the lower right corner of the screen of the central unit. When you try to access the menu of the central unit by pressing the ENTER button, nothing will happen. This means that you are successfully locked out of the menu. The menu can be unlocked again by the operator whenever he wants to alter some settings. The sequence to unlock the menu is the same as the sequence to lock 48

49 the menu. Press the F1 and the F3 button at the same time again for about two seconds to unlock the menu. When the buttons are released the locking symbol ( ) will disappear from the lower right corner of the main menu. Note: The locking symbol also appears on certain central units in a coupled environment. Specifically, they appear on the slave central units. You can distinguish a slave central unit from a locked central unit by the volume bar. A slave central unit has no volume bar. The menu buttons The wheel, ENTER and button allow you to navigate through the operating menu.

77 The menu - explained Working with the root menu Volume = P1 P2 P3 P4 P5 P6 Volume = P1 P2 P3 P4 P5 P6 P 1 P 2 P3 P 4 P 5 P6 The main screen The main screen contains two important elements. The first is a volume bar which can be altered using the wheel. During a conference the volume can be set lower or higher when necessary. The second element is an indication of the ports. These indicate which ports are used and to which port a string of conference terminals is connected. More of this is explained in the section discussing the system diagnostics. Two central units can also be coupled to establish a bigger conference room, controlled by a single, the master, central unit. More on this coupling can be found elsewhere in this manual. To indicate that a central unit is able to work as a slave central unit a sign has been put in the top right corner on the menu display. If this symbol is not visible, try to press the F2 for about 3 seconds. If the symbol doesn t appear, it means you have a restricted license. When the symbol is visible and the central unit has detected a master central unit on the slave port, the central unit will automatically go into slave mode, the slave symbol will be adjusted like shown in the picture on the left. In summary the table below explains the slave symbol. (NO SYMBOL) Central unit is in master mode, but can not go into slave mode due to a user setting or due to a restricted license Central unit in master mode, but can go into slave mode when connected to a master central unit Central unit in slave mode 77

78 78 When a central unit is in slave mode, but some settings need to be altered like the output channels on the different analog outputs, you can always go back to the master mode by again pressing the F2 button for about 3 seconds.

79 The conference menu - overview Default values of the microphone system 1 Conference A number of default values will be loaded into the System the first time the CONFIDEA CU boots. These default values ensure a correct operation of the CONFIDEA CU conference system. However, all delegate units connected to the central unit will display an Init Refused screen. This means the delegate units are not known to the conference system. We should therefore start with the initialization of the microphone system. NOTE : an overview of the default values can be found in appendix D Conference 7 Initialise Units Initialise Units 2 Automatic Init Manual Init 1 Full Init Full Init Press ENTER to Save Initializing the microphone system The first time you start using the Wired Confidea Digital Conference & Interpretation System in a new set-up you have to begin with an initialization. The initialization can take place in two different ways. You have the choice between an automatic initialization and a manual initialization. Both options have their advantages and disadvantages, which we will pinpoint in a moment. The automatic initialization is very useful when you want to initialize the conference units without initializing each conference unit separately. When you enter the automatic initialization menu, then the conference units will have initialized themselves. You will be informed to wait a little. After pressing the ENTER button the units will be initialized. If the order in which the conference units are initialized is important, then you are advised to use the manual init. When the manual initialization is active, then the red signal ring of all the conference units will begin to flash. Notice that only the delegate units will begin to flash and not the interpreter units! The interpreter units do not respond to an initialization of the conference menu because these are managed by the interpreter subsystem. Pressing the microphone button on the conference units will signal the central unit that the 79

80 Manual Init 2 Add Unit Manual Init 3 Delete Unit Delete Unit Micro Number = 0000 Press ENTER to Del. Manual Init 4 Reserve Unit Reserve Unit Micro Number = 0000 Press ENTER to Res. microphone is initialized. If the microphone is accepted by the central unit, then the red signal ring will stop flashing. You can now initialize the conference units in the order you desire. In case you already have a room configuration set up which you want to keep, and you want to add a new unit, then you can opt for the Add Unit menu item. When the menu item is activated, then the red signal ring of all unknown conference units start to flash. The new units may now be initialized by pressing the microphone button. In case you want to delete a conference unit from the configuration, you have to select the microphone number on the central unit in the Delete Unit menu item. Once you have selected the appropriate number and pressed the ENTER button, then you can safely remove the conference unit. In case you want to reserve a conference unit you have to select the microphone number on the central unit in the Reserve Unit menu item. Reserving a microphone is useful when you have a room in expansion. Maybe some place to put e.g. microphone 17 is foreseen in the future but cannot be set up right now. In this case you can reserve the microphone for later. The sequence in which a microphone is reserved is somewhat special though. To reserve a microphone, you should first enter the Manual Init Full Init menu item. Start the full init and exit the menu item. Then browse to the Reserve Unit menu item and enter the numbers of the conference units you want to reserve. After these unit numbers have been entered, you can start pushing the microphone numbers of the conference units. Suppose now that you reserved conference unit number 7 and you have come at a moment when you want to add conference unit 7 to the configuration. The first thing you have to do know is activate the Delete Unit menu item to delete the reserved number from the conference configuration. Once the unit number has been deleted, you have to activate the Add Unit menu item, and press the newly added conference unit. It will have been initialized with the previously reserved number. Note: When you enter the Manual Init Full Init menu item, then all data about previously reserved numbers will be lost. 80

81 Choosing the conference mode By selecting a certain conference mode, you can strongly influence the character of a discussion: you can determine the level of control of the chairman, and you can determine whether the conference participants can take the floor immediately or if they have to apply for the floor. Note: A chairman unit is always able to speak! No matter what mode the conference system is in, the chairman is always able to speak by pressing his MICRO button. The chairman can also deactivate all active conference units by pressing his PRIOR button or activate the delegate unit that requested to speak by pressing the NEXT button. Note: Multiple chairmen units can also be assigned by using the PC software or by using appropriate menu item. Conference 1 Operating Mode Operating Mode Direct Access Press ENTER to Save You have the choice between 10 different operating modes. The operating mode is selected in the Operating Mode menu item. Note however that one mode is only useful in combination with a PC installed with the software control suite. This mode is: No request. Without a PC you can use the With request, With request no clear, Direct Access, FIFO, Group 1-4 and override. With a PC and the software control suite all the operating modes can be used. Operating modes: No request: the participant willing to speak has to notify the conference manager that he is willing to speak. He can do this by raising his hand or any other means not involving the microphone. Once the conference manager has noticed that a participant has requested the floor, he can activate microphone of the participant or ignore his request. The conference operator has total control over the microphones. With request: enables the participant to send a request to the chairman or conference operator by pressing the microphone button (or to cancel his request by pressing the microphone button again). Once the floor is requested, the green LED above the microphone button will flash. This means that the conference unit is in request mode. The 81

82 chairman or conference operator grants the participant the permission to talk by using the NEXT button or by clicking the green microphone on the computer screen. While the conference unit is in request, the red signal ring of the microphone will flash if this option is selected. With request no clear: enables the participant to send a request to the conference operator. However, he cannot cancel his request. The chairman or conference operator grants the participant the permission to talk by using the NEXT button or by clicking the green microphone on the computer screen. During the in request period, the red signal ring of the microphone will flash if this option is selected. Direct Access: enables the participant to turn on his microphone at any time. The only limitation here is the maximum number of microphones which may be active simultaneously. FIFO: enables one microphone at a time to be active without intervention of the conference operator. Activation of a new microphone overrides the current active microphone. The only exception here is that the microphones of a delegate and the chairman can be active at the same time. Group 1: enables one microphone at a time to be active without a request for activation. Other participants may put their microphone in request mode; the first applicant gets the floor when the delegate who has the floor turns off his active microphone or when the chairman or conference operator grants the participant the permission to talk by using the NEXT button or by clicking the green microphone on the computer screen. Group 2: enables two microphones to be active at the same time. Other participants may put their microphone in request mode; the first applicant who requested the floor gets the floor when one of the currently active microphones is turned off or when the chairman or conference operator grants the participant the permission to talk. Group 3: works exactly like Group 1 and Group 2, with the alteration that three participants can have the floor at the same time. Group 4: works exactly like Group 1 and Group 2, with the alteration that four participants can have the floor at the same time. 82

83 Override: works like the FIFO mode, with the alteration that MAX # Microphones participants can have the floor at the same time. Activation of a new microphone will overrides the microphone that was active for the longest time if the total number of active microphones would exceed the user defined MAX # Microphones. Here we have also the exception that Chairmen units can always be activated. Conference 2 Microphone Limit Conference 3 Loudspeaker Max number of microphones simultaneously active In the operating mode No request, With request, With request No Clear and Direct Access the maximum number of microphones which may be active is relevant. This number can be set in the Microphone Limit menu item. The range of this value is between 1 and 15. Adjusting the audio settings for the loudspeaker By selecting the Loudspeaker menu item you can alter the audio settings of the conference unit s loudspeakers. It is possible to adjust the volume, the low, the middle and the treble audio settings. The volume can also be adjusted when the menu jumps back to main menu. Turning the wheel button will automatically change the volume. If you choose to save the settings, then these settings will be stored in the central unit so that the next time the system boots these settings will become active automatically. 83

84 Conference 4 Microphones Adjusting the audio settings for the microphone By selecting the Microphones menu item you can alter the audio settings of the conference unit s microphone. It is possible to adjust the automatic gain reduction, the low, the middle and the treble audio settings. The limiter gain of the microphone can also be set. Turning the wheel button will automatically change the audio setting. The automatic gain reduction indicates how much the gain will be reduced when multiple microphones become active. The higher the number, the higher the reduction will be for multiple microphones. If you choose to save the settings, then these settings will be stored in the central unit so that the next time the system boots these settings will become active automatically. The following graphic shows the automatic gain reduction in function of the number of microphones that are activated. The gain reduction is indicated in decibel and referenced to the gain for one active microphone. Each graph indicates an automatic gain reduction number that can be set on the central unit. Note that although the maximum number of microphones is 15, the curves stop at 9. When more than 9 microphones are activated the gain reduction will be kept constant. gain reduction (db) Automatic gain reduction # active microphones

85 It is possible to adjust the limiter gain curve for the microphones by setting the desired offset value in db. This is especially used to determine the reach for the microphones. So it is possible to exclude the noise in a room from amplifying. In a room with much noise only the speakers voice will be amplified and not the noise. Lowering the limiter gain will result in a shorter reach, otherwise stated: only the sound of sources close to the microphone will be amplified. 0dB limiter gain -18dB limiter gain Conference 5 Chairmen Configuring the chairmen Multiple chairmen units can be assigned in the Chairmen menu item. By default, during initialization, only one chairman unit will be assigned. One can assign up to 50 chairmen units for a single conference configuration. The picture below shows how to assign multiple chairmen units: Chairmen ENTER Set Chairmen ENTER Set Chairmen 1 Set Chairmen 01 = 0000 ENTER 01 = Press ENTER to Save By entering the Set Chairmen menu item, a chairman index number can be selected. Note that the first two digits are marked. The first two digits represent the chairmen index number in the range from 1 to 50 because 50 chairmen units can be assigned. We start with the first one so we scroll to number 1 by using the wheel button. After the correct index number has been reached, press the ENTER button. 85

86 Note that after hitting the ENTER button the right four digits are marked, These digits indicate the delegate unit that will be configured as chairman. In this example we want to select delegate with number 3 as chairman so we scroll to number 3 by using the wheel button. Next, to confirm the settings press the ENTER button again. The delegate with number 3 is now configured as a chairman unit. Note that now the index number is marked again, making it possible to assign another chairman unit. If more chairmen units are desired, repeat the same steps but now with a different chairmen index number. Clear Chairmen Configuration will be overwritten. Continue? The chairmen list can be cleared by entering the Clear Chairmen menu item and hitting the ENTER button. NOTE 1: When the conference room is controlled by a PC, the local chairmen settings will be overwritten by the PC settings. NOTE 2: When the delegate units are reinitialized, the chairman settings are cleared. Conference 7 Reset Conference 8 Options Resetting the microphone system If for any reason the system has to be reset, you can do this in the Reset menu item. Only the microphone system will shut down and start up again immediately. This will not affect the interpreter system. Accessing the microphone options The microphone options are the Options menu item. The menu item contains a number of menu items which allows the conference system to be checked and to adjust some general settings. Two test modes can check the sound of the delegate loudspeakers and can check which microphones are connected to and initialized by the CONFIDEA CU. The Test Tone is used to generate a test tone on all loudspeakers of all delegate units. The Test Units option will activate the micro of all delegate units one by one in the sequence they were initialized. Once the test 86

87 Light Ring Blink at Request Press ENTER to Save sequence reaches the last unit, it will automatically restart the test. The Test Tone comes in useful when you are testing the loudspeakers of the delegate units. Activate the Test Tone option whenever you are not sure that the loudspeaker of a delegate unit is working correctly. The Test Units option is useful when you initialized the delegate units and you want to test if there were all initialized correctly. The delegate units will only activate when they are known to the system. The third item in the Options menu allows you to set the behavior of the red signal ring on a delegate unit during request. You can choose to let the signal ring blink along with the green request led or you can choose to only let the green request led blink on the unit in request. 87

88 The conference menu - example Suppose the following circumstances apply: a Wired Confidea Digital Conference & Interpretation System needs to be set up in a conference room in which a meeting with 10 participants will occur. One of these participants is a chairman and the participants will have to vote during the conference. We will need up to 10 conference units for our system of which one conference unit is a chairman unit. To be able to configure this configuration we would need for instance the following hardware: one CONFIDEA CU, one Confidea_L CV and nine Confidea-L DV units. Let s start setting up the system starting from a default configuration. The setup will be described one step at a time to make it easier to understand. If you feel that the discussion of the setup is too detailed, feel free to skip this section. The starting point of the steps that needs to be taken is the main screen of the central unit unless noted otherwise. Loading the default settings Start by loading the default setting for the conference desks. We start from the main menu. Press ENTER, choose Conference. Press ENTER again, now choose Initialize units. Press ENTER. Now choose Load Defaults, press ENTER. Press ENTER again to load the default values. To go back to the main menu, repeatedly press the button until you reach the main menu. Now that the default values have been loaded; we need to reboot the system. Start from the main menu again. Press ENTER, choose Conference. Press ENTER again, now choose Reset. Press ENTER again to reset the conference system. Now go back to the main menu. Select the operating mode We want to select our mode of operation. The differences between the different modes of operation are explained above. Press ENTER, choose Conference. Press ENTER again, now choose Operating Mode and press 88

89 ENTER. Select the operating mode and press ENTER to save the operating mode. Changing the delegate loudspeaker settings The audio settings of the delegate loudspeaker can be changed if for instance the volume settings of the delegate loudspeakers are too low. The volume setting of the loudspeakers of the conference units can easily be changed in the main menu by turning the wheel. The setting isn t saved however. If you want to save the setting you must go through the following sequence of steps. Press ENTER, choose Conference. Press ENTER again, now choose Loudspeaker. Press ENTER and choose Volume. Press ENTER and turn the wheel to set the volume to the desired value. Press ENTER to save the adjusted volume level. If you want to change the Low, Middle or Treble settings, go through the same sequence as described above and select the Low, Treble or Middle menu option. Save your settings and exit the menu. Changing the delegate microphone settings The audio settings of the delegate microphone can be changed if for instance the gain is to high when multiple microphones are activated. The automatic gain reduction setting of the conference units can be changed by following the next sequence of steps. Press ENTER, choose Conference. Press ENTER again, now choose Microphones. Press ENTER and choose Auto Gain Redu.. Press ENTER and turn the wheel to set the gain reduction to the desired value. Press ENTER to save the adjusted gain reduction level. If you want to change the Low, Middle or Treble settings, go through the same sequence as described above and select the Low, Treble or Middle menu option. Save your settings and exit the menu. Changing the maximum number of microphones which may be active simultaneously Press ENTER, choose Conference. Press ENTER again, now choose Microphone Limit. Press ENTER. Turn the 89

90 wheel to alter the maximum number of microphones. Press ENTER to save your settings. Initializing the conference units There are 2 options during the initialization, an automatic and a manual initialization. In most of the cases an automatic initialization will suffice. The manual initialization is most handy when you want the delegate units numbered in a desired sequence. The automatic initialization is self-explanatory; to initiate it, execute the following sequence. Press ENTER, choose Conference. Press ENTER again, now choose Initialize Units. Press ENTER, choose Automatic Init. Press ENTER. Wait until the menu displays Press ENTER to save initialization, then press ENTER. The manual init consists out of four parts. We have a Full Init, an Add Unit, a Reserve Unit and a Delete Unit menu choice. The purpose of these menu choices has been explained above. The steps which need to be taken are similar to the example given below. To manually initialize the conference units execute the following sequence: Press ENTER, choose Conference. Press ENTER again, now choose Initialize Units. Press ENTER, choose Manual Init. Press ENTER and choose Full Init. Press ENTER. The red signal rings of the conference units will start flashing. Press the MICRO button of the conference units in any sequence you desire. After pressing the MICRO button the red signal ring stops flashing, this means that the conference unit is initialized. Go back to the CONFIDEA CU and press the ENTER button to save the configuration. Congratulations, the system has been initialized. To add a conference unit, execute the Add Unit menu option. The red signal ring of the new conference units will start flashing. Press its MICRO button to initialize it. When you want to delete a conference unit from the current configuration execute the Delete Unit menu option. 90

91 Select the number of the microphone you want to delete. Press ENTER to delete the microphone. The Reserve Unit menu option has been explained above as well as the steps to take. Let the red signal ring blink in request mode To let the red signal ring blink along with the green request led above the microphone button follow the next procedure. Press ENTER, choose Conference. Press ENTER again, now choose Options. Press ENTER and choose Light Ring. Press ENTER and turn the wheel to set the light ring in Blink at Request mode. Press ENTER to save this setting. Working with delegate conference units Talking: The most important button on a conference unit is the MICRO button. The MICRO button is used to speak or to issue a request-to-speak. When you have to request the floor to take the word, you need to press the MICRO button. The green LED above the MICRO button will then begin to flash along with the red signal ring if this option is chosen. The chairman unit or a conference manager which has a PC with the microphone management software installed is able to grant you access to the floor. Once you have been granted the floor the red signal ring will light up. Translations: To listen to the translated floor channel you must have a conference unit with a channel selector. To change the channel, press the up and down buttons above and below the channel selector. You will then hear the translation of the floor channel in your headset. Voting: You can only vote when the voting session has been started by the chairman. For this you need delegate units with voting possibility. Once the voting session has started, you will notice that you have a choice for your vote. These screens are depicted on the left. To vote press the button under the value of the vote you want to cast. The vote will then be registered. Once the voting session is over, the results will be shown on the display. 91

92 Working with chairman conference units Priority: The chairman unit works in the same way as the delegate unit, but has three extra options. The first extra option is the PRIOR button. The prior button can be used in two ways. It can be used to mute all currently active delegate microphones or is can be used to deactivate all of the active delegate microphones. All the active microphones of the delegates will be deactivated when you press the PRIOR button and release it quickly. Just tapping the PRIOR button will do just that. By keeping the PRIOR button pressed down, you can mute all active delegate microphones. When you release the PRIOR button, then all muted delegate microphones will become active again. All requests for the floor are ignored while all delegate microphones are muted. Once the PRIOR button is released, the conference can proceed again in its normal operation Voting: The second option is the possibility to start the voting. However, voting is only possible with units which have voting possibility. The display menu on the chairman s unit can be chosen by pressing the PLAY or STOP buttons. At startup the screen of the chairman unit looks like the figure depicted on the left. Note however that when the conference room is controlled with a PC the chairman units can no longer start a vote session as this can be done using the conference software. Next request: The third option is to grant a delegate unit access to the floor if he requested the floor to take the word. On the Confidea-L CD, CV and CIV the NEXT button is used to grant the floor to the first in request. 92

93 The interpreter menu - overview Next to the conferencing functionalities of the Wired Confidea Digital Conference & Interpretation System we have an interpreter system. The interpreter system works closely with the interpreter desk units (ID2500), so you have to have access to these units when you want to use the interpreter system. Usage We will explain how the interpreter system is used with an example. Let s suppose we are in a conference room where three different languages are spoken and where the participants of the conference do not understand a language different from their native tongue. The three spoken languages are English, French and German. Let us now suppose that six interpreters are at out disposal and that we have six interpreter units for the interpreters to use. The interpreter unit may be mixed with the normal conference units on a string or they may all be on the same string. The good way to set up the interpreter terminals is to divide them in three separate booths. Three booths are set up with, in each booth, two desks. We allow the interpreters to relieve each other by setting up two desks in a booth. The booth and desk number is configured on the interpreter desk (ID2500 unit) while you are in the initialization mode. The first booth is assigned to the English language, this means that its A channel is assigned to ENG. The second booth is assigned the French language, so its A channel is assigned to FRE and the third booth is assigned to the German language so its A channel will be GER. Next to the A channel there is also a B channel. The B channel of each booth and therefore each desk can have another language assigned to it. This language depends on the preferences of the interpreter as he can choose his desired language. If the interpreter knows more than one language, i.e. the interpreter understands ands speaks English, German and French; then he ll be able to translate to each of these languages. This means that even though the A 93

94 channel of a booth is fixed to a specific language, he will be able to translate to the other languages on the B channel. Interpretation 1 Configuration Configuration 1 New Configuration 2 Current Save Config. as Configuration 1 Press ENTER to Save Configuration The Configuration menu allows you to make a completely new configuration, alter the settings for the current configuration or load a previous made configuration. In the new and current menu you can select a booth and alter the settings for that booth. The settings that can be altered are the Language, the Autofloor and the B-channel. When you alter the settings of a booth you have to remember to save the settings for each booth. At the end of a configuration you can choose to save the interpretation configuration as Config1 or Config2. Not saving the settings or exit at the end leaves the current configuration unchanged even when you began a new configuration. New Configuration When you begin with a new configuration, by pressing the enter button, the previous settings in the interpreter system will be cleared. The settings for each booth can now be configured. NOTE: Don t forget to save the configuration as Config1 or Config2 after you altered and saved the settings for each booth. It is recommended to change the parameters in the option menu, if necessary, after you made and saved a new configuration. Current Configuration Entering the current menu you can make corrections on the current configuration without deleting the settings for each booth made previously. You will be able to adjust the settings like explained below. Saving Configuration After altering the language settings for each booth, starting from a new configuration or continuing with the current one you will be asked to save the configuration. You can choose to save it as Configuration 1 or Configuration 2. Not saving the configuration (or exit) brings the interpreter system in the same state as it was before you entered the configuration menu. 94

95 Configuration 3 Load Load Configuration 1 Press ENTER to Load Load Configuration A previously saved interpreter configuration can be loaded. You can choose from 2 independent configurations. After a load there will automatically be a reset which will reboot the interpreter system without affecting the conference system. Not only the language settings for each booth will be loaded but also the parameters in the option menu and the initialization settings that were made after you saved the configuration file. Although, you can alter these parameters and initialization settings after a load without affecting the language settings for all booths. In this case a reboot will be necessary. This can be done by activating the reboot in Reset menu item. Choosing the language options for the different booths Booth Configuration 1 Language A channel - Language Through the language setting we can change the A channel language of the booth. The A channel language is the language to which a booth is assigned. For example, when multiple languages are spoken during a conference and the French language is one of the spoken languages. Then you would add an interpreter booth which translates the French language to e.g. English and make the booth responsible for the English language. To do this you would set its A channel. Booth Configuration 2 B-Channel B channel The B-channel is the second language an interpreter understands and speaks fluently. For example, Bob is born in the U.K. and thus speaks English fluently. He has studied the French, Spanish and Italian languages which he understands and speaks fluently. He has been assigned to the booth responsible for the English language. During the conference English and French are spoken. Bob translates the floor language to English whenever French is spoken. Suppose now that Bob is also responsible for the translation from English to French. To translate to the French language Bob sets his B channel on the French language. In short: A translator may be responsible for multiple languages. To be able to translate to these languages the interpreter configures his interpreter desk accordingly. The A channel is thus the main language the interpreter 95

96 is responsible for (which cannot be changed from the interpreter desk) and the B channel is the second language an interpreter is responsible for (which can be changed from the interpreter desk). When you access the B-channel menu option you are presented with a numeric choice. These numbers represent the booths in the system. This option is important when you want a specific language on your B-channel after startup. Suppose you have three booths: booth one is English, booth two is French, booth three is German. For the third booth you want the B-channel to be set to English as a default setting. Then you set the B-channel to 1 during the configuration of the booth. Remember though that the B channel can be changed on the interpreter desk. Booth Configuration 3 Auto-floor Auto-floor Next to these settings the auto-floor option can be activated. The auto-floor setting concerns working with the B Channel on the interpreter unit. In circumstances where the original floor-language is well known or not so well known, two different operational procedures can be used. Under normal circumstances the original floor language is well known to all interpreters and they listen to the original floor speech for translation. The translations are then fed to the language distribution channels so that the conference participants can listen to them. In situations where interpreters are unfamiliar with the floor speech and are therefore unable to translate it, the system offers an automated relay interpretation facility (auto-floor). An interpreter assigned to translate the floor speech, translates it into another language easily understood by other interpreters. The floor language channel on all interpreter desks (except the floor language channel of the interpreter which translates the floor speech) will be replaced by this transfer interpretation. This transfer interpretation or auto-floor is then used as the base for any further translations. We have included two illustrations which explain the normal interpretation and the relay interpretation for a better understanding. The first illustration show how a normal interpretation works. Every interpreter translates the floor language. 96

97 Booth 1 Booth 2 Booth 3 Booth 4 Floor English Floor Russian German French English In the next illustration, Russian is the floor speech and the auto-floor facility is enabled for the Russian interpreter s desk. This interpreter selects outgoing channel B and automatically relays an English translation of the floor speech as auto-floor to all other interpreter desks. His translation is therefore fed to the English language distribution channel. The incoming channel AUTOFLOOR indicator is activated on all other interpreter desks to indicate that auto-floor is active. Booth 1 Booth 2 Booth 3 Booth 4 Floor Russian Floor Auto-Floor B A A A English German French English In short: Well, whenever an exotic (auto-floor) language is spoken on the floor, it is translated. And it is this translation of the floor speech that is used as a basis for translation. Notice that the floor channel for the 97

98 delegates will not change. Auto-floor only concerns the interpreter side of the system. Interpretation 2 Initialise Units Press Mic to confirm BOOTH DESK Initializing the interpreter system When the full initialization of the interpreter system is executed, all of the red signal rings of the interpreter units will start flashing. The screen depicted on the left will then appear on all interpreter desks. You will have to manually configure the booth and desk number on each interpreter unit. Press the MICRO button to send the configuration data to the central unit. You will notice that the other booths will have incremented their BOOTH / DESK value. This allows you to step through the initialization without much configuration. You can end the initialization at the central unit after you have initialized all interpreter desks end Once the initialization is done, the LCD displays of the interpreter units will show the different channels (A & B) and other information. If something went wrong during initialization then the interpreter units will display an init refused screen. When this happens you should try to reinitialize your booths. If this doesn t correct the problem check your booth configuration. When you traverse the Initialize Units menu you will notice that there is an Add Unit menu option. Suppose that we have an up and running system but you only have one interpreter desk in the second booth and you want to add another. You should then choose the Add Unit menu item. The red signal rings of the interpreter desks will now start flashing again and they will all show the initialization screen (which is depicted in the beginning of this section). You do not have to reconfigure the interpreter desks you already initialized previously. So go directly to the new interpreter unit. Configure the booth and desk number of the new interpreter unit and confirm your configuration. Rebooting the interpreter system (TIS) Interpretation 3 Reset It is good practice to reboot the interpreter system whenever you have made changes to your configuration at the central unit. Rebooting the interpreter system does not affect the conference system. This means that you can make changes to the interpreter system during a conference. 98

99 After loading a configuration from the configuration menu it may not be necessary to reboot as this will automatically follow after a load. However, if you choose to reinitialize the interpreter system it is recommended to reboot the system. You can execute a reboot in case the interpreter system needs a reboot by activating the reboot in Reset menu item. Interpretation 4 Options Booth Limit Max Booths = 04 Press ENTER to Save Desk Limit Max Desks = 3 Press ENTER to Save Options Within the options menu of the interpreter system you can alter the maximum number of booths, the maximum number of desks per booth, the operating mode between and within the booths. A total of 28 interpreter booths can be connected to the CONFIDEA CU and within each of these booths 8 desks can be placed. This means that up to 224 interpreter units can be used in a conference configuration. Maximum booths and desks The maximum number of booths stipulates the number of interpretation languages a conference system will support. For example suppose you have a conference room where English, French and German will be spoken. You even have two interpreters for each language. The only thing we have to do is configure the system to have three booths and two desks. The maximum number of desks defines the number of desks each booth has. For example, if you set the maximum number of desks to three, then this means that each booth may have up to three desks. Note: The number of interpreter languages supported by your CONFIDEA CU does also depend upon the licensing scheme you have bought. A standard system can configure 2 languages. Options 3 Mode between Booth Mode in and between booths In the mode between booths three choices are available. Mixed mode: more than one interpreter can translate to the same language. The audio signals of the translation are mixed and the interpreters are notified of this mixed audio signal by the flashing of their microphone indication led when they are translating simultaneously. For example, booth 1 is translating the floor language to French (on its A channel) and booth 2 starts to translate 99

100 Options 4 Mode in Booths to French (on its B channel). The delegates in the conference room will hear the two translations mixed through their headsets. The interpreters are notified of this mixed audio signal by the flashing of the microphone led and the red signal ring. Override: any interpreter microphone in another booth can override the current active microphone and become active. The interpreter microphone that was just overridden cannot return active again until the booth responsible for the override deactivates its microphone. Toggle Override: any interpreter microphone in another booth can override the current active microphone and become active. The interpreter microphone set to nonactive can return active for this translation by pressing his microphone button again. In the mode in booths only Mixed and Override is available. Mixed: multiple interpreters may simultaneously translate to the same language. Whenever two interpreters translate simultaneously they are notified by the flashing microphone led and the flashing red signal ring. Override: this is similar to the Override mode of the Mode between booths. The only difference here is that the override happens on a per booth basis. The interpreter menu - example Suppose we have the room configuration: a Wired Confidea Digital Conference & Interpretation System with a total of 2 languages spoken during a conference. We will need up to 2 booths and 2 desks per booth for dual interpreters to set up a correct configuration. You have to have an additional license to be able to configure more booths. This license can be purchased trough your sales agent. To be able to configure this we would need the following hardware: one CONFIDEA CU and six ID2500 interpreter desks. The number of conference units depends on the conference room. Let s start setting up this system starting from a default configuration. The setup will be described one step at a time to make it easier to understand. If you feel that the discussion of the setup is too detailed, feel free to skip this section. 100

101 Loading the default settings Start by loading the default settings for the interpreter desks. We start from the main menu. Press ENTER, choose Interpretation Press ENTER again, now choose Initialize Units. Press ENTER. Now choose Load Defaults, press ENTER. Press ENTER again to load the default values. Now that the defaults have to been loaded; we need to reboot the system. Start from the main menu again. Press ENTER, choose Interpretation. Press ENTER again, now choose Reset. Press ENTER. Press ENTER again to execute the reboot. The system has just been rebooted. If you go the interpreter desks and look at their screen, then you will notice that it will display Init Refused. Congratulations, this means that we have just rebooted our system to the default configuration. Configuring the booths Now that the system has been reset, we can start configuring the settings of the booths on the CONFIDEA CU. This has to be done before initializing the interpreter desks and before altering the general settings. Suppose we want to make our booths responsible for the following languages: booth 1 for English and booth 2 for Arabic. There are 2 possibilities to make the necessary changes. You can start from a new configuration or you can continue with the currently configuration. Because we started from the default configuration there will be no difference. Suppose we choose to continue with the current configuration. Start configuring each booth in the following sequence: Alter the settings for the first booth. Start from the main menu again. Press ENTER, choose Interpretation. Press ENTER again, now choose Configuration. Press ENTER. Scroll to Current and Press ENTER. Select the booth number 1 and press ENTER. Now we will alter the settings of booth 1. Turn the wheel and select Language. Now press ENTER. Select your new language by turning the wheel. Our choice for the language of booth 1 is English; so select ENG. Press ENTER to confirm the choice of our language. 101

102 NOTE: remember to press ENTER when you selected a language, otherwise the language chosen will not be confirmed. Save Booth Yes Press ENTER to Save Save Config. as Configuration 1 Press ENTER to Save You have just configured the new language for booth 1 in the CONFIDEA CU menu. These changes have not yet been saved however. To save these changes press. You should now go to the screen depicted on the left. Turn the wheel to select the Yes option and press ENTER to save. Our booth configuration has just been saved. Suppose we wanted to change the auto-floor and B- channel settings of our booth too. To do this, we would have changed their settings before saving. The B-channel may require some explanation though. The B-channel menu on the central unit displays numbers. These numbers reference the other booths. Suppose you want booth 1 to have Arabic as its default B channel. Arabic is the language of booth 2. We will configure booth 2 in a moment but suppose for know that booth 2 is configured correctly. To set Arabic as the default B- channel select B-channel = 2 and press ENTER. Now save the booth as we have just configured the settings. Configure booth 2 now by going through the steps just described above. Set its language correctly to Arabic ( ARA ) language. Configure its B-channel and Auto-floor settings as you wish. After you configured and saved the booths, you also need to save the global interpreter configuration as Configuration 1 or Configuration 2. This can be done by pressing the button in the Select Booth menu. You should now go to the screen depicted on the left. Turn the wheel to select the file you want and press ENTER to save. Our configuration has just been saved. Altering the settings of each booth Now that the booths has been correctly configured and the room configuration has been saved as configuration 1 or configuration 2 we can start altering the settings for each booth. The current default settings are the following: number of booths is 2, number of desks per booth is 2, mode between booths is Override and the mode in booths is Override. As these default settings will probably not match your needs, you can start changing these settings at this moment. It is important 102

103 to keep the correct order in the configuration procedure to prevent unexpected errors. In this case the number of booths and desk are the same as the default values so it is not necessary to change this. Configuring the interpreter units Now that we are done configuring the booth on the CONFIDEA CU, we will set up the interpreter desks so that they will receive their information correctly. First, reboot the system. You may even check your booth settings to see if they correspond to the configuration we have set up in Configuring the booths. If everything was done correctly you will see that these settings are correct. We are going to initialize the interpreter desks. Start from the main menu again. Press ENTER, choose Interpretation. Press ENTER again, now choose Initialize Units and press ENTER. We are now presented with a Full Init and an Add Unit. The full init is used when we start with a fresh system. The add option is used when you have a configured a system and you want to add a new booth or desk to you configuration. Enter the full init mode. Press ENTER. You will notice that the red signal rings of the interpreter desks will start flashing. This means that they are in initialization mode. Configure all the booths correctly. Once all booths have been set correctly, go back to the central unit. 01 ENG 02 ARA FLO FLO FLO FLO Ending the initialization mode at the central unit Back at the central unit. To stop the initialization phase, press the ENTER button. If everything went good you should see the screen depicted on the left on an interpreter desk or a variant of that screen depending on the booth and desk number of that interpreter desk. This screen tells you that the interpreter unit has been configured correctly. We can now start working with the interpreter desks. The Add init possibility Suppose that we have an up and running system as the one we just configured but you only have one interpreter desk in booth 2 for the moment and you want 103

104 to add an interpreter unit to this booth, so that it would have 2 desks. You should then choose the Add Unit menu item and press ENTER. The red signal rings of the interpreter desks will now start flashing again and they will all show the screen as depicted on the left. Ignore the interpreter desks you already initialized and go straight to the new interpreter unit. Set the booth of the interpreter unit to 2 and the desk to 2 and confirm by pressing the MICRO button. Now go back to the central unit and press the ENTER button. You will notice that the new interpreter desk has just been added to our configuration. Working with the interpreter units You can check the desk and booth number of an interpreter desks by pressing the MUTE button, keeping it pressed down and pressing the up or down MENU buttons a couple of times. You cannot alter the A channel of an interpreter desk at the interpreter desk. The A channel of a booth is fixed. However, you can change the B channel of an interpreter desk by keeping the B button at the right of the screen pressed down and pressing up or down simultaneously. This will cycle through all the available languages. This means that an interpreter can choose his own B channel. The loudspeaker channel can be changed by keeping the LS CHAN. button pressed down and pressing the up and down buttons simultaneously. Relay 1 can be changed by keeping the RELAY 1 button pressed down and pressing the up and down buttons simultaneously. Relay 2 can be changed by keeping the RELAY 2 button pressed down and pressing the up and down buttons simultaneously. Relay 3 can be changed by keeping the RELAY 3 button pressed down and pressing the up and down buttons simultaneously. The green LEDs at the right of the screen indicate which channel you have currently selected. An interpreter is currently translating the language of an A or B channel when the red LED at the right of the screen is lit. 104

105 The New function Like already mentioned, you can begin a new configuration by selecting the new menu. As soon as you enter the new menu the current configuration will be deleted. However, if you choose not to save the new configuration, the previous configuration will be restored. After you made a new configuration you can alter the maximum number of booths, the maximum number of desks per booth, the operating mode between and within the booths in the option menu. Suppose we use currently a configuration that is saved as Configuration 1 but we want to make another configuration without deleting Configuration 1. Immediately beginning with changing the options needed for Configuration 2 will change the options for Configuration 1 because after you altered the options a general save follows which affects the current configuration, in this case Configuration 1. To avoid this, start with making a new configuration and save it as Configuration 2. Afterwards, alter the necessary options. Now you have two working configurations that you can load at any time. 105

106 Auxiliary menu overview 3 Aux-In/Out Aux-In/Out 1 Aux Out 1 Aux Out 1 2 Volume XLR Aux Out 3 1 Volume Aux Out 3 2 Channel Usage The auxiliary menu is used to configure all inputs and outputs of the CONFIDEA CU. A number of external devices, like a CD player or a microphone with preamplifier, could be connected to the auxiliary input. Other devices, like a recording unit, could be connected to the auxiliary outputs. Also remote conferencing is possible between two conference rooms. The devices which will be connected to the central unit differ from configuration to configuration. Therefore the menu allows the auxiliary inputs and outputs to be configured as needed. The outputs The system has 6 auxiliary outputs. The configuration of the first auxiliary output, labeled AUX OUT 1 on the back of the CONFIDEA CU, differs from the other outputs as the channel of this auxiliary output is fixed. The channel of this output is the floor channel. The AUX OUT 1 is an XLR-3M output or the first output that is contained within the D-sub connector. The volume difference between AUX OUT 1 on the SUB-D connector and the AUX OUT 1 on the XLR socket can be adjusted by changing the VOLUME XLR in the AUX OUT 1 menu item. By default there is no difference. Also, it is possible to enable remote conferencing. This will be discussed later in this paragraph. The other outputs, AUX OUT , are contained within the D-sub connector. The pin assignment of this connector has been discussed above. Volume: The volume of the outputs can be configured to the correct level. Just enter the Volume menu item and set the appropriate level. The volume level will change as the wheel is being turned. However, if you want to save the settings so that the system always booths with a certain volume level on that port, then do not forget to press the ENTER button to save the new value. Channel: The audio signal of the interpretation channel which an auxiliary output should output is configured within the Channel menu item. The channels out of which can be chosen depend on the licensing scheme of 106

107 Aux Out 3 3 Status Aux Out 6 2 Vol. Headphone AUX-OUT/IN 7 Aux In 1 Aux In 1 1 Level Aux In 1 2 Sensitivity Aux In 1 3 Status your CONFIDEA CU. If you have a basic license, then you are able to choose two channels. Status: The status setting of the auxiliary output enables or disables the selected output. The headphone output channel on the front of the central unit is the same as AUX OUT 6. The volume difference between AUX OUT 6 on the SUB-D 15 connector and the AUX OUT on the headphone jack can be adjusted by changing the Vol. Headphone in the AUX OUT 6 menu item. By default there is no difference. The inputs The system has two auxiliary inputs. These inputs are labeled AUX IN 1 and AUX IN 2 at the back of the CONFIDEA CU. The two inputs are both XLR-3F connectors. Level: The level of the inputs can be configured to the correct level. Just enter the Level menu item and set the appropriate level. The audio level will change as the wheel is being turned. However, if you want to save the settings so that the system always booths with a certain volume level on that port, then do not forget to press the ENTER button to save the new value. Sensitivity: The sensitivity of the input channel can be altered through this menu option. The sensitivity setting has two options: LOW and HIGH. Status: The status of the auxiliary input enables or disables the selected input. 107

The illustration shows the connections that you should make. Room 1 AUX OUT 1 AUX IN1 Room 2 AUX OUT 1 AUX IN1 Aux Out 1 4 Remote Conf. AUX-OUT/IN 7 External Equalizer It is necessary to enable remote conferencing in the AUX OUT 1 menu in each conference room to avoid echoing. The screen you should go to is the screen depicted on the left. NOTE: keep in mind that for remote conferencing only AUX IN 1 and AUX OUT 1 can be used. External Equalizer To avoid disturbing feedback or to equalize the audio signals it is possible to interconnect external equipment to the central unit. When such external equipment is used, the external equalizer option should be set. When setting the status to ON, the audio floor channel will be 108

109 disrupted in a way that all input signals (except AUX IN 1) will be directly routed to the AUX OUT 1. The signal present on AUX IN 1 will be used as the new floor channel. This way it is possible to use external audio equipment like equalizers or feedback destroyers. The schematic picture below summarizes this feature. External Equalizer =OFF External Equalizer = ON Remark : (Re)Setting the status for the external equalizer to ON will change some other functions automatically: o AUX IN 1 status = ON o AUX IN 1 level = 18 (nominal) o AUX IN 1 sensitivity = HIGH (+12 db) o AUX OUT 1 status = ON o AUX OUT 1 volume = 18 (nominal) o Remote conferencing = OFF The settings can still be changed manually to desired values. 109

110 Auxiliary menu - example Recording or sending the audio signals of our translations to other devices Suppose now that you have some additional audio equipment installed which you will use to record translations or which are used to sent the audio signal of these translations to another device. For this you have to configure the auxiliary outputs. The Aux Out 1 audio signal is always the floor channel signal; you cannot change this. However, the Aux Out 2, Aux Out 3, Aux Out 4, Aux Out 5 and Aux Out 6 audio signal can be changed. We will explain how to set the (audio/interpreter) channel which should be sent to these outputs on the central unit. Start from the main menu, and press ENTER. Now choose Aux-In/Out and press ENTER. Select Aux Out 1 and press ENTER. You can change the volume and the status of the Aux Out 1 output signal. The volume choice is self-explanatory and the status menu has two options: On and Off. Set the status to On if you want to enable the signal sent out. The other output menu choices contain the same volume and status options. In addition to these options a channel option is also present. What does the channel stand for? Recall that we just configured our interpreter system as explained above. English is on channel (booth) 1 and Arabic on channel (booth) 2. The numbers describe the booths in our system. You can therefore set which audio signal you want to send to your output. 110

111 System menu overview Usage The system menu contains system wide monitoring and configuration options. Five different options are present: System 1 Diagnostics Port Errors P1 P2 P3 P4 P5 P6 System 2 Camera Control System 3 Control Panel Diagnostics An overview of the conference terminal strings connected to the central unit is provided in this menu. It is also what you ll see on the main screen (with the volume bar). Next to this overview you can also check if there are communications errors on specific ports from within the Port Errors menu item. The symbol representing the error will then appear on that port. Explanation of the symbols: : means that there is a string of conference terminals connected to the port described under the symbol. : is the opposite of the above symbol. It stands for an unconnected port or a wrongly connected string of conference terminals. (No string or a wrongly connected string of conference terminals is connected to that port number). In the case you have a string of conference terminals connected to the central unit and the symbol remains, then check if you have connected the IN port of the conference terminal to one of the six ports. : is the symbol representing the communications error. It will only appear on a port to which a string of conference terminals is connected as no communications errors can occur on an unconnected port. Pressing ENTER will reset the error indicator. Camera control If you ordered a Wired Confidea Digital Conference & Interpretation System with camera control, then this option is enabled through your licensing scheme. Otherwise you cannot alter the settings of this option. More information can be found in appendix A. Control Panel The optional control panel must be enabled through this menu item. A control panel is a miniature physical representation of the conference room. With this control 111

112 panel you can for instance activate and deactivate a microphone, change the volume, change the operating mode, see the status of the interpreter booths, toggle the auxiliary port status, etc. The control panel can be fully customized to the needs of your conference room. In order to use this you need also a license where camera control is enabled. More information can be found in appendix B. Ambient sound Item still present in menu structure but no longer used System 5 Version Version The version shows you the current software version of the CONFIDEA CU software. 112

113 The language menu overview 5 * Language Usage The language menu is used to change the language the CONFIDEA CU menu is in. There are 6 languages to choose from: English French Dutch German Spanish Italian The operator of the central unit can choose his desired language on the CONFIDEA CU to ease up the configuration process. 113

114 The license menu overview 6 License Usage The CONFIDEA CU comes with a standard license which enables the configuration of two interpreter languages and camera control. New licenses can be applied for to enable a higher number of interpreter languages. The license menu can be used to view: the serial number of the CONFIDEA CU, and the current license of the CONFIDEA CU. You can also enter a new license into the CONFIDEA CU so that the number of configurable interpreter languages is upgraded. To enter a new license you should have received a license code in the following form: XXXX-XXXX-XXXX-XXXX This code is entered by selecting the appropriate value of the first character by turning the scroll wheel and pressing ENTER. The same is done for all other values until the new license code is fully entered. 114

115 Troubleshooting If problems occur Replacing a fuse If the fuse of a central unit has blown, the subsequent delegate units cannot be powered. To replace the fuse of a central unit, proceed as follows: Use a screwdriver to carefully loosen the fuse holder and pull it out completely. Remove the fuse. This is the faulty fuse. Now replace the fuse. The specifications for the replacement fuse are shown above the fuse holder. Tips for troubleshooting Delegate unit does not work Check if the system cable between the central unit and the delegate unit is defective or if the system cable has been pulled out. Check if the central unit is connected to the mains and if they are turned on. No microphones except the chairman microphone can be set active Check the TMS submenu on the central unit. Check if the maximum number of microphones that are allowed to be up is not set to zero. If this is the case, alter this value and set it to at least

116 Maintenance and care Use a damp cloth for cleaning the components of the conference system from time to time. Never use solvent-containing cleansers, as these could damage the surfaces of the components. 116

117 Appendix A: Camera Control Protocol Overview The Wired Confidea Digital Conference & Interpretation System supports a camera control. The commands which the camera control should understand will be described shortly. The camera control must be connected to the CONFIDEA CU through a RS232 connection. The appropriate port to use on the CONFIDEA CU is COM2. The communications port COM2 operates at a speed of bits per second. A complete overview of the settings of the communications port for the camera control: Bits per second: Data bits: 8 Parity: None Stop bits: 1 Flow control: None Note however that in order to activate the camera control on the central unit you have to own a license which entitles you to. 117

118 Commands All commands sent by the CONFIDEA CU start with a % sign. The last character is a character which states the end of the transmission. Just before the end of transmission character, there are four characters within the command sent to the camera control which account for the CRC checksum. The CRC checksum is in uppercase hexadecimal form while all other numbers are in decimal form. The protocol is described as follows: With: STX % data CRC ETX STX = start transmit char (0x25 = % ) ETX = end transmit char (0x0D) CRC = 16 bit sum of the ASCII characters between STX and CRC We will adopt a certain notation to explain the messages sent. All separate entities in a message are represented between curly brackets. If the contents of such an entity is also between quotes ( ) then this means that this is a literal string. Otherwise it describes the logical entity. A logical entity will also contain a number between brackets. This number states how many characters the entity will exist of. If the subtext 1+ is attached to the entity between curly brackets, then this means that one or more occurrences of this entity may occur. Maybe this notation seems a little hard to comprehend at first, but some examples should clarify them. Whenever a microphone of a delegate or the microphone of the president is activated, then a command is sent to the camera control. Whenever an active microphone is deactivated, another command is sent to the camera control. The microphone of the president is activated: { % }{ P }{Microphone number (4)} {CRC (4)} The microphone of the president is deactivated: { % }{ p }{Microphone number (4)} {CRC (4)} The microphone of a delegate is activated: { % }{ M }{Microphone number (4)} {CRC (4)} The microphone of a delegate is deactivated: { % }{ m }{Microphone number (4)} {CRC (4)} 118

119 The remaining commands are control commands. First microphone has been activated and the camera control should become active. { % }{ 1 }{ R }{ 00 }{{CRC (4)} All active microphones are deactivated and the camera control should reset itself to a neutral starting position. { % }{ 1 }{ r }{ 00 }{CRC (4)} At a time-interval of around 5 seconds a synchronization message is sent to the camera control. The message contains all the numbers of the active microphones or the number 0 to stipulate that there are no microphones active. { % }{ S }{Microphone Number (4)} 1+ {CRC (4)} All active microphones are deactivated simultaneously. { % }{ V }{ 0000 }{CRC (4)} Examples If the president microphone is activated, and the president microphone has the number 0001 then the following message is sent: %P When the president microphone is deactivated, then the following message is sent: %p If a delegate microphone is activated, and that delegate microphone has the number 0003 then the following message is sent: %M When the delegate microphone is deactivated, then the following message is sent: %m Suppose now that the delegate microphone with number 0003 is active. On a synchronization check the synchronization message will look like this: %S Suppose now that the delegate microphones with number 0002 and 0004 are also active. On a synchronization check the synchronization message will look like this: % C When no microphones are active, then the following synchronization will be received: %S When the camera control system should reset itself to its start position, then the following message will be received: %1r

120 120 When all microphones are deactivated simultaneously, then the following message is received: %V

121 Appendix B: Control Panel Protocol Overview The Wired Confidea Digital Conference & Interpretation System supports a control panel such as AMX, Crestron (ie Dataton, ). The commands which the control panel should understand will be described shortly. The control panel must be connected to the CONFIDEA CU through a RS232 connection. The appropriate port to use on the CONFIDEA CU is COM2. The communications port COM2 operates at a speed of bits per second. A complete overview of the settings of the communications port for the control panel: Bits per second: Data bits: 8 Parity: None Stop bits: 1 Flow control: None REMARK : When TCS 2500 Application Programming Interface is used to manage the Wired Confidea microphone system and voting system, then the appropriate port to use on the CONFIDEA CU is COM3. 121

122 Commands All commands sent by the CONFIDEA CU start with a % sign. The last character is a character which states the end of the transmission. Just before the end of transmission character, there are four characters within the command sent to the control panel which account for the CRC checksum. The CRC checksum is in uppercase hexadecimal form while all other numbers are in decimal form. The protocol is described as follows: With: STX % data CRC ETX STX = start transmit char (0x25 = % ) ETX = end transmit char (0x0D) CRC = 16 bit sum of the ASCII characters between STX and CRC We will adopt a certain notation to explain the messages sent. All separate entities in a message are represented between curly brackets. If the contents of such an entity is also between quotes ( ) then this means that this is a literal string. Otherwise it describes the logical entity. A logical entity will also contain a number between brackets. This number states how many characters the entity will exist of. If the subtext 1+ is attached to the entity between curly brackets, then this means that one or more occurrences of this entity may occur. Maybe this notation seems a little hard to comprehend at first, but some examples should clarify them. Whenever a microphone of a delegate or the microphone of the president is activated, then a command is sent to the control panel. Whenever an active microphone is deactivated, another command is sent to the control panel. This is also valid when a microphone goes into request. The control panel is also able to send commands to the central unit. One command is sent to activate/deactivate a microphone. There is also a command that can be sent to the central unit if you want to reboot the control panel. Also the test generator can be activated or deactivated. Other commands allows you to alter the volume and conference mode. We will divide the discussion of the commands into two categories. The first category describes the commands coming from the central unit and going to the control 122

123 panel and the second category describes the commands coming from the central unit and going to the control panel. The Commands sent by the central unit and received by the control panel: A microphone is activated: { % }{ 1 }{ L }{Microphone number (4)} {CRC (4)} A microphone is deactivated: { % }{ 1 }{ l }{Microphone number (4)} {CRC (4)} A microphone goes into request: { % }{ 1 }{ D }{Microphone number (4)} {CRC (4)} All microphone should be reset: { % }{ E }{ 00 } {CRC (4)} Function key pressed on president unit { % }{ [ }{ F }{Menu ID (2)}{Function key(2)}{action ID (3)}{CRC (4)} When configured, the chairmen units can initiate an action by selecting a user defined menu and pressing a function key. The menu ID indicates the selected user menu on the delegate unit: Name MENU_FUNCTION_KEYS_1 4 MENU_FUNCTION_KEYS_2 5 MENU_FUNCTION_KEYS_3 6 MENU_FUNCTION_KEYS_4 7 The function key corresponds to the pushed button on the chairman unit: ID 123

124 Function key Vote button 1 0 Vote button 2 1 Vote button 3 2 Vote button 4 3 Vote button 5 4 The action that is assigned to the function key is provided in the Action ID ID The commands sent by the control panel and received by the central unit: Activate/deactivate a microphone with number : { % }{ 1 }{ T }{Microphone number (4)}{CRC (4)} Restart the control panel and get information about the microphones to reinitialize the control panel: { % }{ 1 }{ V }{CRC (4)} Set the volume and tone settings for the delegate s loudspeaker. The POTVAL value represents the volume and must be a number between 0 and 12. Also the low, mid and high values must be numbers between 0 and 12. { % }{ 1 }{ X }{POTVAL(2)}{High(2)}{Mid(2)} {Low(2)}{CRC (4)} Change the operating mode. In the table the MODE number is given for each operating mode. MODE Operating Mode MODE Operating Mode 00 No Request 05 Group 1 01 With Request 06 Group 2 02 With Request No Clear 07 Group 3 03 Direct Access 08 Group 4 04 FIFO 09 Override { % }{ 1 }{ U }{MODE(2)} {CRC (4)} Turn ON the test generator: 124

Examples If a microphone is activated, and the microphone has the number 0001 then the following message is sent to the control panel from the central unit: %1L E If the same microphone is deactivated, then the following message is sent to the control panel from the central unit: %1l E 125

126 If the microphone with number 0002 goes into request mode, then the following message is sent to the control panel from the central unit: %1D When all microphones should be turned of, then the following command is sent to the control panel from the central unit: %1E0000D6 When the control panel wants the central unit to activate a microphone, for instance the microphone with number 0002, then the following command is sent: %1T When the control panel wants to restart the control panel and wants to receive the correct information about the active microphones and the microphones on request, then the following command is sent to the central unit: %1V0087 When the control panel wants to change the conference mode then the following command is sent to the central unit: %1U0400EA When the control panel wants to mute the loudspeaker of all units the following command is sent to the central unit: %1X B. The default volume setting can be set by sending the following command to the central unit: %1X

127 Appendix C: Analog Output Device (AOP) manual Overview The AOP2500 unit allows connecting of analog equipment (such as IR modulators, sound reinforcement amplifiers, analog cassette recorders etc ) to the CONFIDEA CU Digital central unit. It is equipped with 9 D/A converters and outputs the floor language channel and up till 8 translated channels. Power is taken from the CONFIDEA CU. Channel 0 is always the floor language. Channel 1 can only be configured freely by rotary switch programming (internal). Channels 2 to 8 are the next consecutive channels of channel 1. Three LED s are on the front: one to indicate power, one to indicate sync and one to indicate that modulation is present at the floor channel. Connectivity Nine 3 pin XLR M connectors (balanced, X former coupled). Two RCA phono connectors for floor language output. Eight RCA phono connectors for translated language outputs.

129 Configuration Channel 0 (CH0) is always the floor language. Channel 1 (CH1) is the reference channel and is only by hardware configurable. The other channels (CH2 to CH8) are the next consecutive channels of channel 1. The configuration of channel 1 depends on the Rotary switch and the DIP switches. The value of channel 1 is the sum of the values of the Rotary switch and the DIP switches. The value of the Rotary switch is marked on the switch. The value of the DIP switches is 0 if both switches are off, in all other cases is the value 16. DIP switches 2 1 Rotary switch CH0 CH1 (ref.)

130 Remote Control There is a voltage free contact that is closed when a microphone is active and that is open when no microphone is active. The CONFIDEA CU controls this voltage free contact. At the backside of the unit, the Phoenix connector is numbered from left to right (non removable connector). Maximum load current(continuous) = 1A Maximum load voltage = 60V Maximum load current (continuous) = 1.8 A Maximum load voltage = 60V On-Resistance = 0.5Ω On-Resistance = 0.15Ω This connector Phoenix is directly connected to the LCA710 driver IC. 130

131 Leds on the front panel When the AOP2500 has modulation present at the floor channel, the floor led (green) will illuminate. (The voltage free contact will close when the floor led illuminates). When the AOP2500 has sync, the sync led (green) will illuminate. When the power of the AOP2500 is good, the power led (green) will illuminate. 131

134 Appendix E: Connecting Confidea Access Point to CONFIDEA CU Overview When Confidea system is used in TCS2500 coupled mode, the Confidea Access Point needs to be connected to one of the PORT1-6 sockets of the CONFIDEA CU central, just as any other delegate unit Via this connection, the communication and audio signals between Confidea Access Point and CONFIDEA CU are handled. This connection also provides DC power supply from the CONFIDEA CU to the Confidea Access point. So no separate 220Vac/24Vdc adapter needed to feed the Confidea Access Point, although it is still allowed to use one. Initialisation of Confidea WDU s is done just as any other type of delegate unit 134
