7 A. Introduction The Telecor Controlled Discussion System (CDS) is a modular conference system that is ideal for portable and permanent conferences. It consists of a Unit Controller that can support and manage up to 120 Floor Units, which are available in Delegate or Chairman models. The level of control is set by the operator, thereby allowing the CDS to easily adapt to various conference proceedings in either formal or informal gatherings. Installation is quick and simple, as each Floor Unit is connected to one another in a daisy-chain arrangement. A user-friendly programming interface on the Unit Controller determines audio settings and how the proceedings will be controlled. A configuration is set by using screen menus displayed on a 2x20 LCD, which are accessed and navigated through with four front-panel push buttons. Once a configuration is set, the Unit Controller assumes responsibility for managing the conference, thereby negating the need for an operator. In addition, the Unit Controller has an RS-232 port which, when used in conjunction with Added Value Firmware, supports a PC connection. This allows for computer-based management using touch-screen software (such as the Telecor Visual Console for CDS application) or a connection with a third-party control system for integration with camera and video systems. This manual details the installation and configuration of the equipment required for the Controlled Discussion System. This manual is intended for the system installer who should have an understanding of sound systems and electronics. CDS Installation and Configuration Manual Page A-1

8 A.1 Standard Features Listed below are the standard features of the CDS: Delegate Limit: Automatic Queuing: Priority: VOX: Talk Limit: Timed Release: Disable Speakers: The Delegate Limit sets the maximum number of Delegate Units that can have access to the floor at one time (the number of live Delegate Unit microphones). This limit can be set from one to 120. Delegate Units that request to speak when the Delegate Limit has been reached are automatically placed in a queue. The order in which a Unit is placed in the queue (the hierarchy) is dependent upon a Unit s priority, with higher level Units being placed ahead of lower level Units. The order for Units with equal priority is set on a first-come first-serve basis. Up to four separate Priority levels can be assigned to a Floor Unit. Priorities set the hierarchy of override provisions for the Floor Units, which vary depending if the Delegate Limit is reached or not. In addition, the mute function for a Chairman Unit is enabled or disabled depending on the priority assigned to the Unit. The system can be operated in either a VOX-Enabled or Disabled mode. In VOX-Enabled the microphone remains off until the user speaks. In the VOX- Disabled mode, the microphone remains live for the duration of time that the participant has the floor. Talk Limit determines the length of time a Unit has access to a floor. The time can be set in one-minute increments from 1 to 60 minutes. Timed Release determines the length of time that a Floor Unit remains active after the user stops speaking. Once this time is exceeded, the floor is passed onto the next participant in the queue. This time can be set in five-second increments from 15 to 60 seconds. The speaker on a Unit can be disabled so that it functions only as a microphone station. Disable Microphones: The microphone on a Unit can be disabled so that it functions only as a speaker station. Input Signals: Floor Signal Equalization: The Unit Controller includes inputs for a microphone, a balanced line level signal, and an unbalanced line level signal. Each external input signal can be independently adjusted. The Unit controller has a built-in Hi/Lo shelving type equalizer. The equalizer provides up to 10dB of boost or cut at frequencies below 100 Hz, as well as 10dB of boost or cut at frequencies above 10 khz. Page A-2 Introduction

9 Automatic Feedback Suppression: External Processor: Monitoring: Output signals: Save Configuration: The Unit Controller includes the intelligence to automatically decrease the floor signal level if feedback occurs. Provisions have been made for the insertion of additional external signal processing equipment (graphic equalizer, compressor, frequency shifter, etc.) into the floor signal path. Up to five different signals (Floor, Floor and External Inputs, Processed Floor, Processed and Equalized Floor and External Input, and Main Output) can be monitored aurally using a headphone jack, and visually using a volume unit bar graph on the LCD. The Unit Controller includes ports for the output of a balanced and unbalanced line level signal. A total of four signals (floor, floor and external inputs, microphone, or main output) are available for output. The Unit Controller allows up to six custom Configurations to be saved for retrieval later. This is ideal for applications where the CDS hosts different and unique conference proceedings. A.2 Optional Features RS-232 Connection: Visual Console for CDS: The RS-232 port is supported by Telecor Added Value Firmware 1 to allow for a connection to a PC or a camera and video system. A PC connection enables touch-screen software, such as Telecor Visual Console for CDS, to control conference activities. A camera and video system, connected either directly or indirectly through a third-party control system, can visually display conference participants based on the CDS protocol transmitted from the RS-232 port. Visual Console for CDS is a software package designed specifically for PC control of the CDS. It provides a visual representation of the configuration set-up, allowing the user to easily control the CDS from a PC. 1 Telecor Added Value Firmware consists of the following part numbers: CDS-VC-30, CDS-VC-60, CDS- VC-90, and CDS-VC-120. See Section C.9.3 RS-232 Port, for more information CDS Installation and Configuration Manual Page A-3

10 A.3 Applications To demonstrate the versatility and flexibility of the CDS, five examples showing various types of assemblies are provided. A.3.1 Basic Discussion System Delegates participate (talk and listen) in the conference using individual Floor Units. Proceedings are controlled with a user-determined configuration set up on the Unit Controller. The diagram below shows a straightforward conference of 15 Delegate Units and a single Unit Controller. Page A-4 Introduction

11 A.3.2 Discussion System with Audience Participation The conference is open to audience participation, such as what would be required at a city or town council meeting seeking public input. Floor Units consist of both Delegate and Chairman Units. Each Delegate would be typically set to the same status, while VIP and Chairman Units would be set to a higher priority status. The Chairman Unit would be able to override all other delegates. An audio output from the Unit Controller is connected to an external power amplifier, providing a public address facility for the audience. An input for a floor microphone allows the audience to participate in conference proceedings. CDS Installation and Configuration Manual Page A-5

12 A.3.3 Discussion System at Full Capacity The CDS is at its full capacity (120 Floor Units), controlled by a CDS-DC-60 Unit Controller and a CDS-E-60 Expansion Unit Controller. The Unit Controller is equipped with a variety of line level inputs and outputs that enable external analogue equipment used for broadcasting or recording to be connected to the Controller. In addition, audio processing equipment such as an equalizer or compressor may be connected into the signal path of the Unit Controller to enhance the system audio. Page A-6 Introduction

13 A.3.4 Discussion System with Management Software The Telecor Visual Console for CDS application is being used to control the CDS from a PC connected via the RS-232 port. 1 Visual Console for CDS provides a graphical representation of the conference floor using Delegate and Chairman icons. The icons are functional and are used as status indicators or as touch points to manually control Floor Units. 1 The RS-232 port is supported by Telecor Added Value Firmware. See Section C.9.3, RS-232 Port for more information CDS Installation and Configuration Manual Page A-7

14 A.3.5 Discussion System Integrated with Camera System The CDS is connected to a third-party control system (i.e., PLC) via the RS-232 port, 1 allowing for integration with camera and video systems in order to display images of participants on television monitors, projectors screens, or other video mediums. The RS-232 port transmits operating and configuration information about the CDS, such as when a Floor Unit becomes active. The Control System, using a pre-configured script or driver, then converts the message to the protocol of the Camera System. The Camera System, having been preprogrammed with location presets of each Floor Unit, receives the message from the Control System and then pans to the location of the active Floor Unit. Note If the protocol of the Camera System can be configured to accept the Telecor CDS protocol, then the involvement of the third-party Control System is not required. This allows the Telecor CDS to control the Camera System directly. 1 The RS-232 port is supported by Telecor Added Value Firmware. See Section C.9.3, RS-232 Port, for more information. Page A-8 Introduction

15 B. Equipment Overview The Telecor Controlled Discussion System (CDS) consists of the following: Floor Units - Available in Portable or Flush-Mounted versions Unit Controller - Available in Versions supporting 30 or 60 Floor Units Expansion Unit Controller (optional) - Expands Floor Unit Capacity of System.

23 C. Installation This section covers the installation of the Unit Controller, any Expansion Unit Controllers, the Floor Units, and any external devices. C.1 Quick Start Procedure In order to allow a first-time user to quickly and efficiently begin using the CDS, Telecor has outlined a Quick Start Procedure that guides you through the installation procedure and some basic configuration programming. The Quick Start Procedure allows a basic system, as described in Section A.3.1, Basic Discussion System, to be set up, which consists of a quantity of Delegate Units and a Chairman Unit. The operating configuration that Quick Start sets up is referred to as a controlled configuration, where the delegates request to speak by activating a button on the Floor Unit. The Unit Controller maintains delegates in queue based on the chronological order that the requests are made, or First-In First-Out (FIFO). The Chairman Unit has priority, which allows the Chairman to either join a discussion at any time or interrupt a discussion while muting all other delegates. The Quick Start Procedure consists of 10 sections in the Installation and Configuration chapters that are identified by the following label. The outline of the entire procedure is shown in the flow chart on the next page. The Quick Start Procedure is only intended to get you started and will enable you to configure the system based on the Factory Default Configuration (See Appendix 3: Default Configuration.) This is the most basic of configurations. In order to explore the full potential of the system, Telecor encourages you to become familiar with the detailed information contained in this manual. The CDS is extremely versatile, with capabilities to address even the most complex of conference and discussion applications. CDS Installation and Configuration Manual Page C-1

26 INSPECT FOR SHIPPING DAMAGE: Visually examine all items for apparent damage. If any is observed, contact the shipping company immediately. VERIFY ITEMS WITH PACKING SLIP: Verify that all of the equipment listed on the packing slip is present. Notify Telecor of any shortages immediately. Page C-4 Installation

27 C.3 Setting Floor Unit Addresses Each Floor Unit has a DIP switch that allows the Unit to be set with a unique address. A unique address is required so that the Floor Unit is recognized by the Unit Controller for configuration and proper operation. Set these addresses before connecting the Floor Units. The DIP switch consists of 8 switches that represent the Unit address in binary format. Switches 1 through 7 are used to determine the address, and 8 is used for mute button mode of operation (See Section C.4 ). A lowered switch is off and a raised switch is on. The value of a raised switch depends on the switch position: Switch Position Value For Mute Button Mode of Operation The Unit address is the sum value of all raised switches. For example, if switches 4 (value 8) and 7 (value 64) were raised, the address would be 72 (8 + 64). On the bottom of each Floor Unit, in the Unit Address box, write down the address using indelible ink.

34 C.6.2 Connecting Cable between Controller and Conference Area Materials Required: Cable consisting of 3 individual shielded twisted pairs, 20 AWG with overall PVC jacket (Belden 9873 or equivalent) (not provided) One 8-pin female DIN receptacle (not provided) One 8-pin male DIN connector (not provided) Backbox for DIN receptacle (not provided) Each Floor Unit Port on the back of the Unit Controller or Expansion Unit Controller (see page C- 10) supports 30 Floor Units. A cable from a Floor Unit Port (labelled TO CDS-CU/DU UNIT) is typically run via conduit to the permanent conference area and terminates at a wall or floor-mounted DIN receptacle, which in turn terminates a maximum run of 30 Floor Units. Multiple cables may be run in the same conduit. Cable requirements between a Controller Floor Unit Port and the floor or wall-mounted DIN receptacle consist of 3 individual shielded twisted pairs, 20 AWG, with an overall PVC jacket (Belden 9873 or equivalent). Cable Length When installing a run of Floor Units, the overall cable length from the Controller to the last Floor Unit on the run must be taken in to consideration due to line loss. The more Floor Units on the line translates into a shorter cable length, while less Floor Units translates into longer cable length. The chart below will help you determine the maximum cable length for a run of Floor Units. Floor Units Maximum Cable Length (Belden 9873 or Equivalent) ft ft ft Page C-12 Installation

35 Wiring DIN Connectors The cable end at the Controller terminates with an 8-pin male DIN connector that connects to the port labelled TO CDS-CU/DU UNITS. Solder the wires from the cable onto the appropriate points of the DIN connector following the diagram below. Please note that the shield from the audio pair and the shield from the data pair share the same termination point. The cable end at the permanent conference area terminates with an 8-pin female DIN receptacle that typically mounts on a floor or wall box. Solder the wires from the cable onto the appropriate points of the DIN receptacle following the diagram below. Please note that the shield from the audio pair and the shield from the data pair share the same termination point.

These custom buttons (not supplied by Telecor) are installed in a separate panel and will operate in parallel with the Microphone Panel buttons. Ports for these buttons can be found at J14 on the Microphone Panel. C.6.4 Interconnecting Flush-Mounted Floor Units The DIN receptacle in the floor or wall box terminates the Remote Module of the first Floor Unit. Additional Remote Modules are interconnected using standard cabling terminated at the DIN receptacles of each Remote Module and/or using Belden 9873 or equivalent cable terminated onto the 8-pin socket block connector of each Remote Module. Note: The maximum overall cable length (of each run or chain) between the Unit Controller and last Floor Unit cannot exceed 400 feet. Using DIN Receptacles for Interconnection 1. Using standard six-foot CHAP-DU-6 cables, connect the Remote Modules of each Floor Unit via the DIN receptacles. The two DIN receptacles on a Floor Unit are interchangeable. If extra length is required between the Floor Units, use the optional 12-foot CHAP-DU-12 cables (ordered separately). Remember that the maximum number of Floor Units on a run is 30. CDS Installation and Configuration Manual Page C-17

40 2. The last Floor Unit of each run must have its END UNIT header pins shunted to identify the unit as the end unit. See Section C.7, End Floor Unit Terminator for more information. Using 8-pin Socket Block Connectors for Interconnection The 8-pin socket block connectors can be used in lieu of or in combination with the DIN receptacle connection method. Complete the following steps: 1. Unplug the 8-pin socket block from the header pins of the Remote Module. Terminate the Belden 9873 wires into the socket block following the diagram below. The diagram below shows a single cable connection to a socket block. In most cases, the socket block terminates two cables, one coming from the previous Remote Module and one going to the next Remote Module in the daisy-chain in a parallel fashion. If the socket block is to secure two cables, terminate the wires from the cable going to the next Remote Module in the chain before securing the first set of wires into place. Note: Please note that the shield from the audio pair and the shield from the data pair share the same termination point. 2. Once the wires are terminated into their proper positions, secure them into place with a precision flathead screwdriver and plug the socket block back into the header pins. 3. Wire additional Remote Modules in the same manner. The last Remote Module in the chain only terminates one set of wires. Remember that the maximum number of Floor Units on a run is 30. Page C-18 Installation

41 4. The last Floor Unit of each run must have its END UNIT header pins shunted to identify the unit as the end unit. See Section C.7, End Floor Unit Terminator for more information. CDS Installation and Configuration Manual Page C-19

42 C.7 End Floor Unit Terminator The last Unit on a run (or chain) or Floor Units must be configured so that it is identified as the end unit. This is accomplished by vertically installing two shunts onto its END UNIT header pins. These pins are located to the right of the DIP Switch on the rear of the Unit. Note: When using a CDS-DC-60 there are up to two runs (or chains) of up to 30 Floor Units per run (60 total); the last Floor Unit of each run must be terminated. With a CDS-DC-60 and a CDS-E-60 there may be up to four runs (or chains) of up to 30 Floor Units per run (120 total). The last Floor Unit on each of the runs (up to four) must be terminated. Materials Required: Two shunts for a CDS-DC-30 (provided) Two shunts for a CDS-E-30 (provided) Four shunts for a CDS-DC-60 (provided) Four shunts for a CDS-E-60 (provided) Page C-20 Installation

43 C.8 Connecting the Expansion Unit Controller Connect the six-inch 8-conductor ribbon cable connector from the TO EXPANSION UNIT port on the Unit Controller to the equivalent port on the Expansion Unit Controller. Plug the Unit into a regular AC wall outlet or power bar. Materials Required: One Six-inch 8-conductor Ribbon Cable (provided with Expansion Unit Controller) One 110VAC or 220VAC power cord (provided with Expansion Unit Controller) Note: If the CDS includes an Expansion Unit controller, power up the Expansion Unit Controller before powering up the Unit Controller. This allows the Unit Controller to recognize the Floor Units connected to that Expansion Unit Controller CDS Installation and Configuration Manual Page C-21

44 C.9 External Connections The Unit Controller includes an input for a microphone, and inputs for a balanced and an unbalanced line level signal from an external audio source. A balanced and an un-balanced line level output are available for the external broadcast or recording of various signals (see Section D.8, Outputs. ) In addition, each Floor Unit Port has an accompanying unbalanced output for the external broadcast or recording of its zone (the Floor Units connected to the Floor Unit port). An external Processing Unit can be connected for the alteration of the floor signal (see Processing Unit, Section C.9.1 ). Refer to the diagram below for the location of the various input and output ports. C.9.1 Processing Unit The Unit Controller includes an unbalanced output and input port for the connection of an external Processing Unit for alteration of the floor signal. The signal level at the output is -10dBu (300 mv rms) nominal. The gain of the Processing Unit should be set to unity since the input is expecting a -10dBu level as well. After the Processing Unit is connected, remove the shunt located at BYPASS, which is situated between the Processing Unit ports. Page C-22 Installation

45 C.9.2 Line Level Inputs/Outputs and Microphone Connections The level of the various output signals provided by the Unit Controller is 0.3 V rms. The level of any input line level signals should also be 0.3 V rms. The microphone signal should be of low impedance. Equipment is connected to the unbalanced input/output terminations via standard phono connectors located on the back of the Unit Controller. Equipment connected to the balanced input/output terminations, as well as the microphone, are connected via XLR-3 type connectors using two wires and a shield as shown in the figure below. C.9.3 RS-232 Port A Model A Unit Controller running Telecor Added Value Firmware supports the RS-232 port, which allows for a connection to a PC or a camera and video system.

The Unit Controller offers four separate signals for external broadcast via its balanced and un-balanced output ports, which are described below: Floor: Floor and External Inputs: Main Output: Microphone: Consists of Floor Signal without any alteration through Processing Unit or Equalizer. Consists of the unaltered Floor Signal, external Input Signals, and the Microphone Signal. Consists of Floor Signal altered through Processing Unit and Equalizer, along with external Input Signals, and the Microphone Signal. Consists of just the Microphone Signal. To select a signal for external broadcast, complete the following steps: 1. Enter SETUP > Outputs. 2. Depending on the connection, select either Balanced O/P Source or Un-Balanced O/P Source. 3. Select a signal from above and press ENTER. The signal blinks twice to verify that it has been set. CDS Installation and Configuration Manual Page D-21

68 D.9 Operation Sub-Menu Once the outputs have been selected for external broadcast, use the Operation Sub-Menu to set the level of the Main Output and various external Inputs, enable the Feedback Suppressor, set the Equalizer, and select the audio signal for monitoring on the headphone jack. The diagram below outlines the structure of the Operation Sub-Menu. Page D-22 Configuration

69 D.9.1 Levels The levels of the following audio signals can be adjusted with the Unit Controller: Main Output: Microphone Input: Balanced Input: Unbalanced Input: The audio signal that is being transmitted to the Floor Unit speakers. It consists of a mix of the floor signal (altered through a Processing Unit or the internal equalizer), the microphone signal, and the signal from the balanced and unbalanced inputs. The floor signal refers to the raw audio from the Floor Unit microphones. The signal from the microphone connected to the MICROPHONE port. The signal from the external audio source connected to the BALANCE IN port. The signal from the external audio source connected to the UNBAL. IN port. To adjust the level of an audio signal, complete the following steps: 1. Enter OPERATION > Levels. 2. Select one of the above four signals that you wish to set the level of, and press ENTER. 3. By pressing the UP and DOWN buttons, the percentage number on the right side of the screen changes accordingly. This number represents the percentage of total available output. If a signal is present while the adjustment is being made, the volume unit (VU) bar graph illuminates until the nominal level is reached. This is indicated by the large vertical bars on the far right of the display. When adjusting audio levels, ensure that the peak signal does not exceed the nominal level bars. CDS Installation and Configuration Manual Page D-23

70 Note 1: A typical Main Output level is 75%. It is recommended that the Main Output level be set first by adjusting the level until the audio being broadcast through the Floor Units is at a satisfactory level, yet below the feedback threshold. Note 2: Once the Main Output level is set, then the Microphone, Balanced and Un-Balanced signal levels can be set as necessary. If these inputs are not used, then set the levels to 0. Page D-24 Configuration

71 D.9.2 Monitor The Unit Controller has a built-in headphone jack, along with a front panel volume control, that allows the user to aurally monitor a variety of signal paths. These signal paths are individually selected and described in the table below. You may also refer to the Signal Flow Block Diagram in Section B.5. Affected by Processing Unit (for Floor Signal only) Affected by Internal Equalizer (for Floor Signal only) Affected by Main Output Level Floor Floor Signal Floor and External Inputs Floor Signal, Microphone Signal, External Input Signals Processed Floor Floor Signal Processed and Equalized Floor and External Inputs Floor Signal, Microphone Signal, External Input Signals Main Output Floor Signal, Microphone Signal, External Input Signals No No No No No No Yes No No Yes Yes No Yes Yes Yes CDS Installation and Configuration Manual Page D-25

72 To monitor a signal, complete the following steps: 1. Enter OPERATION > Monitor. 2. Choose from one of the five signals in the table above and press ENTER. 3. When the signal is active, it can be heard through headphones plugged into the Unit Controller s headphone jack and is represented as a VU bar graph on the LCD. The example below displays the VU bar graph of the Floor Signal. Page D-26 Configuration

73 D.9.3 Feedback Suppression The Unit Controller has a built-in Feedback Suppressor. The controller can automatically sense runaway feedback, upon which it automatically drops the gain by 5dB, immediately stopping the feedback. Then gradually the gain is restored at a rate of 1dB/0.2 sec to 1dB less than the previous value. This process will quickly suppress feedback once it starts, and then slowly bring the levels back up to just a little less then where feedback previously occurred. The whole process will repeat should feed back re-occur, once again dropping the gain a further 1 db lower than the previous level. The process continues until no more acoustic feedback occurs yet there is enough gain for the system to operate effectively. Note: Automatic Feedback Suppression should not be relied upon to set the Main Output level. The Main Output Level should be set prior to enabling Automatic Feedback Suppression. Automatic Feedback Suppression is designed to provide a temporary solution in the case that feedback occurs. If feedback does occur the Automatic Feedback Suppression will activate, but the technician probably still needs to readjust the Main Output Level. CDS Installation and Configuration Manual Page D-27

74 Feedback Suppression may be enabled or disabled. It is recommended that the Main Output Level be set prior to enabling this feature. (see Section D.9.1, Levels. ) To enable (or disable) Feedback Suppression, complete the following steps: 1. Enter OPERATION > Feedback Suppression. 2. In the FEEDBACK SUPPRESSION screen, two items are available: On - Enables feedback suppression Off - Disables feedback suppression 3. Select the required item and then press ENTER. The item blinks twice to verify that it has been set. Page D-28 Configuration

75 D.9.4 Equalization A High/Low shelving type equalizer is included in the Unit Controller. The equalizer provides up to 10 db of boost or cut at 300 Hz, as well as 10dB of boost or cut at 5 khz. Use the equalizer to achieve the truest reproduction of sound quality, increase the intelligibility, or decrease feedback. Adjusting the Low Frequency To adjust the low frequency portion of the audio spectrum, complete the following steps: 1. Enter OPERATION > Equalizer. 2. Two screens are available: Low Freq. Equalizer - below 100 Hz High Freq. Equalizer - above 10 khz 3. Select the LOW FREQ. EQUALIZER screen and press ENTER. A bar graph is displayed. 4. Use the UP and DOWN buttons to adjust the boost and cut of the low frequency. 5. The effect of the adjustments can be heard through headphones plugged into the Unit Controller s headphone jack. When low frequencies are boosted, the sound is richer or fuller. Conversely, when low frequencies are cut, the sound is thinner or tinny. CDS Installation and Configuration Manual Page D-29

76 Adjusting the High Frequency To adjust the high frequency portion of the audio spectrum, complete the following steps: 1. Enter OPERATION > Equalizer. 2. Two screens are available: Low Freq. Equalizer - below 100 Hz High Freq. Equalizer - above 10 khz 3. Select the HIGH FREQ. EQUALIZER screen and press ENTER. A bar graph is displayed. 4. Use the UP and DOWN buttons to adjust the boost and cut of the high frequency. 5. The effect of the adjustments can be heard through headphones plugged into the Unit Controller s headphone jack.
