13 1.2 System equipment 1. Conference Main Unit (CMU) The Conference Main Unit forms the core of the entire conference system. It provides power supply to all contribution units and serves as key component to link system hardware to application software. In stand-alone mode without a PC, the CMU only carries out basic management facilities; while more comprehensive management facilities can be implemented in PC-controlled mode. In a PC controlled system, the CMU and the PC use the advanced TCP/IP protocol. Theoretically, the communication distance between the PC and the CMU can be infinite. This is decisively different to traditional RS-232 connection modes where the distance between the PC and the CMU cannot exceed 15 metres. TCP/IP enables remote control, remote diagnosis and remote update. By using network techniques, conference systems are linked tightly to the rapidly developing internet technology, communication technology and computer science. Users enjoy the convenience of the contemporary leading techniques, e.g. by using the compatible wireless LAN techniques (802.11) - such as PDAs - which can be used to control a conference system wirelessly. The import of network topology also makes the conference system merge with intelligent building networks. The dedicated 6-pin cable (substituted by shielded Cat.5 cable) is used to transmit high quality digital audio, control and other information data, avoiding cables cluttering up the conference venues and adaptable to any system cabling requirements. The professional 6P-DIN standard plug and clasp improve system connection reliability, while facilitate system installation and disassembly; the daisy chain design of contribution units enables the units to be added into the system at any desired point, and simplifies equipment extension and maintenance significantly. 2. Contribution units Contribution units are units used by participants to contribute to a conference. There are different models in HCS-3600 Series for diverse requirements ranging from discussion units, voting units, to upgraded units with discussion, voting, IC-card reader and built-in loudspeaker. There are tabletop and flush-mounting designs available at users option. 3. Accessories Relevant accessories connected or used in HCS-3600 series include: Connections cables, Grounding cable sockets, Earphones/Headphones and Video display card, etc. 4

14 1.3 Application software HCS-3600 application software is comprehensive, reliable and user-friendly. It is also an easy-care software system which helps the operator to manage the conference efficiently from the very beginning of a meeting until the post-meeting work. Once the PC installed and the HCS-3600 application software integrated into the economic conference system, the operator manages centrally all aspects of the conference. The operation turns out to be easy and efficient. HCS-3600 application software is a modular software with various functional modules: System Setup Management Module, Microphone Management Module, Voting Management Module, Synchronous Audio Recording Management Module, Synchronous Video Recording Management Module, Multi-user Congress Control Management Module, Dual PC Server Hot Spare Module, Agenda Control Module, Speech Prompt Module, etc. 5

15 1.4 Functions and features 1. Set up numbers of active microphones and operation modes Active microphone(s) limit (1/2/4) and speech time limit Four operation modes can be set via the main unit: OPEN mode, after the number of active microphone(s) come to the limit, microphone key with request-to-speak registration (AUTO); OVERRIDE mode, if the limit is achieved, microphone key control with override of the active microphones (FIFO); VOICE mode,automatic voice-controlled mode, sensitivity level can be set; APPLY mode, delegate applies to speak by pressing apply key, delegate can speak only when chairman approved his application; In OPEN/OVERRIDE/APPLY mode,chairman unit can be set as DAIS mode, it will keep active all the time. If chairman unit with graphic LCD is configured in the system, parliamentary voting (YES/NO/ABSTAIN) can be implemented even without PC. The voting result can be displayed on the LCDs of all conference units (voting start and end controlled by chairman unit). 4. Conference sign-in HCS-3600 system takes the leading role in using the complex IC-card sign-in techniques for conference sign-in, i.e. delegate can use the same IC-card for both touched and contactless sign-in. This TAIDEN patent technology has not only simplified authentication and sign-in of the delegates, but has also eased operator s delegate management. Seat sign-in Key-press sign-in Touch IC-card sign-in 2. Multi-chairman unit in one system and delegate units set as VIP With HCS-3600 application software, in one system at most 100 chairman units can be connected, but only 1 chairman unit has control facility. Delegate units can also be set as VIP, as many as 32 VIPs are available in one system. VIP unit can be activated as long as the total of active microphones is not beyond 6 (including chairman/delegate/vip unit). 3. Efficient voting function Comprehensive proposal making; In combination with the corresponding software modules, multiform votings can be implemented: Parliamentary: YES/NO/ABSTAIN Questionnaire: 1/2/3/4/5 Audience response: - -/-/0/+/+ + Appraisal: Satisfied (four/three/two keys voting) Qualified (four/three/two keys voting) Competent (four/three/two keys voting) 5. Information display Conference title, content and related information can be shown on the large screen (or projector); Multilingual (Simplified Chinese, Traditional Chinese and English) menu and information can be shown on contribution unit equipped with graphic LCD. 6. Automatic video tracking Automatic video tracking can be carried out if video switch unit and camera are installed, and the whole conference proceedings and speaking delegate can be recorded (multi-channel recording synchronously are available). 7.

When the delegate voted, the indicating light of his voted key will be activated and all other indicating lights will be deactivated. About 2 seconds later, all indicating lights will blink again, and the delegate can change his/her vote. His/her last voted key will be valid. 5. VIP unit (only for HCS-3641NC/ND) Any delegate unit can be assigned as a VIP unit by the HCS-3600 application software. At most 32 VIP units can be assigned; As long as the active microphone number does not exceed 6 (including chairman/delegate/vip), the microphone of the VIP unit can be activated freely; If the priority mode is configured as All off, all active delegate microphones will be turned off when the chairman presses his priority key, and all active VIP microphones will be muted temporarily. They will restore when the chairman releases his priority key; If the active microphone number reached 6, when the microphone On/Off key is pressed, the microphone cannot be turned on unless one of the active microphones is deactivated. 69

78 Chairman unit The chairman unit features all the functions of a delegate unit, and the following additional functions: 1. Priority (only for HCS-3641NC) If the priority mode on the main unit is configured as All mute, all active delegate and VIP microphones will be muted temporarily when this key is pressed and they will restore when this key is released; If configured as All off, all active delegate microphones will be turned off and the request-to-speak list will be purged when this key is pressed. All active VIP microphones will be muted temporarily when this key is pressed. They will restore when this key is released. 2. Speaking (only for HCS-3641NC) If the number of active microphones in the system is less than 6 (including chairman /delegate /VIP), the chairman can activate his/her microphone normally, the operation is the same as for the delegate unit (refer to section ). If the number of active microphones in the system is 6, the chairman cannot activate his/her microphone. But he/she can use the Priority key to All mute or All off other microphones and give his/her speech. Without connecting to PC, under OPEN / OVERRIDE / APPLY mode, the chairman unit can be set as DAIS status, in which the microphone of the chairman unit with control function remains active during the meeting. B. Turn off or mute delegate microphone The chairman can use the Priority key to execute All mute or All off operation. 4. Voting (HCS-3641NC does not have this function) This series chairman units do not have LCD display. For voting connection to a PC is mandatory. Connected to PC: When controlled by the application software, nominative or ballot voting are available; First key-press valid or Last key-press valid are available; Voting can be controlled by application software. Voting operation of the chairman unit and the delegate unit are identical. In this mode, voting can also be controlled by the chairman unit. The Start voting indicating light on the chairman unit will blink. Voting starts once the chairman pressed the Start voting key. 3. Controlling delegate unit (only for HCS-3641NC) A. Approve delegate unit s request to speak Under Apply mode, when a delegate requests to speak, a ring tone will be emitted by the built-in loudspeaker in the chairman s unit (ring mode has been configured as ON ). The chairman can now approve delegate s request and activate delegate s microphone by pressing the microphone On/Off key or reject delegate s request by pressing the Priority key. Only one delegate can request to speak at one time. 70

79 Chapter 4 System connection 4.1 Summary HCS-3600 Economic Conference System has a simple but efficient structure. The system installation is simple and quick and does not need special training. Daisy-chain connection is adopted between conference units as well as to CMU via dedicated extension cable. TCP/IP protocol is adopted for Ethernet connection between the CMU and the PC. As a result remote control, remote diagnosis and remote update can be achieved. Application software for client and server runs on one or several computers in the same LAN. The operator is able to control the progress of the meeting flexibly. In this chapter, the connections of HCS-3600 Economic Conference System are introduced by diagrams and examples Connection principles The Conference Main Unit forms the core of the entire conference system. It provides power supply to all contribution units and serves as key component to link system hardware to application software. Since contribution units are powered by the CMU, the total number of contribution units accommodated in a CMU is constrained to the power capacity and control capacity of the CMU. One CMU comes with 3 outlet trunk-line cable connectors, and each outlet accommodates 40 discussion/voting units without LCD or 30 discussion/ voting units with LCD at most, up to 120 discussion/ voting units can be connected to a single CMU. In case more contribution units are needed in a system: EMU(s) are added. A single EMU powers up to 120 discussion/voting units. A single CMU + EMU(s) system controls up to 256 discussion/voting units; Or CMU(s) are added into the local network via HUB. A multi-cmu + EMU(s) system controls up to 256 discussion units or 4096 voting units per multi-cmu system. By using application software, in one system, up to 100 chairman units can be connected, but only 1 chairman unit has control facilities. Any delegate unit can be set as VIP unit, the total number of VIPs being limited to 32. As long as the number of active microphones in the system is less than 6 (including chairman, delegate and VIP), a VIP microphone can be activated freely. Cooperating with IR Language Distribution System, a larger audience can participate in the conference. The CMU can work alone to achieve basic control functions; when cooperated with application software, more powerful and versatile management and control functions are accessible. Conference Main Unit (CMU) models and corresponding function list (refer to table 4.1 for details): Connection Cables Discussion units and voting units use 6-pin cables. HCS-3630 series contribution unit features a 6-pin 2.1-metre cable (plug) and a 6-pin socket on the rear panel. When the units are connected one by one, connect the cable (plug) of the first unit to the outlet (socket) of the CMU. The socket on the rear panel is now connected with the cable (plug) of the next unit - thus contribution units are daisy-chain connected. CBL6PS extension cables can be used between contribution units and the CMU. All other contribution units with a 6-pin connector feature a 1.5-metre cable (plug) and a 0.6-metre cable (socket). When connecting, put the plug of the first contribution unit to the outlet (socket) of the CMU, then connect the plug from the next contribution unit to the socket of the first one. By that all conference units are daisy-chain connected. CBL6PS extension cables can be used between contribution units and the CMU. 71

Due to the voltage drop in the extension cable caused by the ohmic resistance,, the number of contribution units available for each outlet connector will be reduced according to the length of the cable connected to trunk-line. The relationship is described as table 4.2: The extension cable connected between the CMU and the first contribution unit carries the current of all subsequent units and influences at the same time the maximum possible load of the CMU.; However, the influence of a cable connected between the last two contribution units, is insignificant because it carries only the current for the last unit. For instance, a 100-metre extension cable can be connected between the 39th and 40th contribution unit presumed there is no other extension cable used in the corresponding trunk-line.

84 4.5 Connection between CMU and conference Sign-in System The Conference Sign-in System (untouched) aims at providing a reliable, effective and convenient conference sign-in solution for various large conferences. The Conference Sign-in System makes the organizers get updated statistical data of the participants, including the expected number of participants, confirmed sign-in registrations, seat allocation, etc.; these data can be provided synchronously to all participants. Furthermore, the conference moderator is updated automatically as he benefits from a real-time report system, conference topics, agenda, procedure and related information can be displayed on the large screen. The Conference Sign-in System uses both remote RF card and close RF card sign-in technologies (user can choose as needed). Portrait shots and customized surface design can be printed onto the RF card combining delegate's accreditation and ID in a single card. The delegates carry out sign-in simply by walking through the access control containing the RF card reader: a significant simplification of the sign-in procedure and also a shortening of the sign-in time. Client/server mode with anti-virus and security mechanism is also imported in the Conference Sign-in System, moreover, the system is easy to update, to extend and to choose the application software.

87 4.6.2 Connection of the Audio Cable Used in HCS-3600 Series Economic Conference System Cable connection plays an important role in long distance audio transmission. Improper connection will result in noise interference. Three common connections are introduced, taking as example the connection of the TAIDEN system with peripheral devices: 1. Connection for unbalanced:balanced transmission cable : Practical example: after mixing audio signals from external wired and wireless microphones in a mixer, the signal from the unbalanced mixer output goes to the HCS-3600 CMU balanced input LINE IN (Ø 6.4 mm jack). Note: This connection is not applicable to balanced:unbalanced transmission, otherwise, the signal source of the balanced output may be damaged. 2. Connection for balanced:balanced transmission cable: Practical example: after mixing audio signals from external wired and wireless microphones in a mixer, the signal from the balanced mixer output goes to the HCS-3600 CMU balanced input LINE IN (Ø 6.4 mm jack). 3. Connection for unbalanced:balanced transmission cable: Practical example: The recording output of HCS-3600 CMU REC.OUT (unbalanced output) to PA system or Media recording input XLR interface (balanced input). Note: This connection is not applicable to balanced:unbalanced transmission, otherwise, the signal source of balanced output may be damaged. 79

88 4.6.3 Wiring for RJ-45 Plug Used in HCS-3600 Series Economic Conference System 1. Wiring standard While making Ethernet cables using twisted pair cables, we should adhere to ANSI/TIA/EIA-568A (T568A for short) and ANSI/TIA/EIA-568B (T568B for short). The 8 pins assignment in RJ-45 plug: The side with leaf spring faces down, while the side with metal reed faces up, the connection sequence from left to right is shown as follows: 2. Wiring order of Twisted Pair Cable on diverse occasions: The Ethernet cable should have RJ45 plugs on both ends. There are two ways of wiring, one of which is straigh-through cable, the other is cross-over cable. The straight-through cable actually refers to both ends of the cable are wired with the T568A standard or with T568B standard, while the cross-over cable is wired one end with the T568A standard and the other with the T568B standard. In most cases, straight-through cable adapts the T568B wiring standard. In projects using Cat.3 UTP, Cat.5 UTP or S-UTP Cat.5, the T568B standard is adhered to. In case Cat.5 UTP is used, the transmission rate can be as fast as 100 Mbps. Applications and wirings: Computer--Computer: Cross-over cable Computer--Switcher :Straight-through cable Exchanger--Switcher:Cross-over cable or straight-through cable Note: If TAIDEN HCS-3600 System CMU is connected to PC via Ethernet cable, cross-over cable should be used. If the connection is via Switcher or HUB, the communication can be achieved via either cross-over or straight-through cables shown as follows: 3. Function of each pin (1-8) in RJ-45 plug (10BaseT/100BaseTX): 1. TX Data + 2. TX Data - 3. RX Data + 4. Unused 5. Unused 6. RX Data - 7. Unused 8. Unused 80

89 4. Potential risks brought about by unstandardized wiring 1. In case the wiring is unstandardized, connection itself may well exist, but crosstalk between pairs cannot be eliminated effectively. Therefore, the error rate is high and the consistency of the system is affected. 2. Short distance transmission is available while long distance is unachievable. 3. Due to crosstalk, transmission distance cannot reach 100 metres; furthermore, unstandardized wiring may result in big trouble in the future maintenance. 81

93 Chapter 6 Working environment and maintenance Suitable working environment and proper maintenance methods can extend service life of the equipment effectively. For maintenance please read the contents of this section carefully. 1. Public areas In public areas ensure that the cables attached to the system units, including extension cables, are run and laid out in a neat and tidy manner where they do not interfere and hinder public walk ways. It is recommended that the chairman unit and the interpretation units are connected at the beginning of a trunk line and not at the end. In public areas where connectors and cables could be trampled on, it is strongly suggested to use protective covers according to the existing protection specifications. Due to the directivity of the microphone used in the discussion units, every speaker should face the microphone at a convenient distance when speaking, to achieve both best audibility and intelligibility. 2. Technical rooms It is recommended to meet the following conditions for technical rooms where HCS-3600 central control equipment is housed: Ensure that the area is a dust-free environment. Ensure adequate ventilation. Ensure adequate lighting. But be sure that the lighting does not impede the operator in the control room and the normal system operation. Do not place objects on the top of units. They could fall into vents or could cover them and thus prevent proper cooling of electronic components inside the units. By falling into a unit, objects could cause trouble such as fire and electric shock. To avoid the risk of shock or permanent damage to the system units, do not expose units to rain or moisture. Do not attempt to remove the top cover of the system main units as you will be exposed to a shock hazard. The covers should only be removed by qualified service personnel. If any repair or maintenance is required, contact the TAIDEN service center in your region. Equipment is only for indoor use. Do not expose it to sunlight. WARNING: Damage to the power cable may cause fire or a shock hazard! 3. Interpreter booths Pressure and speed of work at most international conferences imply that interpreters have to take turns and to turn about to keep pace and to ensure a steady flow of smooth interpretation. Therefore every interpreter booth has to have an adequate size to accommodate at least two or three interpreters, depending on the present needs. Following a brief summary, according to the specifications for interpreter booths as drawn up in the ISO standards: In the hall, booths should be set up at the back or sideways. Booths should be elevated to provide an overall, unobstructed direct view of the chairman, the speakers and any other relevant visual aids. A window should be installed at the forefront of the booth across the overall length. An adequate size of the interpretation booth is recommended in order to accommodate the normal activities of the interpreter. Adequate air conditioning, temperature and lighting are required. ISO-4043 Mobile booths for simultaneous translation ISO-2603 Fixed booths for simultaneous translation 4. System operator room In a PC based system, the operator needs a dedicated room to operate the PC and to manage the conference procedure. Generally, the demands on the operator room are the same as on the interpreter booth. By means of a microphone system, the operator should also be connected to a public - address system to remind the participants of operations, such as voting, signing-in, etc. 85

94 5. Ventilation Maintain good ventilation: ventilation holes are provided on top of the main units. Place the units on a hard and level surface to ensure proper ventilation. 6. Cleaning Do not use alcohol, ammonia or petroleum based liquids or abrasive cleaners to clean the equipment. Unplug first and clean with a soft cloth slightly dampened with mild soap and water solution. Assure yourself that the relevant unit is dry before operating it. 7. Storage If the units are not to be used for a long period of time, disconnect the mains supply from all mains supplied units. Store them in a dust-free dry area with adequate ventilation. 86
