1.2 System technology
zMCA-STREAM digital audio processing and
transmission technology
TAIDEN proprietary MCA-STREAM technology is the
essential data transmission technology in the voting
system, e.g. transmitting control and other information
data over a single dedicated 100 Mbps high speed
6-pin cable. Every unit - congress main unit, voting unit
- is equipped with a high performance CPU as the
kernel of the advanced technology infrastructure.
zSystem hardware structure
Voting system hardware is an embedded structure
based on dual high performance CPUs. Even in
stand-alone mode, voting is competent for the
management of electronic voting.
zModular system structure
Any kind of configuration can be set up just by
daisy-chaining Large-Scale Voting System voting units.
The modular system structure of the voting system is
applicable to any kind of conference and provides an
accurate and efficient solution. Additional voting units
can be added when needed. More system functions
are available in connection with a PC and control
software.
zDual main unit hot spare
The voting system hardware systems can be operated
on hot standby with a master and a backup main unit. If
the master main unit fails, the backup unit starts to
operate automatically as master and takes over the
meeting. Thus continuation of the conference is
guaranteed.
zSystem software infrastructure
The voting system software is designed for the
prevalent Client/Server structure. Client and server
communicate with each other by using TCP/IP network
protocol, ensuring both data security and transmission
efficiency. Client and server software can run on the
same computer as well as on different computers in the
same LAN, enabling the operator to manage the
conference more flexibly.
System software imports the hot-spare dual server
structure by using a main server and a back-up server.
While the main server is processing, data are stored
real time on the back-up server to prevent conference
related information from loss in case of a crash of the
main server. As a result, security and reliability of the
conference system are improved vitally.
zDuplicate and backup connection via
“Closed Loop - Daisy Chain” connection
For important meetings, especially those which
consider connection reliability as their leading point,
Large-Scale Voting System adopts advanced “Closed
Loop - Daisy Chain” connection topology, connecting
the last unit in the loop back to the congress main unit.
Therefore, any congress unit in the loop has two
connection paths to the congress main unit. As a result,
breakdown or replacement of a congress unit and
connection failure of a cable will not influence other
congress units. As such the system features the
advantages of a daisy chain connection system with its
simpleness of cabling as well as the improvement of
the system reliability through duplicate and backup
connection functions. In Large-Scale Voting System,
only the congress main unit supports “Closed Loop -
Daisy Chain” connection topology, and only one ring
connection allows.
zAdvanced TCP/IP communication protocol in
PC control
In a PC controlled system, the congress main unit 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 meters. 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, computer science and communication
technology. 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.

4
zCMU and EMU
The congress main unit forms the core of the entire
conference system. It provides power supply to all
voting units and serves as key component to link
system hardware to application software. One CMU
has two (6P-DIN) trunk-line cable outlets, If more
congress units are needed, additional extension main
units (EMU) HCS-8300ME are required. Each EMU
has four (6P-DIN) trunk-line cable outlets. Large-Scale
Voting System maximum capacity: 4096 voting units.
zVoting units
Voting units are units used by participants to contribute
to a conference and include: voting chairman units,
voting delegate units. The voting unit has voting facility
and graphic 256x32 LCD with back-lighting. Depending
on the option, voting units can be divided into tabletop,
flush-mounted. Each style consists of various products,
which enriches significantly users’ choices.
Low power consumption design is adopted for voting
units, convenient for wiring and installation. All voting
units of the voting system are supplied by the main
unit’s 6P-DIN interface. Since the power capacity of the
6P-DIN interface is limited, it must be ensured during
installation that the added up values of a) the total
power consumption of all congress units connected in
each path and b) the power loss in extension cables do
in no case exceed the maximum possible value
delivered by each 6P-DIN interface. Otherwise the
system will not work properly or automatic protection
will be triggered (see 4.2 connection principles).
zApplication software
Large-Scale Voting System 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 application software
integrated into the Large-Scale Voting System, the
operator manages centrally all aspects of the
conference. The operation turns out to be easy and
efficient.
The voting system application software is modular
software with various functional modules: System
Setup Management Module, Voting Management
Module, Multi-user Conference Control Management
Module, Dual PC Server Hot Spare Module, Agenda
Control Module, Dual System Main Unit Hot Spare
Module, etc.
zInstallation and transportation
Easy installation is another vital feature of Large-Scale
Voting System. All voting units are equipped with a
1.5-meter-6P-DIN cable (with a male connector) and a
0.6-meter- 6P-DIN cable (with a female connector). All
voting units are connected together in a daisy chain
configuration and connected to the main unit by the
dedicated extension cable.

2.2 Installation
The CMU can be fixed in a standard 19-inch cabinet. The
CMU is equipped with a pair of fixing brackets ①. First
unscrew the lateral screws ②from the housing. Then
fasten the brackets with these screws and put the CMU
in the cabinet. Finally fix the four holes ③up with
screws.
Figure 2.3 Installation of the CMU
In addition, 1U metal stripes are included as
decoration to be installed between the CMUs in the
cabinet. It is also good for the ventilation and cooling off.
Fix up the four holes ③with screws.

2.3 Connection
HCS-4100MC/50 has 2 outlet (6P-DIN) trunk-line cable
sockets for connecting to voting units. Voting units are
equipped with a cable with a standard 6P-DIN male
connector.
When connecting the CMU to the voting units, just
connect the male connector of the first unit to the
socket of the CMU.
For a longer distance between the voting unit and the
CMU/EMU, a CPL6PS extension cable can be used.
One end of this cable is equipped with a 6P-DIN male
connector; the opposite end is equipped with a female
connector. Just connect the female connector of the
cable to the voting unit, and connect the male
connector to the output of the main unit.
Figure 2.5 Voting unit connected to the CMU or the EMU
For “daisy chain - closed loop” connection, just connect
the last voting unit back to the CMU via a CBL6PP
extension cable (both ends of this cable are equipped
with a 6P-DIN male connector). In Large-Scale Voting
System, the congress main unit can realize a “Closed
Loop - Daisy Chain” connection, but only one –
extension units do not offer this feature.
Figure 2.6 “Daisy chain – closed loop” connection
topology
One HCS-4100MC/50 contains 2x 6P-DIN outlet
trunk-line cable connectors, and each outlet connector
can output 60W. Since the power capacity of a 6P-DIN
interface is limited, it must be ensured that, during the
installation, the sum of the total power consumption of
all the congress units connected to every single
6P-DIN interface plus the power loss in the extension
cables does not surpass the power limit of each
6P-DIN interface. Otherwise the system will not work
properly or automatic protection will occur (see 4.2
connection principles).
