CMU 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.

Voting 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).

Application 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.

Installation 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.
