Chapter 5 System connection and basic setup procedure
5.1 System connection
HCS-8300 PMCS has a simple and reasonable structure
with high extendibility in hardware. The system
installation is simple and quick and does not need
special training. Daisy-chain connection is adopted
between congress units as well as to CMU via dedicated
6-pin cable.
TCP/IP protocol is adopted for Ethernet connection
between CMU and PC. As a result remote control,
remote diagnosis and remote update can be achieved.
Application software for client and server can run on one
computer or on different computers in the same LAN.
The operator is able to control the progress of the
meeting flexibly.
In this chapter, the connections of HCS-8300 PMCS are
introduced by diagrams and examples.
5.1.1 Connection principles
In HCS-8300 PMCS system power is provided by
HCS-8300M CMU (EMU) or HCS-8300EMS for all
congress units (except for HCS-8338 and HCS-8348
series). Thus, the total number of system units in any
installation is limited by the maximum power handling
capacity and control capacity of the HCS-8300M CMU
(EMU) or HCS-8300EMS. 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. Refer to
table 5.1.1, table 5.1.2 for maximum load capability.
HCS-8338 and HCS-8348 series Paperless Multimedia
Congress Terminals are provided power by the
HCS-8300PM/PM2 Power Supply Unit with 2P aviation
slots. Refer to table 5.1.3 for maxminum load capability.
By cascade connecting extension main units
(HCS-8300ME(/FS)) or extension units (HCS-8300MES),
the HCS-8300 system can accommodate 4096
discussion/voting units (by using system application
software up to 100 chairman units can be connected but
only 1 chairman unit has control facilities), 378
interpreter units (63 interpreter booths, 6 in each), an
unlimited quantity of channel selectors, and provide 64
language channels (including floor language)
simultaneous interpretation.
Note:

The added up cable lengths between a main
unit and the most remote congress unit must
not exceed 250 m;

The length of an individual extension cable
must not exceed 80 meters. Otherwise it will
affect the signal quality. In case the length
exceeds 80 m, HCS-4352T/50 is needed;

The extension cable between the main
unit/extension unit and the first congress unit
is carrying the maximum possible current.
However, the cable length between the two
last congress units is nearly insignificant
because this cable only carries the current for
one unit.
