Chapter 5 System connection and basic setup procedure
5.1 System connection
HCS-4800 series fully digital congress system 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 8-pin cable or converter 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-4800 series fully
digital congress system are introduced by diagrams and
examples.
5.1.1 Connection principles
In HCS-4800 series fully digital congress system, power
is provided by HCS-4800M or HCS-8600MEA or
HCS-8600EMS for all congress units. Thus, the total
number of system units in any installation is limited by
the maximum power handling capacity and control
capacity of the HCS-4800M or HCS-8600MEA or
HCS-8600EMS. It must be ensured that, during the
installation, the sum of the total power consumption of all
the congress units connected to every single 8P-DIN
interface plus the power loss in the extension cables
does not surpass the power limit of each 8P-DIN
interface. Otherwise the system will not work properly or
automatic protection will occur. Refer to table 5.1.1 for
maximum load capability.
By cascade connecting extension main units
(HCS-8600MEA series) or extension units
(HCS-8600MES),
the
HCS-8600
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-4852T(N) is needed; The length of an
individual extension cable following HCS-4852T(N)
must not exceed 80 meters;
When the extension cable is longer than 60 meters,
please be sure to replace the cat5e cable with
braided shield;
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.
