Structuring the SDC 8200 system
46
Expansion stage (3): several interconnected SDC 8200 CU central units
with up to 1024 consoles
For larger conference and interpretation systems with up to 1024
consoles, you can interconnect a total of 12 central units. The additional
central units are connected as “slaves” to the central unit configured as
“master”. If the conference and interpretation system is to be PC
controlled, the PC must be connected to the “master” central unit.
To set up a conference system with several central units, you first have to
interconnect the consoles in cable strings and then connect the cable
strings to the central units. Finally, you interconnect the central units (see
“Interconnecting several central units (SDC 8200 CU central unit only)” on
page 54).
왘
Calculate the maximum cable length using the “Powercalc.exe”
software (see “Determining maximum cable lengths” on page 46) in
order to ensure that all consoles are supplied with sufficient voltage.
The maximum length of the system cables used for interconnecting the
central units must not exceed 10 m.
Determining maximum cable lengths
In the preceding examples, the standard length of “3 m” is always given
for the system cables between the conference consoles. However, it is no
problem to use other cable lengths or cables of differing lengths within the
same string.
However, if you wish to use longer cables, make sure that all consoles –
including the last one in a string – are supplied with a voltage of at least
30 V!
