Structuring the SDC 8200 system
46
왘 Calculate the maximum cable length using the “Powercalc.exe” soft-
ware (see “Determining maximum cable lengths” on page 47) in order
to ensure that all consoles are supplied with sufficient voltage.
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 con-
soles, you can interconnect a total of 12 central units. The additional cen-
tral units are connected as “slaves” to the central unit configured as “mas-
ter”. 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 in master/slave mode (SDC 8200 CU
central units only)” on page 54).
왘 Calculate the maximum cable length using the “Powercalc.exe” soft-
ware (see “Determining maximum cable lengths” on page 47) 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.
