Putting the conference system into operation
58 | ADN Digital Conference System
Setting up a large wired conference system with ADN PS power supplies
connected to the ADN CU1 central unit
For conference systems comprising more than 40 conference units or when the
conference units are connected in a redundant ring topology, you require ADN PS
power supplies. A maximum of 15 ADN PS power supplies can be used in a confer-
ence system.
왘 Use a system cable to connect the PORT II socket or PORT I socket of the
ADN
C
U1 central unit to the DATA CU/PS input socket of the first ADN PS
power supply (the maximum cable length allowed is 50 m).
왘 Use a system cable to connect the DATA PS output socket of the first ADN PS
power supply to t
he DATA CU/PS input socket of the second ADN PS power
supply.
왘 Repeat these steps for the rema
ini
ng ADN PS power supplies.
Setting up a large conference system co
mprising ADN PS power supplies and
conference units connected in cable strings
For large conference systems with up to 400 conference units, you require ADN PS
power supplies. When the conference units are connected in simple strings, one
ADN PS power supply can power approx. 60-70 conference units.
Connecting conference units
connected i
n a cable string to the
ADN PS power supply
The following describes how to connect one cable string to an ADN PS power sup-
ply. If necessary, repeat these steps for additional cable strings and additional
ADN PS power supplies.
왘 Connect the required number of ADN PS power supplies to the ADN CU1 central
unit (see page 58).
왘 Use a system cable to connect the PORT I or PORT II socket – output 1 / or
2 / – of the ADN PS power supply to the IN socket of the first confer-
ence unit.
왘 Use a system cable to connect the OUT socket of the first conference unit to
the IN socket of the second conference unit.
왘 Repeat these steps for additi
on
al conference units.
왘 If necessary, repeat all steps for a second,
third or fourth cable string and for
additional ADN PS power supplies.
