Setting up the conference system

Connecting ADN PS power supplies 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 max. of 15 ADN PS power supplies can be used in a conference
system.
̈ Use a system cable to connect the PORT II socket or PORT I socket of the
ADN CU1 central unit to the DATA CU/PS input socket of the first ADN PS
power supply (shorter cables increase the operational reliability, the maximum
length allowed is 80 m).
̈ Use a system cable to connect the DATA PS output socket of the first ADN PS
power supply to the DATA CU/PS input socket of the second ADN PS power
supply.
̈ Repeat these steps for the remaining ADN PS power supplies.
Setting up a large conference system comprising 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 in a cable string to the
ADN PS power supply
The following describes how to connect one cable string to an ADN PS power
supply. If necessary, repeat these steps for additional cable strings and additional
ADN PS power supplies.
̈ Connect the required number of ADN PS power supplies to the ADN CU1 central
unit (see above).
̈ 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
conference unit.
̈ Use a system cable to connect the OUT socket of the first conference unit to
the IN socket of the second conference unit.
̈ Repeat these steps for additional conference units.
̈ If necessary, repeat all steps for a second, third and fourth cable string and
additional ADN PS power supplies.
