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 8 or PORT I socket 9 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 A 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

The following describes how to connect one cable string to an ADN PS power

connected in a cable string to the

supply. If necessary, repeat these steps for additional cable strings and additional

ADN PS power supply

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 6/8 or

 

2 7/9 – 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.
