Structuring the conference system
The ADN conference system is suitable for conferences with up to 400 conference
units. For safe operation of the conference system, make sure that all conference
units are supplied with a voltage of at least 35 V! The voltage supplied depends on
the number of connected conference units and on the cable lengths. The standard
cable length between the central unit or power supply and the first conference unit
is 80 m max. and the standard cable length between the individual conference
units is 2 to 5 m.
If these cable lengths are observed, safe operation of conference systems with the
following number of conference units is ensured:
small conference systems comprising only an ADN CU1 central unit
30-40 conference units connected in simple strings
large conference systems comprising an ADN CU1 central unit and a max. of
15 ADN PS power supplies
max. 400 conference units connected in simple strings or in ring topology
per ADN PS power supply
60-70 conference units connected in simple strings
30-40 conference units connected in ring topology
If cable lengths are shorter, it might be that more conference units can be used.
ADN D1 delegate units and ADN C1 chairperson units can be combined in an
arbitrary order. The number of chairperson units, however, is limited to 10 max. per
conference system. All components of the conference system are interconnected
using SDC CBL RJ-45 system cables.
Small conference system with simple cabling
For small conference systems with approx. 30-40 conference units, you require one
ADN CU1 central unit for controlling the conference. The conference units are
interconnected in two cable strings which are directly connected to the central unit.
