Setting up a small conference system with only the central unit
For a small conference system, you do not require ADN PS power supplies.
Connecting conference units
connected in a cable string to the
ADN CU1 central unit
The following describes how to connect one cable string to the ADN CU1 central
unit. If necessary, repeat these steps for a second cable string.
왘 Use a system cable to connect the PORT II socket or PORT I socket of the
ADN CU1 central unit to the IN socket of the first conference 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 additional conference units.
왘 If necessary, repeat all steps for a second cable string.
Please note that there is a limited number of approx. 15-20 conference
units per cable string due to the voltage drop on the cable string (see
page 15).
