Setting up the conference system

Connecting the conference units to the central unit

You can connect up to 15 conference units to each of the central unit’s connection sockets PORT II 8or PORT I 9. The maximum number of conference units that can be used in one cable string depends on the overall cable length connected to a port (see page 7).

The following describes the procedure for one cable string. If necessary, repeat these steps for a second cable string.

￿Place the conference units at the corresponding seats.

￿Put out a sufficient number of system cables in the required lengths.

￿If necessary, calculate the maximum length of the cable string in order to ensure that all conference units connected in the string are supplied with a voltage of at least 35 V (see page 7).
