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 8 or 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).
For information on how to mount the central unit into a 19” rack, refer to
the detailed instruction manual.
