Optional System Components
Power Supply – The 24-Crosspoint Remote Aux panel power supply
( Figure 41 ) should be securely fastened to a horizontal surface or attached
to a support inside the equipment rack. Verify that the power supply cord
reaches the 24-Crosspoint Remote Aux Control panel and the AC source.

Communications Bus – The communications bus cable connector shipped with
each panel must be attached to the supplied cable or a user fabricated cable
(refer to
Figure 42 ). The supplied cable is 50 m (164 ft) long and has a pre-
wired 9-pin D connector on one end.
If fabricating a cable, use a shielded twisted pair cable such as Belden 8451
and refer to
Table 8 for wiring connections. The total length of cable in a 24-
Crosspoint Remote Aux panel daisy-chain cannot exceed 320 m (1000 ft).
Allow enough cable to reach each control panel connector, plus about 1 m
(approximately 3 ft) extra.
