All ports are serial, RS-422, operating at up to 1 Mb/s. The interface is RJ-45. Each port has the
following pinout:
A port can be configured as “controlling” or “controlled” or variants (dynamic, master, slave).
That is, the definition of the port can be reversed (Tx becomes Rx and vice versa) either during
configuration or during operation.
Refer to the CRSC User’s Guide for port configuration information.
Refer to Cabling on page 181 for configuration information.
Control Panels
The behavior of control panels in stand-alone systems is very different from the behavior of
control panels in CRSC systems. That is because CRSC remote panel operation is configurable
and stand-alone panels are not configurable.
A “captive” panel in a CRSC network is a stand-alone panel and therefore behaves unlike the
remote panels in the CRSC network.
