4.10.1 Ethernet Port for Network Connection
The Ethernet port is designed for CXCM connection to a user supplied network via an RJ-45 jack. Connect to the
Cordex shelf using a standard network cable. Pinouts are shown in drawing 030-704-08.

4.11 CXCM Battery –48V Connection
The Battery -48V should be connected at the battery system voltage terminal for CXCM reference when a battery
disconnect device is used. It is critical to CXCM operation as it ensures a source of power to the CXCM should
the disconnect device open the circuit. A 1/4” spade (quick connect) connector is provided on the CXCM portion
of the shelf backplane. #18 AWG wire is recommended. Note: this connection is factory-equipped for List 87.
4.12 Alarm and Signal Wiring Connections for CXCM
For terminal block connections, the recommended wire sizes are 0.823 to 0.129mm
2
(#18 to #26 AWG) for the
temperature range of 0 to 50 deg. C (as per UL/CSA).
For insulation displacement receptacles, the recommended wire size is 0.823mm 2 (#18 AWG).
CAUTION: to reduce risk of fire, use only 0.129mm 2 (#26 AWG) or larger wire.
