6.9 Network Connection and Remote Communications via CXCM
The Cordex system can be set up, monitored and tested via ETHERNET 10/100 Base-T serial data connection or
with a RS-232 serial data connection. The communication protocol supports a web interface.
NOTE: Pinouts are shown in customer connections drawing 030-713-08.
Some standard scenarios are described below:
6.9.1 Ethernet Port for Network Connection (Standard Network Cable)
The Ethernet port is designed for CXCM connection to a user supplied network (TCP/IP secured by user) via a
rear panel RJ-45 jack. Connect to the Cordex shelf using a standard network cable.
6.9.2 Ethernet Port for Local Connection (Crossover Cable)
Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard network
crossover cable.
6.9.3 RS-232 Serial (Craft) Port for Local Connection
Local access to the CXCM is possible through the front panel RS-232 serial port using a null modem cable:

6.10 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.
