Each CCM appliance serial port has an RJ-45 connector for attaching a serial device. Table B.1 
lists the pin assignments.

Modular adaptors are available to convert RJ-45 modular jacks to standard pinout configurations. 
Adaptors are available for use with:
•

CAT 5 cable (and CAT 6 cable for CCM4850 appliances).

•

Serial reversing cable. Reversing adaptors and cables are recommended for distances greater 
than 100 feet.

Table B.2 lists the adaptors available for use with CAT 5 and CAT 6 cable.
