Configure the CAN COM port

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2

Bind a CAN communication port to a J1939 node (see J1939CONFIG command) and specify the CAN protocol, PGN, priority and address for messages transmitted and received over the CCOM port.

The SMART2 requires a "-C" model to use this command.

Message ID: 1902

Abbreviated ASCII Syntax:

CCOMCONFIG port node protocol [pgn [priority [address]]]

Factory Default:

CCOMCONFIG ccom1 node1 J1939 61184 7 fe

CCOMCONFIG ccom2 node2 J1939 61184 7 fe

CCOMCONFIG ccom3 node1 J1939 126720 7 fe

CCOMCONFIG ccom4 none none 0 0 0

CCOMCONFIG ccom5 none none 0 0 0

CCOMCONFIG ccom6 none none 0 0 0
