4-2. RS-232C Connection
4-2-1. RS-232C Connector
The RS-232C connector is a D-SUB 9-pin connector. The applicable plug is OMRON-
manufactured XM2D-0901 (cover: XM2S-0913 <with inch thread #4-40>) or an
equivalent.
4-2-2. Connector Pin Assignments
4-2-3. Example of Cabling
The above connection diagram shows cabling (as an example) when the PC is DTE (data
terminal equipment). If the other end of the connection is DCE (data circuit-terminating
equipment) such as a modem, use straight type cabling. Also, recheck the connector
shape and signal lines (pin assignments) of the equipment you use before preparation of
cabling.
Applicable plug: D-SUB 9-pin connector
