Connecting to the RS-232C Port at the Host Section 4-1

Connecting to a CPM2C

The CPM2C PLCs do not have the same kind of port connectors found on CS/ CJ-series PLCs. The CPM2C’s communications port handles both RS-232C and peripheral port connections which are divided internally. Therefore, when using the CPM2C, it is necessary to select RS-232C or peripheral port con- nections, according to the kind of cable and port (on the cable) used, as shown in the following table. Refer to the CPM2C Operation Manual for more details.
