Connecting to the Host’s RS-422A/485 Port
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.
