Connecting to a CPM2C
Only the CPM2C PCs do not have the same kind of port connectors found on
CS/CJ-series PCs. The CPM2C’s communication 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 connec
-
tions,
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.
