Connecting the NT30/30C to a C-series CPM2C
The CPM2C has only one connector, which is the same shape as the CS1-series
peripheral port. The signals in this connector, however, are divided internally into
those for the RS-232C port and those for the peripheral port. Therefore, when
using the CPM2C, make separate settings for the RS-232C port and the periph-
eral port according to the conversion cables and ports used, in the way shown in
the following table. For details, refer to the CPM2C Operation Manual (W356).
