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 connecting cables and ports used, in the way shown in
the following table. For details, refer to the CPM2C Operation Manual (W356).

With C-series CQM1H PCs, in addition to the CPU Unit's RS-232C port and
peripheral port, the NT30/NT30C can also be connected to port 1 of the Serial
Communications Board. Provide an RS-232C, 9-pin connecting cable.
For details of specifications and mounting methods for Serial Communications
Boards that can be used for connection, refer to the CQM1H Serial Communica-
tions Board Operation Manual (W365).
With CS1-series PCs, in addition to the CPU Unit's RS-232C port and peripheral
port, the NT30/NT30C can also be connected to the Serial Communications
Board and Serial Communications Unit. Provide an RS-232C, 9-pin connecting
cable.
For details of specifications and mounting methods for Serial Communications
Boards and Units that can be used for connection, refer to the CS1-series Serial
Communications Boards/Unit Operation Manual (W336).
When a connector cable of 5 m or longer is required, please make the cable.
However, note that the maximum transmission distance is 15 m.
To make a connector cable, refer to the appendix Making the Cable for Connec-
tion to the PC (page 271).
Communications distances not possible with RS-232C specifications can be
achieved using RS-422A communications (RS-485 communications cannot be
used).
When the NT30/30C and PC are connected to each other, set the conditions at
the PC Host Link Unit or the CPU Unit as given in the table below.
