I/O port selector switch
C-series C200HS, C200HX/HG/HE(-Z)E, CPM1, CPM2A, CPM2C, CQM1, CQM1H CPU Units, SRM1
The connection method depends upon the model of PLC being used, as shown in the
following table.

PLC Setup Area Settings
When connecting to a C200HS, C200HX/HG/HE(-Z)E, CPM1, CPM2A, CPM2C, CQM1, or
CQM1H CPU Unit, or SRM1, set the following communications conditions for the PLC Setup
area.

• I/O port selection (selector switch)
Set this to RS-232C.
• System setting (DIP SW4)
To effect the existing DIP switch
settings, set SW4 to ON.
To effect the existing PC Setup, set
SW4 to OFF.
Note
For CPUs manufactured before or
during June 1995 (lot No. @@ 65), the
existing DIP switch settings differ from
the existing PC Setup as follows.
- DIP switch settings:
2,400 bps, 1 stop bit, even parity, 7
bit data length
- PC Setup:
9,600 bps, 2 stop bits, even parity, 7
bit data length
For CPUs manufactured from July 1995
onward (lot No. @@ 75), the stipulated
values in the DIP switch settings also
are 9,600 bps and 2 stop bits.
Connect to the CPU Unit's built-in RS-232C port.
• Connect to the CPU Unit's built-in RS-232C port.
• Connect to one of the RS-232C ports (port A or port B) on a Serial
Communications Board.
• Connect to the CPU Unit's built-in RS-232C port.
• Connect to the peripheral port through a CS1W-CN118
Connecting Cable.
• Connect to the RS-232C port (port 1) on a Serial Communications
Board.
Connect to the peripheral port through a CPM1-CIF01
RS-232C Adapter.
• Connect to the CPU Unit's built-in RS-232C port.
• Connect to the peripheral port through a CPM1-CIF01 RS-232C
Adapter.
Connect to the CPU Unit's RS-232C port or the peripheral
port through a Connecting Cable (CPM2C-CN111,
CS1W-CN118, or CS1W-CN114).
(The CPM2C-CN111 splits the Unit's communications port into
an RS-232C port and a peripheral port. A CPM1-CIF01
RS-232C Adapter is also required to connect to this peripheral
port.)
Host link mode
Set the same baud rate as set at the NS-series PT (See note.)
