I/O port selection (selector switch)
Set this to RS-232C.
I/O port selector switch
•
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.

values in the DIP switch settings also
are 9,600 bps and 2 stop bits.
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 model
Connection method
C200HS, CQM1
Connect to the CPU Unit’s built-in RS-232C port.
C200HX/HG/HE(-Z)E
•
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.
CQM1H
•
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.
CPM1
Connect to the peripheral port through a CPM1-CIF01
RS-232C Adapter.
CPM2A, SRM1
•
Connect to the CPU Unit’s built-in RS-232C port.
•
Connect to the peripheral port through a CPM1-CIF01 RS-232C
Adapter.
CPM2C
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.)
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.
