RS-232C
I/O port selector switch
RS-422A
@ 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. jj65), 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. jj75), the stipulated
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 CPUs, SRM1
The connection method depends upon the model of PC being used, as shown in
the following table.
PC 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 Commu-
nications 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 Communication Port
into a RS-232C port and a peripheral port. A CPM1-CIF01
RS-232C Adapter is also required to connect to this
peripheral port.)
