Host Link Communication method
(selector switch)
Set this to RS-232C.

System setting (Pin 4)
To effect the existing DIP switch settings,
set SW4 to ON.
To effect the existing PC Setup, set pin 4
to OFF.
Note
For CPU Units manufactured before or
during June 1995 (lot No.
jj
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 CPU Units manufactured from July
1995 onward (lot No.
jj
75), 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 CPU Units and 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.)
