Use DIP switch pins 1 and 2 on the CPU Unit to set the same baud rate as the
Controller Link Support Software.
DIP switch pins
Baud rate
1 2
OFF OFF 50 Kbps (see note)
ON OFF 19,200 bps
OFF ON 9,600 bps
ON ON 4,800 bps
Note The baud rate cannot be set to 50 kbps for the Controller Link Support
Software.
CQM1H PCs
Connecting to Peripheral Port
Use one of the following methods when connecting to the peripheral port on the
CPU Unit.
a) Set DIP switch pins 5 and 7 to ON, and set the baud rate for the Controller
Link Support Software to 9,600 bps.
b) Set DIP switch pin 5 to OFF and pin 7 to ON, and set the PC Setup word
DM 6650 (peripheral port settings) to 0000 Hex (standard setting). Set
the baud rate for the Controller Link Support Software to 9,600 bps.
c) Set DIP switch pin 5 to OFF and pin 7 to ON, and set the PC Setup word
DM 6650 (peripheral port settings) to 0001 Hex (settings according to
DM 6651). Set the communications settings (DM 6651: peripheral port
settings) to the same settings as the Controller Link Support Software.
Set the baud rate for the Controller Link Support Software to a value in
the range 2,400 to 19,200 bps.
Connecting to RS-232C Port
Peripheral bus connection to the RS-232C port is not possible.
Host Link
If the Controller Link Support Software is to communicate with a PC via a Host
Link, the PC must be set to the same communications parameters as the Con-
troller Link Support Software.
Note See 5-14-3 Setting PC Communications (on page 137) in 5-14 System Setup to
set the communications parameters for the Controller Link Support Software.
CS1-series PCs
Connecting to Peripheral Port
When connecting to the peripheral port on the CPU Unit, set DIP switch pin 5 to
ON and make the PC Setup settings for the CPU Unit using CX-Programmer.
Select the peripheral port and set the serial communications mode to Host Link,
and make the same communications settings as the Controller Link Support
Software.
Connecting to RS-232C Port
When connecting to the RS-232C port on the CPU Unit, set DIP switch pin 5 to
OFF and make the PC Setup settings for the CPU Unit using CX-Programmer.
CVM1 and CV-series PCs
