Using RS-232C
Set DIP switch pin 4 or 5 of the CPU Unit according to the port to which the PT is connected,
as follows:
Peripheral port
Mainly connected to a
Programming Device.
(Can be connected to
an RS-232C device.)
RS-232C port
Mainly connected to
an RS-232C device.
(Can be connected to
a computer running
the CX-Programmer.

PLC Setup Area
• Using RS-232C
When connecting the PT to a CJ-series CPU Unit, set the communications conditions in the
Setup according to the communications port used, as follows:
PLC
Using the CJ1G/H-H, CJ1G, or CJ1M Built-in RS-232C Port
Address
160
161
166
Note 1. Set the baud rate to a numeric value between 0000 to 0009 Hex. (The setting is the same for
2. When using a 1:N connection, set the value for @ to 1 or higher.
For example, to connect PTs with unit numbers 0, and 2 to 5 to the built-in RS-232C port in
1:N NT Links, set address 160 to 8200 Hex, and address 166 to 0005 Hex.
Set whether the PLC Setup is set directly from the Programming Device (Programming Con-
sole) or created by the Support Software (CX-Programmer) and transferred to the CPU Unit.
Refer to the SYSMAC CJ Series Operation Manual (W393) for information on the PLC Setup.

When setting a 1:N NT Link in the CX-Programmer, set the baud rate to 38,400 bps.
DIP switch (inside battery compartment)
Turn ON pin 4 when connecting the PT to
the peripheral port (to use the
communications settings in the PLC
Setup).
Turn ON pin 5 when connecting the PT to
the RS-232C port (to use the
communications settings in the PLC
Setup).
