• Using RS-232C
When connecting the PT to a CJ-series CPU Unit, set the communications conditions in the
PLC Setup according to the communications port used, as follows:
Using the CJ1G/H-H, CJ1G, or CJ1M, Built-in RS-232C Port
Address Write value Settings
160 8200 1:N NT Link Mode
161 000A Baud rate (high-speed)
166
000@ @: Largest unit number (1 to 7) of connected PTs. (See note.)
Note: When connecting a single Unit in a 1:N connection, set the value of @ 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 to be set directly from the Programming Device (Programming
