A Standard System Protocol
R-124
CJ-series Serial Communications Units Operation Manual for NJ-series CPU Unit(W494)
Operand and Send/Receive Data Word Settings of PMCR(260)
Setting Example
When send data is THIS IS SAMPLE.
A maximum of 200 bytes (including the CR) can be received. When the received data is RETURN
OK, the content stored in the receive words is as follows:

modem settings.
The hang up command (to disconnect the line) can be executed using sequence No. 555. No setting is
necessary for this sequence.
