* Most of the settings on the computer will be adjusted to match the settings on the unit.

For NJ-CPU-B16, the communication settings above (19200bps/8bit/1bit/odd number) are set by default, so you only need to match the communication port number to which the PLC is connected.

The connection is made directly to the loader port attached to the CPU, and the parameters at the time of connection are fixed, so there are no special items to set on the unit side.
