For wiring, see the Operation Guide or User's Manual. A maximum of 31 serial devices
are connectable. Set a communication address (02 to 99) different from each other for
each device.
Note
When Ethernet-serial gateway function is used, do not set the communication address '1' for
the RS-485 communication serial devices connected to the Ethernet-connected UT75A/UT55A/
UT35A/UP55A/UP35A.
