* Make sure that for RS-232C communication line, RD and SD cross each other with a twisted pair cable. SG
should be directly connected.
* For RS-422 and 485 communication line, RDA and RDB, and SDA and SDB should be a twisted pair cable,
respectively. Connect the signal ground with that of an external device. It can improve noise immunity.
* Do not run RS-232C, 422, and 485 at the same time.
* Do not use the shield wire of the communication line for the signal ground. It can lead to communication
failure.
