* Be sure to connect the RD and SD to the RS-232C communication line by crossing each other with a Twisted Pair Cable.
Please connect SG directly.
* SG must be connected directly.
*
RS-422/485 communication line must use RDA and RDB as Twisted Pair Cable, SDA and SDB as Twisted Pair
Cable
.
*
Do not use shield wire of communication line as signal ground. It may cause communication failure
.
