* 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
.

* When HUB is using, Straight cable should be used.
Ex) Straight Cable Wiring: Connect 1:1 according to the wiring diagram above.
* In case of do not using HUB, do not use HUB, when it is connected directly, Cross Cable should be used.
Ex) Cross Cable Wiring: In the above wiring diagram, TD+ and RD+ are changed, and TD- and RD- are exchanged.
