  • Page 16: Connecting

    Connecting RS422/485 (X27) interface of the communication module The RS422/485 (X27) interface is a differential voltage interface and is used for serial data transmission. The inputs and outputs are not isolated from each other. The inputs and outputs are electrically isolated from the backplane bus. Terminal assignment Plug the connecting cable into the 15-pin D-sub socket behind the front flap of the communications module.
