Yes, with a few exceptions. The RS-422, RS-485 specification does not define a connector pin out. However, Sealevel adheres to it’s own standard for RS-422 and RS-485 pin outs, for both DB9 and DB25 connectors, across the entire product line (except a few older ISA products). Sealevel RS-422, RS-485 products adhere to the industry standard RS-530 specification meaning that standard RS-530 cables for connecting DTE to DCE devices can be used. Sealevel offers several optional cables and terminal blocks that can simplify field wiring and are available on the accessories page. If using an RS-530 cable from another manufacturer, it should be confirmed that the cable is constructed with a shielded, twisted pair cable and that the signals are paired correctly.
