Important Notes
  • DTR/DSR Handshaking is not available on RS-422/485 devices.
  • For RS-422 FULL Duplex Communications, please note the pin outs above.
  • To achieve RS-485 Half Duplex Communications, using two wires for communication, Pins 1 and 6 must be shorted and 2 and 7 must also be physically shorted. This can be done by using the on-board jumpers or via the on-board Multi-plex jumpers.
  • Once your wiring is setup, you will also need to set the card to FULL or HALF Duplex mode in the software. For further details, see RS-422/485 Settings and Information.
