After verifying both the Converter card and Quantum™
jumper settings, the interconnecting wiring must be done.
Be sure to use 4-conductor shielded communications
cable (two wires for transmit, two for receive). Refer to the
following diagrams for RS-422 and RS-485:

AC422 adapter card. They can be wired to use either RS-
422 or RS-485.
