The Cygnus ROV mountable systems utilise RS422 communications protocol

Note:
RS-485 meets all the RS-422 specifications, therfore RS-485 drivers can be used in RS-422 applications.
The opposite, however, is not true. The common-mode output range for RS-485 drivers is -7V to +12V, whereas the common-mode range for RS-422 drivers is only ±3V. The minimum receiver-input resistance is 4kW for RS-422 drivers and 12kW for RS-485 drivers.
