GNSS Compass RTK (2-pin) RS-422 Connection

The GNSS Compass modules drive longer cable lengths than can be done reliably with TTL-level serial signals. The ROVL-ethernet PC board is set up to accommodate this.

The RTK (2-pin) connections use RS-422 signaling to drive the required line lengths. The Base unit transmits only and the Rover unit receives only.

Note the pinout of the Rover cable 2-pin connection is reversed from that of the Base.
