To connect the A200 over USB an isolated NMEA 0183 (RS422) - USB adaptor will need to be installed with the supplied 18-way cable, either via the External Display or Pilot ports, or the LR/DGNSS port if it's configured as External Display 2.
Wiring information for each port is detailed in the A200 user manual and quick start guide. Other manufacturers may use different signal names, however the following general guidelines will apply when connecting the adaptor:
- positive signals should be connected together
- negative signals should be connected together
- transmit signals should be connected to receive signals and
vice versa
