Connecting the compass to your application

2.1 Compass to a NMEA-0183 instrument

The hardware on which the NMEA-0183 standard is based on is a balanced serial

protocol called RS422. This means that two wires are need for send and two for

receive.

Note that the GND wire is used for the current return path. This might be

shared with the NMEA- wire in some installations.

2.2 Compass to a PC serial port

In many cases the wires can be joined directly as shown in Fig 2.

Alternatively use the Autonnic A3036 serial interface unit.
