Connecting to NMEA 0183 (RS232) devices

The AS07-0183 sends positional sentences, in the NMEA 0183-RS232 (single-ended) protocol.
For RS232 interface devices, these wires need to be connected.
NMEA 0183 Green: TX (NMEA OUT)
Black (thick): GND shield
POWER
TAKE CARE: There may be two GND connections on your connecting NMEA 0183-RS232 device.
One is GND for the NMEA Connection, and one is GND for Power.
Ensure you check the above table and your device's documentation carefully before connection.

Connecting to NMEA 0183 (RS422) devices

Although AS07-0183 sends out NMEA 0183 sentences via single end RS232 interface, it also supports
RS422 (differential signal)
or RS232 interface devices, these wires need to be connected.
