NMEA 0183 devices can receive AIS data when connected to the M1 I/O (Sensors GPIO / NMEA 0183) expansion port.

The NMEA Baud rate can be changed via the Cortex Onboard™ App or from the H1 handset.

Using the Cortex Onboard App

1. Select Menu ()
2. Settings
3. Device Settings
4. Networks
5. NMEA 0183...
6. Baud rate (select)

Using the Cortex™ handset

1. Select Main Menu ()
2. Touch on the wrench icon () to open the Configuration Menu.
3. Networks
4. 0183 (NMEA 0183)
5. Baud In
6. Baud out

HINT - AIS output requires a minimum of 38400 Baud rate.

Note - When connecting the M1 to NMEA 0183 devices, connect 0183 Common (Black) to the vessel's negative bus. This is to ensure a satisfactory grounding as the NMEA 0183 network of the M1 is isolated.
