NMEA 0183 devices can receive AIS data when connected to the
M1 I/O (Sensors GPIO / NMEA 0183) expansion port.
- The NMEA sentences supported are included on page 26.
The NMEA Baud rate can be changed via the Cortex Onboard App
or from the H1 handset.
Cortex Onboard App:
> Menu (
) > Settings > Device Settings
> Networks > NMEA 0183... > Baud rate (select)
Cortex handset:
> Main Menu (
). Touch on the wrench icon ( ) to open
the Configuration Menu.
> Networks
> 0183 (NMEA 0183)
> Baud In >
> 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.
