To connect to NMEA 0183
NMEA 0183 devices can receive AIS data when connected to the Cortex Hub 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
AIS output requires a minimum of 38400 Baud rate.
When connecting the Cortex Hub 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 Cortex Hub is isolated.
