AIS receiver not sharing GPS over NMEA 2000

Some AIS receivers do not output GPS/GNSS data over NMEA 2000 by default. If Sway Breeze shows no GPS position while your AIS receiver is the only GPS source on the network, this may be the cause.

em-trak B350 / B360

The em-trak B350 and B360 do not output GNSS PGNs over NMEA 2000 by default. You need to enable this manually.

Step 1 — Send the configuration command via proAIS2

Connect your B350/B360 to a computer running the proAIS2 software and send the following command:

$PSMT,0,3,0x2C75B2FA,1,n2kognss -1,0*39

Step 2 — Enable RMC output

In proAIS2, tick the RMC checkbox to enable NMEA 0183 RMC sentence output.

Step 3 — Cycle the power

Power the device off and back on for the changes to take effect.

After this, the B350/B360 will share GPS position data over the NMEA 2000 network and Sway Breeze will be able to use it.
