To enable GPS data output from your B100:
Download the aisb.cfg file to a blank SD card (any card up to 32GB is fine).
Turn off the B100, insert the SD card, and power it back on.
Wait for the LEDs to stop flashing—then switch the unit off and on again.
Open our configuration software, ProAIS2 and choose the GPS sentences you want to send out, and click “Write Configuration.”
That’s it! Your B100 will now output GPS data via both high and low speed NMEA ports.
Don’t worry—this won’t change your vessel details (MMSI, name, etc.).
