Check that the power supply is connected correctly.
Check that the power supply is a 12V or 24V supply.
The red error LED indicator is flashing
There may be a problem with the VHF antenna system. This can be confirmed using the configuration tools. If the 'High VSWR' alarm is active, check for the following:
Faulty VHF antenna/cable/connectors.
Poor connection at the VHF antenna/cable/connectors.
Suitability of the VHF antenna. For B921/B922/B951/B952 an antenna tuned for AIS at 162MHz is recommended. For variants with a splitter (B923/B924/B953/B954) an antenna tuned to operate across the frequency range 156MHz to 162MHz is required.
VHF antenna location (ensure that is isn't mounted near other transmitting antennas or sources of interference, metal structures, or other obstructions).
Check that the unit is configured with a valid MMSI number. This can be confirmed using the Configuration tools.
Check that the GPS antenna has a stable position fix. This can be confirmed using the configuration tools.
Check that the power supply is within 9.6 - 31.2V. This can be confirmed using the configuration tools.
The amber LED indicator is flashing continuously
The amber LED indicator flashes while the transceiver searches for a position fix. If it takes longer than a minute you can check the performance of the GPS antenna by using the configuration tools.
No data is being received by the chart plotter
Check that the signal wires are connected correctly.
Check that the baud rate matches both the transceiver and the chart plotter.
Confirm that other vessels are within radio range and that they are displayed on the Other Vessels tab of proAIS2 or CONNECTAIS.
My vessel name isn't being received by other vessels
Static data (containing vessel name, call sign, etc) is transmitted every 6 minutes so it may take a few transmissions before all the vessel data is displayed.
Position reports contain critical data like position, MMSI number, vessel speed, etc and these are transmitted more regularly.
I can't establish a connection using Wi-Fi or Bluetooth
Check that the transceiver is powered by 12 - 24V.
Check the configuration parameters using proAIS2.
Check that there are no obstructions between the transceiver and mobile device.
Check that there are no sources of interference nearby.
Check that the 10 minute Bluetooth pairing window hasn't expired. If it has, you will need to completely remove and reapply the power (including USB).
Check that you're not attempting to use Bluetooth with an Apple device.
