Troubleshooting
If the guidance given in the table above does not rectify the problem you are experiencing, please contact your dealer for further
assistance.
Issue
Possible cause and remedy
No data is being received by the chart plotter
•
Check that the power supply is connected correctly.
•
Check that the power supply is a 12V or 24V supply.
•
Check that the connections to the chart plotter are correct.
No indicators are illuminated
•
Check that the power supply is connected correctly.
•
Check that the power supply is a 12V or 24V supply.
The Red 'error' indicator is illuminated
•
The unit may not have a valid MMSI. Check that the AIS transceiver is
correctly configured with a valid MMSI.
•
The VHF antenna may be faulty. Please check the connection to the VHF
antenna and that the VHF antenna is not damaged. The red indicator may
illuminate briefly if the power supply is interrupted or the VHF antenna
characteristics are briefly affected.
•
No GPS position fix can be obtained. Please check the transciever is located
where the internal GPS antenna has a clear sky view or that an external GPS
antenna is properly connected and installed. Review the GPS signal strength
graph available in proAIS2.
•
The power supply is outside the allowable range. Check that the power supply
is within the range 9.6V to 31.2V.
•
If none of the above correct the error condition please contact your dealer for
advice.
•
Check for error and alarm messages in proAIS

My MMSI is being received by other vessels
but my vessel name is not shown on their
chart plotter or PC
•
Some older AIS devices and chart plotters do not process the specific class B
AIS message which provides the vessel name (message 24). This is not a
fault of your AIS transceiver. Software upgrades are available for many older
chart plotters which will correct this issue. The other vessel should update its
AIS unit and/or chart plotting software to receive AIS message 24.
