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.

If connected via NMEA0183, ensure that you have set the input port on the
chart plotter to 38400 baud
No indicators are


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 or flashing

The unit may not have a valid MMSI. Check that the AIS transponder is cor-
rectly 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 proAIS2
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
NMEA0183 Class B AIS message which provides the vessel name (message
24). This is not a fault of your AIS transponder. A software upgrade may be
available for older chart plotters which will correct this issue. The other
vessel should update its AIS unit or chart plotting software to receive AIS
message 24.

Some newer chart plotters do not accept the Class B static data PGN via
NMEA2000. Contact the manufacturer of your chart plotter to see if a soft-
ware upgrade to fix this problem is available.
