• Check MMSI number
and static data has been
correctly configured.
• Check GNSS antenna is
properly connected and has
a clear unobstructed view of
the sky.
• Check the VHF antenna is
properly connected and is
not short circuiting to the
vessel structure.
• Check that power supply is
at the correct voltage (12 V
dc or 24 V dc).
• Excessive difference
between Heading from
an input device and COG.
Blue
Transceiver is running in silent
mode (not transmitting), if you
want to disable silent mode:
• Check the AIS Silent mode
setting on your MFD.
• Check the position of the
dedicated Silent mode
switch, if fitted (The switch
will override the MFD
setting).
• Where no dedicated switch
is fitted, check that the Light
Green and Orange wires on
the Power/data cable are
not shorting together.
6.2 Troubleshooting
Problem
Action required
No power
• Check the power supply is properly
connected.
• Check the power supply voltage is
correct (12 V dc or 24 V dc)
• Check relevant fuses have not blown
or circuit breaker has not tripped.
AIS con-
figuration,
static data
is not be-
ing saved.
• Switch off all associated MFDs, then
retry configuration.
• Disconnect all connections then
connect only the USB cable to a PC

• Check SeaTalkng ® / NMEA 2000 or
NMEA 0183 connection and ensure
proper connection.
• When connected using NMEA 0183
ensure the port used to connect
your transceiver to your MFD is set
to 38,400 baud rate.
• Ensure the MFD is either; connected
directly to the same CAN bus
network as your AIS transceiver, or
the same SeaTalkhs ® network as the
MFD that is connected to the same
CAN bus as your transceiver.
