Troubleshooting | V3100 User Manual
Possible cause and remedy
• The Class B device requires GPS information
from GPS antenna before making AIS
transmission. Please check if your GPS antenna is
connected correctly. The Tx LED will flash orange
every 5 seconds meaning that the device is still
acquiring a GPS fix and therefore not ready yet to
make a transmission.
• For each transmission, the Tx LED indicator will
flash once quickly. The green light from the Tx
LED could be missed if not observed carefully.
• VHF antennas interference: if you are using a
dedicated AIS/VHF antenna for your transponder,
be sure that it is placed following the instructions
in section "VHF antenna installation" on page
14. In several tests, mounting two VHF
antennas next to another typically reduces the
transmitting range to both antennas by 50-70%.
• GPS is not fixed: If your GPS antenna is not
connected or setup correctly, your transponder
will see other vessels fine, but you will not be
sending out your vessel position, see section
"GPS antenna installation" on page 15.
The Tx LED will flash orange every 5 seconds
meaning that the transponder is still acquiring
a GPS fix and therefore not ready yet to make
transmission.
• The location of VHF antenna is directly related
to AIS transmitting range. The VHF antenna
should be installed at mast as high as possible.
• Please check that the power supply is
connected correctly at V3100.
• Please check that the power supply is 12V or
24V with sufficient current capacity (no less than
2A).
• Please make sure that the connections between
V3100 and the chartplotter are correct.
