the Digital Yacht Software and Drivers CD supplied with the AIT2500.
6. Troubleshooting
If the green LED is not illuminated after around 5 minutes then please check the following:
1. Is the MMSI number programmed?
Check the
“Diagnostics” tab in proAIS2. If there is a red cross next to the "AIS Transponder MMSI Valid" item then
you have not correctly configured the MMSI.
2. Does the unit have a GPS position fix?
Check the “Diagnostics” tab in proAIS2. If there is a red cross next to the "GPS position fix" item then the unit does
not have GPS fix. Check your GPS antenna and connections.
3. Is the unit reporting any alarms?
Check the "Active alarms" area in the “Diagnostics” tab of ProAIS2 & refer to the troubleshooting guide at the back of
the ProAIS2 user guide
.
4. Is there an external power connection?
When connected to a computer via USB, the AIT2500 can take enough power from the USB port to work as an AIS
receiver but not as a Class B+ transponder. Occasionally if a fault occurs i
n the boat’s wiring, a fuse blows or the
circuit breaker trips, then the AIT2500 will lose external power and only have the USB power. In these circumstances,
the AIT2500 will receive AIS targets but not transmit its own position and the Red and Yellow LEDs will be lit.
