Troubleshooting
Problem
Solution
No activity of the status LED
Verify the USB connection, also try a different
USB cable.
Device in reception mode, but not valid AIS
messages received (no ¼ second green flashes)
Verify the antenna connection and location.
Good AIS reception requires line-of-sight, verify
your setup from a location that is certain to have
traffic, e.g. near a harbor.
Device indicates valid AIS messages (¼ second
green flashes), but no messages received on PC
Verify that the serial port shows up on the PC. Try
a different USB cable if this is not the case.
Verify the serial configuration of your software.
Verify the serial communication with a serial
terminal program like Putty or screen.
Software receives positions, but fewer than
expected and/or with worse range than
expected.
Verify the antenna connection and location.
Good AIS reception requires line-of-sight, so the
higher up the antenna is positioned the better
the range. Move the antenna away from sources
of electrical noise.
After some time, dAISy indicates a device error
(fast blinking red LED)
Sometimes the device is not properly initialized
when the connected computer wakes up from
sleep mode. Unplug dAISy and plug in again to
resolve the error.
