If you are unable to connect your AIS transponder USB, then you should follow this section. The USB drivers are automatically downloaded with ProAIS2.
I am sure your USB drivers and proAIS2 software are fine, the key issue is the power up sequence. Please power cycle the transponder in the following manner, which works every time when you have it connected to a PC….
- Turn off the 12/24v supply to the transponder and unplug the USB cable
- Close the proAIS2 software and any other navigation software that uses COM Ports or USB Virtual COM ports
- Plug in the USB cable – the Red and Yellow LEDs should illuminate on the transponder
- Run the proAIS2 software, make sure the AIS Transponder is shown in the drop down menu and click the “Connect” Button.
- The PC should query the transponder and after a second or two, display the boat data (MMSI number, Name. etc.) in the data boxes
- Turn on the 12/24v supply to the transponder and it will start to try and get a position fix and then start transmitting
