I didnt think the management soft ware needs to run, when open cpn
pro ais is used to configure the class b bits and show the ais is working on first installation
also a com port cant be shared without some extra software
1 turn on computer.
2 when fully booted
3 if the usb connection is a rs232
it in , let its drivers load then connect the ais to it
4 If usb connection is just a wire to the ais, turn on ais and connect usb.
then in settings check the correct com port is configured.
hope that has been a help.
