I was testing O 4.0 today by connecting to a class A kongsberg seatex AIS
by using the pilotplug(to USB) in addition to my exsisting GPS
( Digital yatch dualnav usb @115200 baud and proiority 0)
seems to display everything as excepted in opencpn
(normal AIS speed and priority 1).
For a test, I disconnected the usb plug
to the GPS
to check if the system was able to get position from the AIS. It seemed that the system as expected was able to continue to operate with correct position from the AIS, but I noted on the dachboard plugin that GPS satelites and statusbar was not displayed when using only the AIS as position refeence.
As soon as I plugged the usb gps back, it took only a few seconds before the gps status was back.
Tests proved that disconnecting and hot swapping the ais and gps usb plugs while opencpn
was running worked fine and that the system always continued to operate perfect on the secoundary position reference.
The system is running Xinutop Linux
It might be that the dachboard GPS status is by design not able to display when using an AIS pilotplug cable ??
