Yes, you can use combined output at 38400 if you ensure that the baud rate for Data3 is set to 38400.Yes, the Data3 Port monitor is where I see the AIS
Yes, AIS is selected as Input Sensor Type.
Can I use the combined output of AIS and GPS data at 38400 on the input signal to provide position along with AIS data?
When I use the rotokey to select Targets, I press it and AIS comes up along with History.
When I press it again the light on the AIS turns green, but nothing changes on the plotter display.
Also, when I bring Targets up again with the rotokey, the green light is not lit.
When you select AIS in targets and see the targets with history, just let it time out and AIS will remain selected with green light. If you press rotokey again, you're actually turning it back off.
