With AIS selected in the "Miniplex Config Tool" I tried using output 2, but there is no data flowing out of this set of terminals. Also tried Output 1 in the above post without success.
In AIS mode there is no data at all on "Output 1 or 2". AIS data is present in the "monitor" draw but shows in yellow only and no ships appear on the chart. This tells me the wiring between AIS receiver and RS-232 terminals on the 42-BT are correct. If they were not I should get nothing from the AIS receiver into the 42-BT.
I decided to do some basic testing with hardware.
I took the NMEA out from the Garmin GPS and connected it to the data bus where I have the VHF and SSB connected. All worked fine with GPS data showing on the radio displays.
Next, I hooked up the NASA, AIS receivers serial cable to a Keyspan converter and than direct to the USB port on the MacBook Pro. Immediately, three commercial ships showed on the MacEnc chart and all data in the monitor draw was green.
So, I know the VHF,SSB and AIS radios all work. With the Miniplex 42-BT in AIS mode there is no data on the outputs but there is data via Bluetooth, however, the AIS data is not acceptable to MacEnc as it shows in Yellow and does not display targets even when I know three ships are transmitting close by.
At this point I changed the mode using the Miniplex Config Tool to "Auto". In Auto I had NMEA data on Output 2 feeding both the VHF and SSB correctly and Bluetooth had data going to the computer. I did not check if any data was on Output 1. In Auto mode I connected AIS independently of the Miniplex using the Keyspan converter and this too worked properly.
The question is why no data on the outputs when in AIS mode? And, why is AIS NMEA data displayed in yellow and not showing on the chart when in AIS mode with ships transmitting?
