So, the class B AIS (a transceiver, I'm presuming?), receives GPS at a lower baud rate from OpenPlotter, and provides AIS target charting to OpenPlotter at the higher baud rate? If so, I'd not considered that duplex at different speeds was do-able.(2019-07-02, 10:41 AM)Melipone Wrote: Thanks! I thought maybe as you only mentioned 2 wires I'd need something for 4, but I suppose the VHF doesn't need to send any data to the Pi. Will give it a try!
Before I bought a Class B AIS, I connected the NMEA out of radio at 38400 baud to my opencpn to have the AIS on screen. I had a separate adapter for each direction because of the baud rates.
Am I understanding correctly?
