That's true for all other AIS transponders, but not the XB-8000. It's designed to be a primary GPS and outputs all the necessary GPS sentences.

Yes, you are correct. Switch the XB-8000 to 4800 baud output from the default of 38400. It outputs all GPS data at 4800 baud. However, it can't output AIS data at 4800.

It's always handy to be able to view the actual sentences if you are troubleshooting, but there is a list of the output sentences in the XB-8000
installation guide.

Actually, it will work fine. The only exception is if you need both AIS and GPS data and you are connecting a device that only operates at 4800 baud. In that case you can use a
NMEA 0183 multiplexer like the Brookhouse or Shipmodul that takes the 38400 baud output and splits it into two separate feeds at the different speeds by filtering out the high-speed sentences.

Yes, this is a good alternative to the multiplexer but does require installing another GPS.
