The yeoman is receiving GPS data via the NMEA mulitplexer ok, I haven't
yet tried changing the baud settings to get the yeoman to send waypoints
to the C120 plotter, but I will try and report back, at the moment I
connact my laptop to the newtwork via a 9 pin series connector, this
receives GPS & AIS data to make Winchart work, what I would like to
work out is how this data can get to winchart via the bluetooth
straight from the multiplexer, I am sure it's something to do with the
port configuration but I am not skilled enough to work this out.


As the Shipmodul 42 BT manual says (page 5, at the top) you need to
enable Bluetooth on your laptop and "pair" with the multiplexer.

- Enable the Bluetooth adapter in your laptop
- Go to My Bluetooth Places (usually a desktop icon)
- Otherwise, go to Control Panel Bluetooth configuration

From there you need to experiment a little since I don't have a BT
multiplexer.

Hope this helps,
