[OZAPRS] GlobalSat BU-303

[Paul]

I'm trying to change a USB plug to a DB9 serial plug on a GlobalSat BU-303 USB GPS mouse so that I can use it with an Opentracker +, but for the life of me I can't work out the wiring for the data in and data out. The power to the gps mouse isn't a problem, goes to tracker pins 4 & 5, but the wiring for data to tracker pins 2 & 3, data in & data out, I can't get to work (with only 2 wires left to go to 2 pins you would think this would be a no brainer).

Has anyone had any experience with this type of gps mouse or know of any problems using it with the opentracker.

Any help greatly appreciated

Cheers
Paul
