That is the only Device Link I know of and it is from the best of my remembering for the plane's X,Y coordinates

I'm confused. The readme of the mod says

This mod gives you access to all of your instrument readouts on-line the same as you have off-line.

The non modified version of the device link does not allow to query coordinates of the plane. I also don't see any reference to x,y coordinates in the link you posted ... :?:
