[Xastir] WX station interfacing

[Matt Werner]

I have a 2000 and have no problems with it interfacing with xastir.  I
ran my cable from the junction box, not the display unit itself, but
don't recall any issues with the wiring.

I also have no problems with xastir displaying the negative temps correctly.
