There are pots on the back of the G-5500 control allowing for adjustment of the full scale reading and for output adjustments, for each of AZ & EL. Tweaking the output pots corrected the display on the LVB Tracker but didn't affect the meters on the G-5500, so I think that may be the solution.

This evening I connected my new to me LVB tracker to the G-5500 control box (also new to me) for the first time..all seems well except that the azimuth reading between the G-5500 control & the LVB tracker are 255° apart. I know the array is pointed west, the G-5500 box indicates west, but for a reason I'm not aware of presently the LVB Tracker shows +15°. Any thoughts?
