I never knew the ZR3 was compatible with the 9500i until just recently(seeing as how the zr3 came out before the 9500i and old packaging doesn't mention it) So I wonder what would happen if you used the link cable from the 9500i and put it in the Sr7/Srx display port. (i know the display from the sr7/beltronics rx75 are interchangeable, I played with that once) Anyone have a sr7/rx75 and a 9500i wanna try to see what happens if it recognizes the sr7 controller as a zr3 shifter?
