Re: Vex UltraSonic rangefinder

I haven't done this on the FRC controller (so YMMV) but on a different controller I have used both. The wiring for vex was

both red wires to +5
both black wires to Gnd
Yellow is same as srf04 TPI
orange is same as srf04 EPO

Re: Vex UltraSonic rangefinder

haven't worked with those in awhile, but both red and black are +5V and GND.

now the yellow/orange are input and output. Not sure which, so you will have to look on the red plastic case you took off. One is a signal in, and one is a signal out.

This thread explains how the Vex sensor works. I am unaware if WPIlib supports this type of rangefinder.
