You mentioned something about only going one direction?
The Victors Require Calibration to mesh up with the calibration on your joysticks. The OI has a range of -126 to 126 (from what i remember) for the joysticks, -126 being fastest backward speed and 126 being Fastest Forward Speed and ZERO (the Mid point Number) would be your neutral (Using the dashboard program from IFI can help u calibrate in a snap)
anyways your joy stick could be off center yet your victor thinks it is centered so this off set with provoke the victor to run oppsite direction of the offset, if the offset is incredibly bad your ranges could be Fastest Foward Speed 126 and your neautral -126 (-126 becoming your new Zero)... that means that since there nothing under -126 then you simply cant go backward because that would be out of range. that could explain your one direction problem. Ive had times when Victors All sudden Need to be Recalibrate for seemingly no reason. it could be a short causing the victor to reset to its original position which may Completely be off with your controls (Calibrate Both together!!!!) For instructions on Recalibrating see the Victor Manual. it tends to be a two person operation. so get someone who will not move the controls while this occurs and move them when they Have to.

Osc,

Actually, the PWM output is:
0 = Full Reverse
1-126 = variable reverse (1 is fastest)
127 = no movement
128-253 = variable forward (253 is fastest)
254 = Full Forward
255 = Do not use

Secondly (and please understand that there are many ways to skin a cat), I've been electrical mentor on 177 since 1995 and, since the IFI controls came out, I have never had to calibrate a Victor. We check the trim on the joystick trimpots before every match and, if necessary, retrim to "zero" (PWM = 127 when your hands are off the joystick). After trimming, we use electrical tape to "clamp" the trim and keep the operators from accidentally hitting the trim wheel during a match.

Works like a charm...
