This fixes two issues.

1.) You don't have to stop the camera to change servo posistions.
2.) You can't run victors off you camera anymore which was kind of a saftey
hazard as the camera doesn't know about being disabled. I'm pretty sure
this is why they were removed.

To make it work just run a PWM cable from the Analog or Digital port of the RC to the connector next to the switch. This will run your camera off the 12v supply instead of the backup battery. On the CMU board it has a "B" that is where the black wire goes. Then just run a serial cable from your computer into the CMUCAM.
Um, the servo PWM headers went away because the Ubicom SX52 microcontroller is no longer available and IFI was forced to transition to the SX48, which has fewer I/O pins. As it doesn't make sense to use the on-board PWM outputs for our application anyway, they were removed to aid in the transition to the SX48.

Using the camera PWM outputs to drive a victor would be strictly illegal under FRC rules, so I have no idea why this would be a problem that needed to be fixed.

The camera *must* be powered from a RC PWM header. Using power from any other header -- which supply 5 volts, not 12 -- won't work because the camera has its own voltage regulator and it needs an input voltage of at least 6.25 volts to function correctly.
