I have the run/stop cable that Preston sells and I use it with my MDR2 and HU3. It's worked fine on every job in the past, but today it wouldn't work for some reason. I've even used this exact camera body with it in the past and had no problems. My 1st wasn't sure what the issue was but thought that maybe a new build on the camera had changed something and caused it not to work. Anyone know what's up with this or have any recommendations for fixing this issue?

Here's Charles Papert's excerpt from "Open Red Thoughts and Discussion". Hope it helps.

"We had some head-scratching with the run cable at first; with the HU3 set for Arricam (I figured the momentary pulse for that camera would be comparable to RED), the first press of the run button trigged camera run as expected, but the next press to turn it off did nothing. We then hit the run button a third time and the camera shut off (but the HU3 of course was now showing it running). Eventually we discovered an incorrect setting in the camera which was causing this: you can designate either of the two 4 pin ports on the back of the camera to interpret the GPI triggers as camera run or ramp. They were correctly set for run, but you also have to designate what the action of the first and second trigger will be. GPI 1 is the first pulse that is received, which we set to "high" for camera run. GPI 2 is the second pulse, which needed to be set to "low" which turns off camera run (they were both on "high", which is why GPI 2 did nothing)."

Thanks Nick, and Charles. I'll try that if I have the same issue again. Although I'm using the accessory port on the side of the camera, not one of the 4 pin ports on the back. Not sure if there are a similar set of settings for the side port as there are for the back ports.
