This is a PLC Electronics fStop Red Epic Run/Stop adapter. It works beautifully for the Bartech, and allows you to use any old Red One Run/Stop cable and spare a BFD Power Cable to deliver the 3.3v that the Red Epic needs to run. You can view more information on it here: http://www.plcelectr...Off-Cable-.html
I got it as part of a gear trade, and it turns out it doesn't do what I would want it to do, so I haven't even used it. It looks almost brand new.
$100 OBO plus shipping. (That's less than half price!)
