Found this cable while digging through my kit of Lemo cables this weekend. No idea why I built it, or for what, but someone out there must have a use for one of these! I already have too many Power/Video cables!
Could possibly run a consumer video transmitter, or use a consumer LCD as a backup monitor for your rig.
It's wired with a PRO standard 4 pin Power/Video Lemo connector, an RCA cable, and a consumer DC power jack (2.1mm ID, 5.5mm OD, standard for most LCDs and consumer stuff, also fits Decimators). Cable from end to end is about 22" long.
$55 shipped. The Lemo connector alone is worth half that.
