Teradek RT CTRL.1 and CTRL.3 5-Pin USB Cable

CTRL.1 and CTRL.3 send focal distance, iris and zoom to a SmallHD monitor as an overlay, and that data travels down a 5-pin USB lead rather than over the air. Which one you need depends on the monitor's port and on how much room there is beside it.

The right-angle versions are the ones to fit when the monitor sits close to a cage or a mounting arm and a straight barrel would be under strain. Each is a separate Teradek part number.
