The RED DSMC3 RMI Cable 1m provide spower and video to your RED Touch 7 inch monitor from your camera. Its 1 metre length allows you more mounting opportunities than using the 10 inch cable that comes with the RED Touch LCD. This proprietary RMI (RED Monitor Interface) cable is only for RED DSMC3 products. Please note that although the cable bears a resemblance to a standard USB Type-C cable, it is not, and RED recommends against using a USB Type-C cable in its place as damage can occur to your camera and/or touchscreen.
