RACBH1/2/3 are three different HDMI cables for use with the 3XD Pro. The 3 cables are full sized HDMI, Mini HDMI, and Micro HDMI. These HDMI cables are used to connect a camera to the 3XD Pro’s in-arm cabling port. This allows for live transmission to a monitor via the in-arm cabling. This allows for convenient monitoring and control over the cameras image and allows for easier composition and adjustments. The RACBH1/2/3 cables are compatible with 3XDPRO gimbal.
