The RIA-1 works with all existing CAM cables from the cforce mini RF motor, and all existing LBUS cables. We have also introduced a couple of new CAM cables that will also be compatible with the cforce mini RF motor, such as the new 8p Hirose cable for the Sony Venice 2. The serial port for connecting distance measuring devices such as the ARRI UDM-1 or Focusbug CineRT is the same as found on the ALEXA 35, but newer and smaller than the one found on the LCube CUB-1 and UMC-4.
