Connects the EXT socket (Fischer 16 pin) on the ALEXA, ALEXA XT and ALEXA SXT family of cameras to the EXT socket on another ALEXA, ALEXA XT and ALEXA SXT camera in order to synchronize sensor readout and HD output clocks for 3D and other applications where precise synchronization of two cameras is needed. Can be used concurrently with the Ethernet to Ethernet Cable (K2.72033.0), which allows synchronizing the settings of one camera to the other.
