Connects SMC-1, EMC-1 and AMC-1 motor controllers to ALEXA Mini EXT connector. Provides camera RUN/STOP function and tally. Length: 0.5m/1.6ftNote: ALEXA Mini may not supply the AMC-1 with enough power to drive three cforce motors at the same time. In this case, you may supply power from an additional power source through the unused cforce motor LBUS connector (e.g. K2.0006758 Cable LBUS to D-Tap 0.8m/2.5ft).
