AUX / RS232 PORT
The Auxiliary / RS232 port provides up to 500mA of regulated +12V power to motorized 2/3” B4 mount
lenses. The two inputs labeled SW1 and SW2 are fixed function inputs that activate Record Start / Stop
and Playback of the last recorded clip respectively. These are typically triggered by the B4 lens, or by a
controller such as Preston MDR-2 using an appropriate adaptor cable.
WARNING: Do not attempt to power a cinema lens motor from this connector. Depending on your
maximum current requirement, extract power from one of the two Auxiliary Power outputs, or the
D-Tap connector on the battery V-Plate.
