Aux 232 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 GPI signals 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.
Note: Do not attempt to power a cinema lens motor from this connector. Depending on
your max current requirement, extract power from either one of the two Auxiliary Power
outputs, or the D-Tap connector on the battery V-Plate.
