Arri SR / 35-3 4pin handgrip pinout

[Jules Forssell]

Hi everyone,

I’ve looked around but can’t seem to find any info on this.

Does anyone know the pinout to the 4pin trigger handgrip port found on Arri sr1/2 and Arri 35-3 ?

I’m looking to power an Arri zoom handle/motor that uses such a connector but from a different source.

Any help would be appreciated,

Jules

As seen from the side of the camera with the connector, as labeled on my french motor SR 
negative switch switch positive 


to make it run just connect both switch contacts. I sadly dont know the specifications of the dc output, though it should be +12v
