B4 Canon lens 12 signals
 

Hi
I am trying to mount a Everfocus Infrared Cmount camera with a Canon HJ22 lens on a Panasonic remotehead AW-PH400. Got the lens adapter c-mount to B4. Got the cable from the remotehead to the lens - but the IRIS will not be remotely controlled from the Panasonic remote. I supply the lens with 12v to the 12 pin connector but it seems as if there need to be somekind of a control signal on the 12 pin to enable the remote control of the iris on the lens. Help please :)
