This is a long range single channel iris controller. No motor included. Posted on ebay here:
Basically it's a single channel system. It has a transmitter cradle, into which is mounted (and included) an iris paddle from preston cinema. That unit transmitts to the receiver which is pretty compact. The receiver will drive any digital motor (preston, heden, etc.)
Nice little system. I picked it up with a bunch of other items... and don't require it.
