I am upgrading and want to pass this along to someone who can appreciate the robust and reliable nature of this generation lens control. 

The unit comes with a Run/Stop (trigger) cable for Sony PMW-F55 and a P-tap DC power cable.

This is some boilerplate for the item:

The MK 3.1 Motor Driver Receiver is the world's lightest and smallest, allowing it to be easily mounted to any industry standard camera. It supports up to 3 motors for FI+Z control (Focus, Iris and Zoom) and includes an auxiliary port for 2 analog inputs, trigger and digital serial communication. The system receives commands from any Teradek 4-Axis or 6-Axis Controller at up to 5000ft (1.5km) away and includes automatic or manual (softstop) calibration with a proprietary algorithm for torque control and lens protection.

I am not a professional seller. I sell things which were originally purchased for my own use and that I no longer need or use. 

Feedback is very important to me. I would appreciate if you could leave it for me once you have received your item. It lets me know you have received your item and are happy with your purchase.
