Preston FIZ/MDR Connections

The Preston MDR Mark II or III can be connected with the Airtrack with the included Preston 3 pin or 4 pin cables. The connection on the Preston MDR motor controller is labeled Serial.

To get the best performance and lens sync from the Preston, the firmware on the MDR motor controller should be updated.

To update your Preston FI+Z unit you will need a Serial to Lemo cable (part # 4538) and a usb-to-serial adapter if the computer where the update is being performed does not have available Serial COM ports.  The latest downloads are avaiable from  Preston’s website.
