"The Fl + Z system was the first wireless lens and camera control system to use a combination of digital and wireless technologies to achieve reliable operation. It quickly became an industry standard piece of equipment and was recognized by the Motion Picture Academy with a Scientific and Engineering award in 2007" (Howard Preston).
"The Fl + Z Lens Control System provides the highest resolution position and velocity control available. The Fl + Z Hand Control digitizes focus, iris, and zoom commands to 16 bits of resolution. This data is sent to the 3 Channel Motor Driver either through a cable or Microwave Link. The cable link uses the RS422 standard protocol to transmit data over a single twisted pair of wires. This enables reliable transmission over very long distances (1 km) even in the presence of electrical noise and radio frequency emissions. Position and velocity information are updated at 6 millisecond intervals to provide the feel of truly realtime response" (Mode d'emploi Fl + Z Lens Control, Santa Monica, Preston Cinema Systems, 1997).
