The WFF Unit

A WFF unit consists of a hand-held Transmitter control, a
Receiver/Amplifier motor driver unit, and a power cable. To control
a lens, a lens drive motor and motor cable are required. To start
and stop a camera a remote control, or “run/stop” cable is required.

The Transmitter

The transmitter control unit, called just the ”Transmitter”, is a small,
lightweight, hand-held unit that enables the operator to remotely
control one lens function, such as focus or iris, and start or stop the
camera. The Transmitter has one main lens control knob (either a
rotary knob or a slider) three toggle switches for power and setup,
one rocker switch for camera on/off, one rotary selector switch for
channel selection, two LED’s, two connectors and one 9V battery.
