1. Description.
The V+F Lens Control is available as a single channel wireless/cable control (p/n 4050) or a cable
only version (p/n 4051). Both are used with DM-1 or DM-2 digital motors. The cable only version
is intended to control the iris function of cinema style lenses mounted on video cameras. In this
mode, the iris is controlled through:
the cameras’ remote set-up box (Sony RMB-150 or equivalent)
through the cable connected Remote iris Box (p/n 4020)
through the on-board control knob.
The wireless version adds the possibility of control through any of three wireless hand units:
Focus-Iris Hand Unit (p/n 4024)
FI+Z Hand Unit w/ MW Transmitter (p/n 4000 + 4910)
Radio Micro Force unit (p/n 4015 or 4016)
Wireless channels are indicated on the digital display. A three position switch adjusts the motor
torque level, and a second switch determines the direction of motor rotation.
The small size of the control makes it especially suitable for hand held use.
The FI+Z Hand Unit (p/n 4000 with Microwave Transmitter p/n 4910), the Focus-Iris Hand Unit
(p/n 4024) or the Radio Micro Force (p/n 4015 or 4016) can all be used for wireless operation
with version p/n 4050. The mode switch selects whether the unit responds to Focus, Iris, or
Zoom commands. Camera Run/VTR signals are available for controlling all film and video
cameras.
The unit operates over a voltage range of 11 - 30 VDC. For video cameras, all power and control
signals are provided through the 12-pin Hirose on the camera. Film cameras having accessory
receptacles capable of 1.5A @ 24V (Arri 435, Panavision) can also be used to provide both
power and camera run functions. Otherwise separate receptacles are provided for external
power and Camera Run/VTR.
