The WFF Unit RECEIVER BACK 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... - Page 5 Connector Pinout TRANSMITTER BOTTOM POWER IN (p. 4) DATA OUT (p. 4) 1: +7 TO 15 VDC 1: GROUND 2: GROUND 2: RF SHUTDOWN (SHORT TO GROUND) 3: DATA OUT RECEIVER FRONT PWR (p. 7) DATA IN (p. 7) 1: +11 TO 17 VDC 1: GROUND 2: GROUND 2: RF SHUTDOWN (SHORT...

When I switch the transmitter on the light on the receiver turns Transmitter Controls green but moving the knob on the transmitter doesn’t make Control Knob: Each Transmitter has one main control knob, the motor move. either a rotary knob or a linear slider. Once the lens The most likely cause of this is that both calibration knobs are in drive motor has been calibrated to the lens at the the start position (rolled all the way towards each other). - Page 7 Troubleshooting Other cameras, such as the Moviecam Compact, I cannot get the receiver/amplifier to receive the signal from require a momentary contact closure to start the the transmitter (receiver/amp LED stays red or flickers camera and another momentary closure to stop the between red and green).

Other Things to Know DATA OUT Connector: This 3-pin connector is provided to allow direct connection of the Transmitter and the Interference from Video Transmitters: UHF video Receiver/Amplifier unit. When connected, the transmitters, such as the Modulus 2000 or 3000, tend to broadcast RF sections in both the transmitter and on other frequencies than the intended frequency. - Page 10 The calibration knobs still set the ends of lens travel, but the calibration is slightly different. The calibration toggle switch has no effect and should be set in the middle position. Simply move the remote pot control all the way to one end of its travel. At this point, one of the calibration wheels will have a large effect on its operation, and one will have little effect.

Either one may be used for connection to an external 11 to 17VDC power source. If two WFF’s are being used and only one power source exists, Receiver/Amplifier Controls plug the second Receiver/Amplifier’s cable into the ON/OFF Switch: This switch controls power to the unused power connector on the first one. -
