This digital data can be sent either through a cable connection using the Command cable, or in wireless mode using the ML2 Microwave link. Power for the Hand unit is provided through the Command cable when a cable link is used or from the NMH battery pack when used in the wireless mode.
- Page 6 C. MDR-2 Fig.3 MDR-2 with Microwave Transceiver The 3 Channel Motor Driver (MDR2) uses a lens calibration sequence to automatically determine the mechanical limits of the zoom, focus, and iris rings of the lens. This sequence is initiated whenever the Reset button on the MDR is pressed, or whenever a motor is connected to the Motor Driver.

12. Slide a charged battery into the rear of the Transmitter. The Battery Release will prevent the battery from being accidentally released. 13. Set the Channel Switches on the Transmitter and Transceiver to the same channel. There are 30 channels available (00 – 29). Channels above 30 simply repeat the same channels (i.e. - Page 9 The Zoom Cal button provides automatic adjustment for electrical offsets in the zoom control (i.e. the control is out of adjustment). If any creep of the zoom is observed, momentarily press the Zoom Cal button while holding the Micro Force in its normal operating position without any force applied to the red joystick knob The Camera Run push-button switch allows control of cameras requiring either momentary pulses (Arri 24V cameras, Sony video cameras) or those requiring a constant control voltage...

A socket is provided at the bottom of the FIZ control for an external Iris control. When the external iris control is connected the slide control on the FIZ will be disabled. Fig5. Remote Iris Box p/n 4020 IV. MOTOR DRIVER FUNCTIONS The Motor Driver 2 (MDR2) is responsible for driving the motors, providing control signals to the camera, and transferring camera operating data to the wireless network through the transceiver module. -

are provided for : Panavision Zoom (48 DP 20 degree PA), Panavision Iris (64 DP 20 degree PA ), Panavision Focus (32 DP, 14.5 degree PA.), .60m, .70m . A lightweight bracket for Panavision cameras is available (p/n 4341). It is secured to the post adjacent to the lens mount, and allows up to two motors to be rigidly supported with short swing arms. -

3. Compliance Information This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: This device must not cause harmful interference and This device must accept any interference received including interference that may cause undesired operation. - Page 17 The calibration and run currents for the 3 channels are: IRIS: 650mA/900 mA FOCUS: 900 mA/ 1.2 A ZOOM: 800mA/1.2A To protect the motor from overheating due to a sustained stall condition, the processor will shut down motor drive if a motor is stalled for more than approximately 5 seconds. The system can be reset by either removing power momentarily or by unplugging and re- plugging the LEMO connector going to the motor.
- Page 18 If the unit is working normally with the red LED, the microprocessor may not be making good contact with its socket. The processor contacts require cleaning with an anti-oxidant (Pro-Gold). This procedure requires careful disassembly and should be left to our Service Department. 4.
