Cable Operation; Wireless Operation - Preston FI + Z Manual

program should now report that it has found a connection to the MDR2 and asks whether you
want to proceed with the update. Choose yes. After the program has completed the update,
you can remove the serial cable from the MDR2.
A. Cable Operation
1. Couple the lens motors to the lens gears. Adjust the motors to have minimum backlash.
Do not couple the motor to the lens too tightly or binding will result. Check that the motor
brackets do not flex or slip on the matte box support rods. For normal lenses, the Torque
adjustment switches can be set in the middle position of their range.
2. Use the appropriate camera cable to connect the MDR2 to the camera accessory
receptacle. Please note that a special molded "Y" cable is required to control both the
speed and/or shutter angles of 24V Arri cameras (p/n #4510).
3. Connect The Hand Unit to the MDR using the Command Cable.
4. Apply power to the FI+Z system through one of the Power Cables (red strain relief). The
system requires 24V – 30 VDC (2A peak typical). If the Micro Wave receiver module is
fitted, its internal voltage converter enables operation from 11V to 30 VDC.
5. Press the Reset button to start the calibration sequence. The motors will find the
mechanical end stops of the lens and then come to rest. If the Hand Unit is linked to the
MDR either through a cable connection or through the Microwave Link unit, the motor
will immediately move to the positions corresponding to the current Iris and Focus
settings on the Hand Unit.
6. Check that the direction of motor rotation relative to the Hand Unit is correct by changing
the positions of the knobs in the Hand Unit and observing the lens. Use the Direction
Reversing switches on the Motor Driver Box as required.
7. Plug the Micro Force Zoom Control into the F I + Z Hand unit using the adapter cable
provided. Set the maximum zoom speed using the 10-turn adjustment potentiometer at
the bottom of the control.
8. It the zoom motor rotates without any pressure applied to the joystick, momentarily press
the "Zoom Cal" button on the FIZ control. This automatically removes any zoom offset,
which could cause "creep".
B. Wireless Operation
9. Determine whether there are any other FIZ wireless units operating in the vicinity. If
there are, determine what channel(s) are being used, and choose a different operating
channel.
10. Plug the Transmitter module into the Hand Unit. Be sure that the Velcro pads and the
Transmitter and Hand Unit are mated together.
11. Screw the transmitter Antenna onto the connector on the top of the unit.
