For manual calibration, tap the motor you wish to calibrate listed under “Manual” to enter
the manual calibrate screen (as shown to the left). Move the iris slider to the center
position as indicated on the screen – a center mark will appear and further instructions
will be shown on the screen. The slider will now be used to run the motor until the first
end point of the lens is reached. The farther you move the slider, the faster the motor will
go, so when you get close to the stopping point, slow the motor down by moving the
slider back toward the center position – the motor stops moving when the slider is at the
center position. If you move the motor too far, you can reverse it by moving the slider in
the opposite direction past the center position – this will move the lens back (stop the
motor by returning slider to center position). When the first end point is reached on the
lens, tap the “OK” button. Now move the slider in the opposite direction to find the other
end point for the lens. Stop the motor at the correct end point for the lens, and tap the
“OK” button again. The lens is now calibrated, and you will automatically be returned to
the home screen. Repeat this again per motor that needs calibration.
6. Setup Menu
The setup menu is where you can adjust power feedback, Com
Mode, and Backlash compensation for each individual motor.
“Power Feedback” will allow you to adjust the motor’s output power during auto
calibration. Some lenses require more force to move the lens rings than others. If the
motor’s power is set too low, then the motor will not have enough force to push the lens
gear to its limits, and result in incorrect calibration. If the motor’s power is set too high,
the motor will exert too much force, and potentially slip off the lens ring, also resulting in
incorrect calibration. The system defaults to 50.1 for each motor, and this is where it will
return if the “Reset All” button is pressed.
“Com Mode” will change how the hand unit will operate. Tap the button to change how
the hand unit will operate. “Wireless” will allow the hand unit and receiver to
communicate wirelessly. “Wired” will disable the wireless card on the hand unit, and
allow the hand unit and receiver to communicate through an optional communication
cable (that will also provide power to the hand unit, also allowing the hand unit to be
powered without a battery). “Upgrade will also disable the wireless card, as well as all
