4. Setup Menu
The setup menu is where you can adjust power feedback,
Com Mode, Backlash compensation, and Controller input.
“Power Feedback” will allow you to adjust the motor output power during auto
calibration. Some lenses require more force to move the lens rings than others. If the
motor 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 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, 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
communication between the hand unit and receiver. This mode is only used when
making firmware upgrades, and requires a LEMO to serial cable.
“Motor Backlash” is used to compensate for backlash in the lens rings. Not all lenses
have backlash, and this is only necessary if the lens “lurches” when changing direction.
Backlash should be kept to a minimum unless necessary .
“Input Controller” simply allows you to switch between focus knob operation or iris
slider operation. Tap the button for the input controller that you wish to use. Most
operators will use the focus knob, but iris slider is available if you choose to use it.
