The Custom mode (Fig. 7.3) has two functions. The first allows the three MDR motor
channels, focus, iris, and zoom to be assigned to user-designated Hand Unit controls. For
example, in a multi-camera set-up, the focus knob of a single hand unit can be assigned
to focus, iris and zoom, allowing the focus knob to control the focus rings of up to three
separate lenses simultaneously. This mode is indicated by the icon C, (Fig. 7.5), displayed
on the main screen.
The second function of Custom Mode is to turn off one or more of the HU3 control
channels focus, iris, or zoom. This is useful when using the HU3 in combination with the
Focus/Iris or Radio Microforce single channel units. Turning off the HU3 channel will
prevent the motor from changing from the setting of the single channel hand unit to the
setting of the HU3 if the signal from the single channel unit is lost.
The Custom mode is configured by pressing Set-Up (fig. 7.3). On the Assignment screen
Fig. 7.6, the letters F, I, Z on the left column represent motor channels of the MDR and the
column on the right hand unit functions. The display indicates that the Iris channel of the
Hand Unit will control both the Focus and Iris motors, while the zoom motor is controlled
by the Micro Force zoom control.
To change the assignments of a hand unit control, use the Nav key to select and change a
Hand Unit control function in the right column. Figure 7.7 below shows the Focus function
selected.
The HU3 focus is turned off as shown in Fig. 7.8 above, right. This choice is used when a
single function hand unit (Focus/Iris or Radio Micro Force zoom) is used
exclusively to
split off a function from the HU3. In the “Normal” mode of operation, when the MDR
detects the presence of a single function hand unit, the MDR will respond to it rather than
to the HU3. When the single function unit is no longer detected, control will automatically
revert back the HU3. The corresponding lens position will therefore change between the
setting of the HU3 and, if present, the setting of the single function hand unit.
In situations where the lens setting must be controlled only by the single function hand
unit and not the HU3, the corresponding HU3 channel should be set to “Off”.
