The Snorkel mode is used to implement the pan and horizon functions of the Revolution
snorkel (or similar lenses) that require synchronizing horizon rotation to the pan rotation
with a ratio of 1:2. This mode is indicated by the letter S in the main screen to the left of
the radio channel indication. When the system is in this mode,
neither the iris nor the
zoom motor will calibrate
. This is because the Snorkel lens doesn’t have mechanical stops
on the pan and horizon axes.
The Custom mode 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,
the focus knob of a single hand unit can control the focus rings of three separate lenses
simultaneously. This mode is indicated by the icon C in the main screen.
The Custom mode is configured by pressing Set-Up. The Assignment screen appears in
the left figure below. 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. The middle figure below shows the Focus
function selected.
A hand unit function can also be turned off as shown in the figure above, right. This
choice is used when a single function hand unit (Focus/Iris or Radio Micro Force zoom) is
used to
exclusively
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 back and forth between the setting of the HU3 and the other hand unit.
In situations where the lens setting must be controlled only by the single function hand
unit, the corresponding HU3 channel should be set to “Off”.
The 3D mode is used in conjunction with user supplied 3D rigs which have motorized
control of both the camera convergence angle and inter-ocular camera separation. After
the user sets the convergence distance, the inter-ocular distance can be changed “on the
fly” and the convergence angle will automatically change to maintain the correct
convergence distance.
