The OPTIONS (Fig. 8.6) selections consist of selecting distance units and knob direction.
Use the Navigation key to select the desired function. The default knob direction is CW.
Optional labels for the focus rings are available for CCW direction use.
9. The Zoom Bargraph indicates the position of the zoom when the zoom is in Normal
mode (See section 7. Operating Modes.) Note that the bargraph of the Digital Microforce is
not active when connected to the HU3, as the zoom position is only available when a
digital motor is used. The zoom bargraph indicates the lens limits as described in the next
section.
10. Lens Limits (Fig. 10.1) can be set using the three groups of set/reset (s/r) keys. To
set a limit, move the motor to the first limit and press the set (s) key. While keeping the s
key pressed, move the motor to the second limit and release the s key. The limits are now
set and indicated by a lit LED in the corresponding group.
To remove a limit, press the reset key r.
The Zoom bargraph indicates the off-limits areas of the zoom range by two lit strips of
LED’s. The span of the allowed travel corresponds to the length of the un-lit LED’s.
Lens limits can be used to
lock a motor to a given position. This is done by setting a zero-
span
, where the beginning and end of the range are the same point. To lock a motor,
position the motor to the desired point and press the set button twice.
11. Panatape and Cine Tape Interfaces.
The Panatape and Cinetape units can be used to provide a distance reading that is
displayed by the HU3 main display screen.
The Panatape interface p/n 4534 connects the data receptacle (5-pin Lemo) on the
Panatape to the 4-pin Serial receptacle on the MDR2.
The Cine Tape interface (p/n 4542) connects the Remote Lemo receptacle of the Cine
Tape to the 4-pin Serial receptacle of the MDR2.
The Panatape/ Cine Tape data is displayed as soon as the interface is connected to the
MDR2(Fig. 11.1).
