1. Pull the arm upwards using the special pull ring (#8)
2. Turn the camera head (#1) and point it at the working surface
3. Connect the power adaptor to the DC-input (#18).
4. Connect your output unit (projector, monitor, video conferencing
unit etc.) to the appropriate output of the Visualier (#12, #13, #14,
#15 or #16).
For choosing the right output please read the detailled
description on page 5!
5. Switch on the Visualizer with the power switch (#5)
Power-on preset:
The power-on preset is automatically activated when switching on the unit. The settings are:
Zoom size approx. 20 x 15 cm (A5), Autofocus on, Autoiris on.
Choosing the right output mode (SXGA/XGA/SVGA at 75 or 60Hz)
The RGBHV- and DVI-output (#13 and #12) can output signals in the following formats:
- SXGA (1280x1024 pixel) at 60Hz
- XGA (1024x768 pixel) at 75Hz (default setting when resetting the resolution)
- XGA (1024x768 pixel) at 60Hz (default setting if auto resolution does not work)
- SVGA (800x600 pixel) at 75Hz
- SVGA (800x600 pixel) at 60Hz
The default setting is that the "Auto resolution" function is activated. In this mode the
Visualizer constantly checks which units are connected to RGBHV- (#13) and DVI-output
(#12) and automatically sets the output to the mode that fits best for all connected units.
Please note that the Visualizer can not check the possible resolution, if the connected units
or the cables* are not "Plug and Play" compatible. If the Visualizer can not detect the
resolution of ALL units connected, the outputs are set to the default of XGA (1024x768) at
60 Hz. (*Cables with plug and play compatibility must have a 15-pin plug on both ends with all pins connected)
If you can not use the "Auto resolution" function, you can select the output mode manually
in the on-screen menu of the Visualizer (see page 9) or with the following key combinations:
For a lower mode simultaneously press both ZOOM keys on the camera head (#10)
together with the number 8 (arrow-down) key (#29) on the remote control. For a higher
mode press both ZOOM keys on the camera head (#10) together with the number 3 (arrowup) key (#29) on the remote control. In order to reset the output to the default setting (start
point) of XGA (1024x768) at 75Hz, press both ZOOM keys on the camera head (#10)
together with the number 5 key (middle of the number keys #31) on the remote control.
In order to achieve the best picture quality you must set the outputs of the Visualizer to
match the native resolution of your display unit (e.g. LCD or DLP projector or monitor).
Important: What matters is the native resolution of the projector or monitor, not the
maximum resolution that it can display (in compressed mode). The native resolution is the
actual number of pixels of the built in LCD display or DLP chip of a projector or monitor.
Most LCD or DLP projectors can also display higher resolutions than their native resolution,
but only in compressed mode and with inferior picture quality. Do NOT set the output of
the Visualizer to a higher standard than the native resolution of your display unit!
If you output the Visualizer image on a CRT-monitor or CRT-projector, use an output mode
with 75Hz, because 60Hz may show a slight image flickering. For LCD/DLP projectors or
monitors and video conferencing units 60Hz is the best choice. If you are unsure what is the
best mode read the user manual of the connected units.
PAL/NTSC video outputs
You can switch the Y/C (S-video) (#14) and Composite (#15) video outputs between the
video standards PAL and NTSC in the units on-screen menu (see page 9). Switching can
also be done by pressing both ZOOM keys on the camera head (#10) together with the Preset
1 (for PAL) or Preset 2 (for NTSC) (#21) key on the remote control.
Please note that the picture quality of both video outputs is NOT AS GOOD as the picture
quality of the data outputs (#12 and #13). This is because of the limitations of the PAL/
NTSC video system and because of the fact that this is just a converted Progressive Scan
signal and not an original video signal. The picture quality of the Y/C (S-video) (#14) output
is still MUCH BETTER than the quality of the Composite (#15) video output. Please note
that images from the EXTERNAL INPUT (#11) are not output at the Y/C (S-video) and
Composite output!
Manual focusing
When switching on the unit the
autofocus is automatically switched
on too. The correct focus is
continuously adjusted. The green
light beside the autofocus on/off
switch (#9) shines if the autofocus is
You can use the focus-keys on the remote control
for manual fokus. If the remote control is not
available you can use this method:
1. Place an object at the level you wish to
focus - The autofocus is focusing the object.
2. Switch off the autofocus with the on/off
switch (#9) - The focus remains unchanged
from now on.
Please note that objects with a very
low contrast (like a blank sheet of
paper) are difficult to focus. If the
autofocus does not work just move
the object slightly.
For special applications the autofocus
can also be switched off using the
on/off switch (#9). The autofocus is
also switched off when the manual
zoom keys of the remote control are
WolfVision lightboxes (optional)
Connect the power cord to the light box
connector (#19) on the back side of the
Visualizer. The light switch (#6) of the Visualizer
can now be used to switch between the light
of the Visualizer and the light of the lightbox.
Other lightboxes:
In order to prevent reflections the light of
the Visualizer always has to be switched
off when working with lightboxes.
Digital Zoom
Please note that the VZ-8plus has an optical 12x zoom, which is digitally increased to a 24x
zoom. The smallest pickup size on the working surface without (!) digital zoom is 23 x 31mm
(0.9" x 1.2"). When you zoom in further the digital zoom is automatically activated and the
smallest pickup size is 12 x 16mm (0.5" x 0.6"). However please be aware that when the
digital zoom is used the resolution of the picture is not as good as before. The default setting
is that a message appears on-screen when you are in the digital zoom mode.
You can change the behaviour of the Visualizer in the digital zoom mode in the on-screen menu (see page 9).
Shooting area on
the working surface:
Shooting area outside
of the working surface:
Turning the light backwards
In order to enable recordings with
illumination outside of the working
surface, the light of the Visualizer
can be horizontally turned an
angle of up to 250 degrees.
to infinity
Eliminating reflections
In order to eliminate reflections
(on high gloss photographs etc.)
just turn the light backwards
Please note that reflections can
also be caused by the room light.
Close-up adaptor lens
For shooting an object outside the working surface,
in a further distance to the unit, the close up lens (#7)
has to be removed.
In this case just pull the lens away from the main optic of
the camera until it reaches the locked position. It is
impossible to remove the lens completely from the unit,
therefore it can not get lost. Before turning back the
camera into the standard working position push the close
up lens back in.
White balance:
Correct white balance adjustment is important for true colors! The default white balance
setting when the VZ-8plus is shipped is "Auto Tracking". This means that the white balance
is continuously adjusted. If the colors appear to be wrong try to move any object in the
picture. However an "Auto Tracking" white balance can never be 100% correct.
For a more precise white balance adjustment use the "One Push" white balance. This can
be done by completely zooming in a white paper on the working surface and pressing the
LIGHT-key (#6) for 3 seconds. When the white balance is stored an on-screen message
appears. Setting a "One Push" white balance switches off the "Auto Tracking" mode and the
current white balance setting remains in the memory even when the unit is switched off.
When the lighting conditions change (e.g. different room light or sunlight) the white balance
should be readjusted!
For specialists: The VZ-8plus can be switched between "Auto Tracking", "One Push" and "Manual" white balance
mode in the on-screen menu (see page 9)
If you work with negative transparencies and an external light box, use a blank (dark) piece of the negative film for
white balance adjustment!
Slide Drawer
First make sure that you remove any object from the working surface
(very important!). Then insert a slide in the slide drawer. The camera
automatically recognizes the slide and focuses on the slide.
In case the slide is out of focus:
- Make sure that the slide is firmly in place
- Make sure that the ZOOM is not in the maximum tele
position (=smallest picture). Use the ZOOM-keys (#10 or #20)
Text Enhancement
For improving the readability of text, sketches or x-rays press the TEXT-key (#25). This mode
enhances the contrast of the picture. Please note that the colors are now darker than usual.
To switch off the Text Enhancement mode, press the TEXT-key again. While the Text
Enhancement mode is on, the message "TEXT MODE" is constantly displayed in the picture.
This should remind a user to switch off this mode when it is not needed anymore. The
constant display of the word "TEXT MODE" could be switched off in the on-screen menu of
the Visualizer (see page 9) however we do not recommend to do so. Because without this
message users may tend to open the IRIS, instead of pressing the TEXT-key, if the picture
appears to be too dark. This would cause a misadjusted picture.
Preset Function
The VZ-8plus offers the possibility to store the current settings as a Preset and recall them
by just pressing one of the three PRESET keys (#21) on the remote control. For storing a
Preset just adjust every function as required and then keep one of the PRESET keys
pressed for more than 2 seconds. The on-screen menu tells you when the preset is stored.
When the Presets are stored as mentioned above, all current settings like zoom, focus, iris
etc. are stored. Contrary to this, a user also has the opportunity to assign only specific
functions such as "Negative", "Negative/Blue", "Black/White" etc. to a PRESET key. This can
be done in the on-screen menu of the Visualizer (see page 9).
The USB output of the VZ-8plus can be used to transfer
Visualizer images onto a computer in just 2 seconds. No
additional computer hardware (like a grabber card) is required. In
this way the Visualizer can be used as a 3-D scanner for your
computer. Just connect the USB port (#16) of the Visualizer and
the USB port of your computer, using the supplied USB cable.
A dedicated WolfVision USB-software can be found on the CD-ROM. Please check our Internet
homepage at: www.wolfvision.com/wolf/techinfo.html if an update of this software is
available as a free-download. The software works under Windows 98/ME/2000. Windows XP
will also be supported. Windows 95 and NT will not work, because they do not support USB.
You can store 9 images and recall them by just pressing
one of the numerical keys (#29) on the infrared remote control:
Storing an image:
Press one of the memory keys (#29)
for more than 2 seconds
Recalling an image: Press one of the memory keys (#29)
By pressing the "All" key (#27) a split image with all 9 pictures
of the memory can be displayed.
If you would like to fill all 9 memories quickly (e.g. with your company logo or a black image)
just press the ALL key (#27) for 4 seconds. Then a new picture is stored every second until the
memory is full.
Split image of 9 picture memory
The VZ-8plus is equipped with a memory backup battery. It stores the pictures in the memory
when the power supply is disconnected for 1-4 weeks.
IMAGE TURN MODE (for higher resolution)
Working surface:
Normal mode:
Only 50% of the
pixels are used to
pick up the letter
Output picture:
Image turn mode:
90% of the pixels
are used to pick
up the letter
Picking up a complete vertical (portrait) letter
or A4 page has always been a critical issue for
a Visualizer, because the image is always
picked up in a horizontal (landscape) format.
So the camera could only use 50% of its pixels
to pick up a vertical (portrait) page. WolfVision's
new "Image turn" mode solves this problem.
Just place your letter (or other vertical object) on the working surface horizontally and zoom
in on it completely, so that about 90% of the pixels of the built-in camera are used to pick
up the letter. Then press the IMAGE TURN key (#22). The Visualizer turns the picture
electronically 90º and outputs it the right way up with much higher resolution than in
normal mode. The left and right margins are black.
A Computer can be connected to the External RGBHV input (#11) of the Visualizer.
With the Ext/Int switch (#26) a user can switch between the Visualizer and Computer
image to be displayed to the audience.
The signal from the computer is just looped through the Visualizer and is not processed
in any way. In order to avoid that your projector or monitor adjusts itself when switching,
it is recommended that you set the output of the computer to the same signal format
(SXGA, XGA or SVGA) and vertical frequency (75 or 60Hz) as the Visualizer. The default
output settings of the Visualizer is: XGA (1024x768) at 60Hz.
DVI-output: Please note that the image from the External RGBHV input (#11) can only be displayed on the analog
section of the DVI-output (#12) and not on the digital section of this output (see page10).
The following chapters are for experienced users only:
For standard use of the WolfVision Visualizer it is not necessary to go into the Visualizer's
menu and change settings. Inexperienced users should not make any adjustments there.
To enter the on-screen menu press the MENU-key (#28) for one second. Settings of the
Visualizer's basic functions and the built-in camera can be made here using the 4 select
keys (=the numerical keys with red arrows - #30). Please note that some basic settings in
the menu can only be changed you set the menu item "Format protect" to "OFF" first.
If you require more information on a function in the on-screen menu just set the cursor in the
respective line and press the HELP key (#31, This is a double function of the Number 5
key). Than a detailed description of this function appears on the screen. If you want to reset
the selected item to the default setting, just press the Number 5 key (#31) for 2 seconds!
The functions of the on-screen menu are not described in detail in this user manual as the
help menu is an integrated part of the Visualizer's software. The information you see on your
screen always belongs to the current Visualizer software (firmware).
All settings in the on-screen menu can be set back to the factory defaults. "Reset" is one
item in the on-screen menu. In case you can not read the menu on a screen you can also
set the unit back to the factory defaults by simultaneously pressing both ZOOM-keys on the
camera head (#10) and the Number 4 (back-arrow) key (#29) on the remote control.
If you only want to reset the item that is currently selected to the default setting, press the
Number 5 (#31) key for 2 seconds!
The output image of the Visualizers can be switched from positive to negative in the
on-screen menu. In addition the background of a negative image can be switched to
blue for better readability of text. You can also switch between color and black and white
in the on-screen menu.
TIP: If you switch often to negative, negative/blue or black/white images you can
assign this function to one of the Preset keys (see page 7) in the on-screen menu.
Auto Power off
In the "Power control" settings of the on-screen menu you can select that the Visualizer
will be automatically switched off, if it is not used for a certain time.
Changing the standard contrast (color) settings
If the picture or the colors on your screen appear to be too dark, you can lower the
overall contrast of the picture in the "Color settings" menu of the on-screen menu. The
settings can be made separately for the normal mode and the text-mode.
