Setting up 1. Pull the arm upwards using the special pull ring (8)
3. Connect the power adaptor to the DC-input (14).
4. Connect a TV-monitor, a video projector or a video recorder to
the video output (12) or the Y/C-output (13)
5. Switch on the Visualizer with the power switch (5)
2. Turn the video camera head (1) and point it at the working surface
The picture quality is much better if you use the Y/C
(S-video) output (13) rather then the composite video output
(12). Especially with typed material in black and white.
When using the composite video output please make sure that
a dedicated video cable (75 with RCA plugs is used, and
not an audio cable with RCA plugs !!!

Please note:
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, Image on

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.
Eliminating reflections
In order to eliminate reflections
(on high gloss photographs etc.)
just turn the light backwards
slightly.
Please note that reflections can
also be caused by the room light.
to infinity
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.
Autofocus:
White balance:
When switching on the unit the
autofocus is automatically switched
on too. The correct focus is
continuously adjusted at a very high
speed. The green light beside the
autofocus on/off switch (9) shines if
the autofocus is 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
used.
o
(On the VZ-7D use the remote control for manual focusing)
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.
Connect the power cord to the light box
connector (15) 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.
WolfVision lightboxes (optional)
(for lightbox models: LB-7, LB-35 or Handy):
Other lightboxes:
In order to prevent reflections the light of
the Visualizer always has to be switched
off when working with lightboxes.
When the Visualizer is switched on it works with a precise automatic white balance. Please
note that immediately after the unit is switched on, the white balance adjustment may not be
100% correct. In this case just move any object in the picture. From this moment on it works
perfect. B
For some applications you may require a manual white balance setting. This can be done by
pressing the LIGHT-key (6) for 3 seconds. When the unit is switched off and on again it is set
back to automatic white balance. (Other white balance settings of VZ-7D see DIP-switch manual!)
asic prerequisite are white portions within the picture.

Infrared remote control (VZ7D only)
IMAGE on / off
One of the unique features of WolfVision's portable Visualizers is that there are
only 5 buttons on the unit. Therefore anyone can use it without any instructions.
For more experienced users there are some additional functions on the remote
control:
The Zoom keys are the most important keys on
the IR-remote control. That is why they stand out
in white color. ZOOM keys are also on the camera
head of the Visualizer.
When the Focus keys are pressed the Visualizer
switches off the autofocus function.
The next time the zoom keys are pressed the
autofocus is switched on again.
When the Iris keys are pressed the Visualizer
switches off the auto iris function.
The next time the zoom keys are pressed the
auto iris is switched on again.
Two zoom positions and camera settings can be recalled
by quickly (!) pressing the Preset 1 or Preset 2 key:
The factory presets are:
Preset 1: 80mm x 60mm, Preset 2: 290mm x 217mm
The Visualizer's image output by the video output (12) or Y/C-output (13) can be
switched on and off with these keys.
There is absolutely no monitor image distortion when switching on and off,
because the Visualizer actually outputs a black signal in the off position.
If the Visualizer can only be controlled from a
close distance or if it cannot be controlled at
all with the infrared remote control you may
have to change the battery.
Changing the batteries
Open the cover of the remote control with a
flat object (for example a coin or a big
screwdriver) and replace the two 1.5 V AA
batteries with new ones.

Furthermore a user has the opportunity to store his own presets. By pressing one
of the Preset keys for more than 3 seconds, the present camera and zoom settings
are stored as a preset. Please note that if the Visualizer is not used for a long time
the factory presets reappear when the unit is switched on again.

The serial port can be used to control the Visualizer through an
external device, like a remote control system for a whole
conferencing room.
It can also be used to control the Visualizer through a computer.
A special Windows-software for PC is available from WolfVision.
Please note that DecimaI-Codes (=ASCII-Codes or Hex-Codes) must be
sent as one single byte (e.g. 199 and not: 1 + 1 + 9) !
(detailed description of serial protocol available on request)
Switching to playback of a video recorder
WolfVision Visualizers do not have an input switch because the following method of
connecting a video recorder is much easier and requires no switching at all:
Connect the video output (12) or the Y/C (S-video) output (13) of the Visualizer to the
according input of the video recorder. Connect the video or Y/C (S-video) output of the
video recorder with the input of your monitor or video projector.
When the video recorder is switched to "Play", the picture of the video recorder
is shown (without any separate switching):

Adjust the video recorder so that the picture of the Visualizer will be shown
(Make sure that the input switch of the video recorder is in the right position.
If the video recorder has a TV-tuner switch to channel "0" or "AV"):
When the video recorder is switched to "Stop" again, the picture of the visualizer
reappears (without separate switching).
Please note that the VZ-7D and VZ-5D have an optical 12 x zoom, which is digitally
increased to a 24 x zoom.
The smallest pickup size on the working surface without (!) digital zoom is 23x31mm
(0.9"x1.2"). When you zoom in further the digital zoom is automatically activated and
the smallest pickup size is 12x16mm (0.5"x0.6"). However please be aware that when
the digital zoom is used the resolution of the picture is not as good as before.
