WolfVision VZ-27 User Manual

QUICK INSTRUCTIONS VZ-27/VZ-57 ENGLISH

This page is only required for installation of the unit. The next page describes everything a typical user should know about the
Visualizer. More detailed information can be found in the detailed instruction manual (in English and German).

During transportation protect the unit from excessive shocks and cover the mirror with the supplied mirror protection !

Make sure that sufficient air circulation for cooling the unit is possible (v entilation slots on the left and right side of the unit)

To reduce the risk of electric shock, do not open the unit! No user serviceable parts inside! Refer servicing to qualified

service personal only! To reduce the risk of electric shock or fire, do not expose this unit to rain, moisture or extreme heat!

Precautions (Safety information)

Do not stare into the laser beam (VZ-57)!

Connections

#34 Main POWER switch
#35 FUSE
#36 POWER connection
#37 DVI output

DVI is a 100% digital output. It is the output with the
highest quality (resolution and color).
With a DVI connection the Visualizer can check the
technical data of the display unit connected to the
Visualizer (for the "Auto resolution" function)
Please note that the DVI-output does not output images
from the External Input (#42) of the Visualizer.

#38 USB port

The USB port can be used for quickly scanning still
pictures from the Visualizers into a PC. Connect the
USB port of the Visualizer to the USB port of your PC.
For installing the USB software you can use the
enclosed CD-ROM, but we recommend that you first
check on the Internet at

www.wolfvision.com/wolf/techinfo.html if a newer

version of the USB-software is available!

#39 SERIAL port (RS232)

For external remote controlling and Firmware updates

#40 PREVIEW RGBHV output (15-pin D-Sub connector)

for a control monitor
Please note that unlike all other outputs this output can
not be switched on and off with the Image key (#17). An
image is always output here for cont rolling purposes.

#41 RGBHV output (15-pin D-SUB connector)

Connect this output to your display unit (data projector,
monitor, video conferencing system ...)
When the display unit is connected to the Visualizer
using this output (or the DVI-output #37) the "Auto
resolution" function of the Visualizer checks which units
are connected to the Visualizer and automatically sets
the output to the mode that fits best for all connected
units (SVGA, XGA or SXGA). Please note that the
Visualizer can not check the best possible output mode,
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.
You can use the on-screen menu of the Visualizer to
change the output mode of the Visualizer between

Make sure that the mirror is always kept clean in order to prevent bright and hazy spots in the picture!

Clean it carefully with a soft tissue!

SVGA, XGA and SXGA and 60 or 75Hz.
If you can not see the menu you can also switch
between the different output modes by simultaneously
pressing the keys Image (#17) and Mirror (#12).
Make sure that you set the outputs to the native
resolution of your display unit and not the maximum
resolution it can display (in compressed mode)!

#42 EXTERNAL Input for Computers

Connect the monitor output of your computer with this
input. Use the Ext/Int key (#50) to switch between the
image of the Visualizer and the image of your computer
to be output by the RGBHV outputs (#40 and #43) of the
Visualizer.

#43 RGBHV output (BNC connectors)

Use this output to connect the Visualizer to your display
unit (data projector, monitor, video conferencing system
etc.) if you can not make a connection with a D-Sub
cable (RGBHV output #41).
The disadvantage of this output is that the "Auto
resolution" function does not work here. The advantage
is that BNC cable s are better for long cable runs.
You can change the sync settings in the on-screen
menu of the Visualizer.

#44 PAL/NTSC Y/C (S-Video) output

Please note that the picture quality of both PAL/NTSC
video outputs (#44 and #45) is NOT AS GOOD as the
picture qu ality of the data outputs (#37, #40, #41 and
#43). 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.
You can set the PAL/NTSC video outputs to PAL by
simultaneously pressing the keys IMAGE (#17) and
PRESET 1 (#14). You can set the outputs to NTSC by
simultaneously pressing the keys IMAGE (#17) and
PRESET 2 (#14).
Switching between PAL and NTSC can also be done in
the on-screen menu of the Visualizer.

#45 PAL/NTSC Composite video output

Only use this output if you have no other option. It offers
the lowest quality. Use the Y/C (S-video) output (#44)
for PAL/NTSC video if possible!

Control panel and infrared remote control:

#12 Upper MIRROR up and down (for scrolling)

The mirror can also be moved by hand! This does not
cause any harm to the unit

#13 ZOOM keys

When using the Zoom keys the size of the Synchronized
Lightfiled also changes. So the lightfield always
indicates the pickup area of the built -in camera. This
can be used for easy positioning of objects.

#14 User programmable PRESETS

You can use Presets to store certain positions of zoom,
focus, mirror, light etc.
Press one of the Preset keys quickly to recall a preset.
Press one of the Preset keys for 4 seconds to store a
Preset
In the on-screen menu it is also possible to assign a
specific function to a Preset (like Image on/off, IRIS,
Negative, Negative/Blue, Black/White etc.)

#15 IMAGE TURN key

For picking up a complete vertical (Portrait) page in A4
or US-letter/legal size in better quality, place your
document on the working surface in horizontal
(Landscape) direction and zoom in on it completely.
Then press the Image Turn key. Now the picture is
turned 90 degree and output the right way up with much
higher resol ution. This is because in the Image Turn
mode all pixels of the camera are used to pick up the
letter.

#16 TEXT Enhancement key

Press this key to improve the contrast and the
readability of text or x-rays. Please note that the colors
are slightly darker in this mode.

#17 IMAGE key

Switches the output image on and off.
Please note that the Preview- and Video outputs (#40,
#44, #45) can not switched off with the Image key
because they are intended for control monitors

#18 MACRO function

When pressing the Macro key, the length of the arm is
reduced automatically for bigger enlargements.
Please note that in the "Macro mode" the lightfield no
longer marks the pickup area of the built -in camera
On the VZ-57 a Laser Center Marker shows the middle
of the picture in the macro mode

#19 Manual FOCUS key

Because of the high depth of focus of the professional
Visualizers focusing is seldom necessary.
The focus is optimized for flat objects when the unit is
switched on or when both focus keys on the control
panel are pressed simultaneously.

#20 RESET key

Resets the unit to the default settings (same as when
the unit is switched on). If you also want to reset the on-

screen menu simultaneously press the Reset key and
the Menu (#23) key.

#21 LIGHT key

Switches between "Top light", "Bottom light" and "Light
off". The bottom light is recommended for x -rays and
slides. Transparencies may look better with the top light.
On the VZ-57 a Laser Center Marker shows the middle
of the picture when the bottom light is used
If you use the Visualizer to record objects outside of the
working surface, the light it is no longer identical with the
pickup-area of the built -in camera.

#22 Manual WHITE BALANCE adjustment

Each time the lighting condition changes (sun light,
neon light, halogen light...), the user should adjust the
white balance of the Visualizer, in order to optimize the
color reproduction.
For adjusting the white balance to the top light of the
Visualizer, zoom in on a white object until there is only
white on the screen. Then press the W.B. key. For
adjusting the White balance to the bottom light of the
Visualizer, switch the bottom light on, remove everything
from the working surface and press the W.B. key

#23 MENU key

Press this key for one second in order to see the on­screen menu on your screen. The on-screen menu can
be used for detailed settings of the Visualizer. It should
only be used by technically skilled persons.

#24 Manual IRIS

Using the Iris keys switches the Iris to manual. Using
the Zoom keys switches the iris to automatic again.
Special iris settings can also be made in the on-screen
menu.

#25 HELP key

in order to receive a help text (in English) about the
selected function.
