CHOOSING THE RIGHT VIDEO OUTPUT

(of VZ-15b or VZ-35b)

Y/C output (S-VHS - #37)

For live image projection it is reccomended to use the Y/C output as the signal passes a sharpness
enhancer. It even looks better than with the RGBS output of the VZ-35b. Only the Component output (YUV)
of the VZ-35b offers a better quality than the Y/C-output.

IMPORTANT

RGBS output (#40)

VZ-35b:

VZ-15b: On the VZ-15b the RGBS-signal is actually only a converted Y/C-signal. (As the VZ-15b has a 1-chip

Most RGB-monitors or projectors use a separate Sync connection. For units without a separate Sync connection
the Sync Signal can be added to the Green-signal.

The "Sync on green" function can be switched on and off by simultaneously pressing the following keys:
IMAGE ON (#22), FOCUS + (#17) and FOCUS - (#18). The factory setting is "Sync on green - off".

If "Sync on green" is switched on, make sure that no separate sync cable is connected - the result
could be a picture with too much green!

Component output (#40 - VZ-35b only)

The RGBS output of the VZ-35b can be switched to Component output (YUV) by simultanously pressing
the following keys: SAVE (#12), IRIS dark (#19) and IRIS bright (#20).

The connections are the following: Red=R-Y, Green=Y, Blue=B-Y

Composite video output (#32)

Only use this output if the other unit does not have Y/C or RGBS input. As this is the oldest standard, the
quality is not as good as with the other outputs.

The VZ-35b offers a true RGBS-signal. Red, Green and Blue are directly connected to each of
the 3 chips of the camera. As a result this output offers the best color reproduction. This signal is
also reccommended for image processing as it is the original (unprocessed) signal.

(On the VZ-35b this output can be switched to YUV - see below)

camera and no 1-chip camera has a true RGBS output). This output is intended for units which do
not have Y/C-input. The quality is better than composite video but not better than Y/C !

Preview video output (#31)

This is a composite video output for a control monitor. It's the only output that is not switched off, when
using the IMAGE OFF key (#21). Do not use this output for the audience's monitor or projectior!

RGBS OUTPUTS (VZ-45b)

The VZ-45b outputs an RGBS-signal with 50 Hz and 31.25 kHz.
This is a DATA-RGBS signal which can be used by most data-projectors or computer-monitors
.
However, you can NOT connect the VZ-45b to a video monitor or a video-projector which can not project
computer data (with a resolution of at least 782 x 582 pixels or 31.25 kHz)

IMPORTANT

Synchronization of a projector or monitor:

Most projectors or computer monitors adjust themselves automatically when the VZ-45b is connected.
However some may do a wrong automatic adjustment as the signal output by the VZ-45b is not 100%

S-VGA compatible. The S-VGA standard ist 800x600 pixels at 60 Hz and the signal output by the VZ-45b
is 782x582 pixels at 50Hz.You may have to go into the setup menu of your data-projector or computer­monitor to adjust these settings manually.

The factory-settings of the sync-outputs is HD/VD (i.e. separate horizontal and vertical sync-impulses) and sync­on-green off. This format is the same as the one used in the computer-industry so there should be no problems
with the most multiscan-monitors or projectors.

However, if your display-device does not support separate sync-inputs but has only one sync-input (normally
marked with S) you should switch the Visualizer to CSYNC (i.e. the combined vertical- and horizontal-sync­impulses are output on the S/HD-connector). You can switch between CSYNC and VD/HD by pressing SAVE
(#12) + IRIS dark (#19) + IRIS bright (#20) simultaneously.

If you want to use sync-on-green you can change between sync-on-green on and off by pressing SAVE (#12) +
FOCUS near (#17) + FOCUS far (#18) simultaneously. You can also change this setting in the camera-menu.
When sync-on-green is on you need only to connect R, G and B. Monitors which do not support this mode
often display a green picture.

Please note that the sync-outputs are the same on all three outputs (5 x BNC, Preview and RGB). So if you use
multiple display-devices you should use a mode which is supported by all display-devices. Many modern monitors
or projectors automatically detect the sync-mode so they should be able to work with most of the above Visualizer­settings. On some display-devices you can also change manually between these modes.

SWITCHABLE OUTPUTS (all Visualizers)

All outputs of the WolfVision Visualizers - except the Preview output (#31 or #43) - are switchable. Use the
IMAGE keys (#21,#22) on the control panel or the remote control to switch the signal supplied from these
outputs on and off.

Independently an image is always output by the Preview video output (#31 or #43).This output can be used
for a control monitor. A constant sync signal is supplied to all switchable outputs (even in the image off mode)
eliminating monitor image distortions when switching.

HOW THE VISUALIZER WORKS (all Visualizers)

b

a

A light projector (b) inside the WolfVision Visualizer projects the light via a mirror inside the unit and a mirror on the
reflector head onto the working surface. The video camera (a) inside the unit scans the picture where the light falls.

The optics of the camera and the light projector are synchronized. This means that when the size of recording area
is increased or decreased with the ZOOM-keys (#15,#16), the size of the illuminated area on the working surface is
also increased or decreased.

Thus the illuminated area on the working surface always indicates where the camera scans the picture. (In fact, the
scanned area is fractionally smaller than the light field.)

BASIC PREPARATIONS (all Visualizers)

1. Press the release
button

1. Press the release for the arm (#11) and simultaneously pull the arm upward. Make sure that the arm is extended
to its full length.

2. Connect the power cable to the unit (#36) and plug it in.

3. Connect a control monitor (if required) to the Preview video output (#31 or #43).

4. Connect a large viewing monitor or a projector to one of the outputs of the Visualizer.
For choosing the right output please read page the previous pages!

5. Turn the main power switch (#34, on the back of the unit) to "I". The red power indicator (#29) on the control panel
indicates that power is supplied.

2. Pull arm
upwards

6. Press the POWER on key (#28) on the control panel. The Visualizer now runs the "power-on preset" (=automatic
focusing of an A5 format on the working surface) during which the green LED light (#30) is flashing. As soon as the
green LED light stays illuminated you can start working with the Visualizer.

WORKING ON THE WORKING SURFACE (all Visualizers)

1. Place your subject material on the working surface. For background use either the white side or the black
side of the working plate. For some objects the best presentation can be made with colored background.

2. Tilt the reflector head (#10) so that the object is illuminated.
DO NOT TOUCH THE MIRROR,

AS FINGERPRINTS CAUSE
BRIGHT AND HAZY SPOTS
ON THE PICTURE ! ALWAYS
KEEP THE MIRROR CLEAN !

Monitor

TV-Monitor

3. Select the enlargement required with the ZOOM keys (#15,#16) on the control panel or the infrared remote control.

4. Adjust the sharpness with the FOCUS keys (#17,#18) on the control panel or the infrared remote control.

Video projector

CAUTION: SENSITIVE FRONT
COATED MIRROR!

FOCUSING ON FLAT OBJECTS (all Visualizers)

When the Visualizer is turned on the focus automatically adjusts to the working surface level. As a result
it is not necessary to readjust the focus if you are only working with flat materia (text, photos etc.).

Furthermore, due to the great depth of focus of the Visualizer it is rarely necessary to readjust the focus.
Only very high objects require a focus adjustment.

In order to reset the focus to the working surface level (for working with flat objects) just press POWER ON
(#28). This activates the power-on preset and resets the focus to the working surface level.

WORKING OUTSIDE THE WORKING SURFACE (all Visualizers)

For showing 3-dimensional objects with the WolfVision Visualizer, just place them on the working surface
and adjust ZOOM and FOCUS (as mentioned). Due to a special WolfVision lens the object can be up to 9.7"
(25 cm) in height. If the object is to big for the working surface or if you want to show it from the side just
place it behind or in front of the unit and tilt the reflector head.

In this way it is also possible to make recordings
of subjects in the room or surrounding area, as
with a video camera by just tilting the reflector
head.

Due to the great focal range it is possible to
show details even from a great distance to
the unit.

If you want to record people you should turn off the light with the LIGHT off key (#23), so that they are not dazzled.

LIGHTING (all Visualizers)

The lighting system is fixed for working on the working surface. Because of the oblique mounting of the
camera and the light projector of the Visualizer the light-field shifts to the left when the distance between the
Visualizer and the scanned object is increased. This means that the light field no longer exactly shows the
recorded area. The edges of the light field may also be unsharp. In this case switch off the Visualizers light
with the LIGHT off key (#23) and work with room light.

Lamp lifetime enhancement circuit:
Special lamp electronics prolong the lifetime of the Visualizer's lamp over 40%. This electronic function dimes
the light when switching on and off
