WolfVision VZ-17 - Handbuch (Seite 14)

EXTERNAL SYNCHRONIZATION
If Visualizer images are mixed and processed (fade-in, fade-out, mix/wipe) with images from one or more video
cameras (or Visualizers) using a special effect unit without TBC (time base corrector), all units connected must be
genlocked.

SOFTWARE UPGRADE
The software of your Visualizer (including the on-screen help menu) can easily be upgraded to the latest version. It can
be done by connecting a computer or a modem to the RS232 port of your Visualizer.
Please consult your WolfVision dealer or check our website (http://www.wolfvision.com/wolf/techinfo.html).
Please note that this reset-function does not reset the sync settings of the RGBS outputs or the RGBS / YUV
setting of the VZ-37! (To reset those settings use the key combinations listed on the back of this manual)
The on-screen menu also offers the possibility to store three different menu settings as Menu-presets.

A detailed description of the serial protocol (including status
report and position setting) is available on request from your
WolfVision dealer or can be downloaded from our website:

Genlocking is achieved by supplying the same composite video signal (VBS) or black burst (BB) signal to the
Extern Sync input (=Genlock input) of each unit connected.
In order to genlock the WolfVision Visualizer with another video signal, simply connect this signal to the Sync input
(#33) of the Visualizer where a composite video or a black burst signal can be connected.
With a VZ-37 fine adjustment of color-phase (SC) and H-phase can be made in the unit's on-screen menu.
With a VZ-17 it is necessary to open the unit and adjust the settings with a screwdriver on the camera itself. Please
leave this to a technically experienced person, as there is sensitive and potentially dangerous electronics inside the
unit!
Start with H-phase adjustment, followed by rough adjustment of "0/180" followed by fine adjustment with SC.
Genlock operation with a playback signal of a video recorder is only possible if the signal is time base corrected via
a TBC device.
POSITIVE/NEGATIVE SWITCHING (VZ-37)
The output image of the Visualizers can be switched from positive to negative in the on-screen menu.
TIP: If you require negative images often, you can store a Preset with these settings (see page 9). This saves you
from entering the on-screen menu for switching.
