3.0 CAPABILITY, DEVICE FEATURES AND PRODUCT FEATURES
3.1 Device Capabilities
The VSM2000 scaler uses a proprietary scaling engine to perform its functions. This technology is
a powerful toolset for any application requiring high quality video signal conversion or image
manipulation.
The product features a single video processing and scaling engine. These functions allow the
flexibility for handling a wide range of inputs and outputs, depending on the unit used.
The product is at home in broadcast & display environments. The VSM2000 scaler offers a range
of high-level image processing functions.
This unit allows for a standard television video signal, such as Composite Video, to be input into
the unit and then converted for use on a computer display. When using this function you can
switch back to the computer image by pressing a button. This is known as bypass mode.
3.2 Device Features
General Topography
4:4:4 RGB / YUV sampling provides full bandwidth color which allows precise keying where
included in the unit’s capabilities. This can be achieved through the transparent (soft) keys on the
front of the unit. Each unit’s video inputs accommodate multiple video and computer signal formats
and resolutions – see specifications at end of manual for full details.
Ultimate flexibility
The VSM2000’s output signal format flexibility assures that the native resolution of virtually any
display can be matched. Because of the resolution calculator (included in the Windows® Control
Panel), even new resolutions can be added to the unit. Signal parameter adjustments can be
made for each video input and are stored in individual non-volatile memories for retrieval once the
unit’s power has been removed. The product employs pixel adaptive motion compensation to de-
interlace fast moving images, and automatic 3:2 Pull-down efficiently de-interlaces video from 24
fps NTSC film.
Simple Control
The unit can be controlled in various ways. One option is to control it from the front panel using the
transparent (soft) keys on the front of the unit. Another option would be to control the unit from an
infra-red remote control. It can also be controlled via RS-232 or via Ethernet using the Windows
Control Panel.
The Windows Control Panel is available for download from our Internet site and affords complete
control of the unit and adds Scripting to facilitate long, complex sequence of commands.
Upgradeability
The VSM2000 scaler benefits from firmware upgradeability, thus reducing product obsolescence
by allowing the installation of the latest version of firmware. This not only applies to the software
used to control the unit, but also to the range of resolutions stored inside the unit, the addition of
new features, and upgrades to the heart of the image processing hardware – the scaling engine.
See http://www.avocent.com/support for more detail.

5.0 FRONT PANEL CONTROLS
The range of buttons on the front of the unit provides the user with quick access for selecting a
variety of inputs and features.
The multi-directional switch on the front panel provides the user with a way of navigating the Liquid
Crystal Display menus (LCD) which is detailed in a later section. The RS232 interface and
optional infra-red remote control also provide further ways of controlling the unit, which are
detailed in a later section.
Button controls
A sub-set of the following buttons will be available on the front of the unit, depending on the model
in use:
Button Button Function
Multi-
directional

Press and hold in to store current settings into memory. They
will then be restored on power-on, or when a Restore is done.
See next section for more information.
RGB Selects an RGB input as the current source for conversion.
CV(n) Selects a CV input as the current source for conversion.
(n) Denotes a number. Some units may have more than one CV input
YC(n) Selects a YC input as the current source for conversion.
(n) Denotes a number. Some units may have more than one YC input
YUV Selects a RGB input as the current source for conversion on the
first press and then YUV on the second.
DVI Selects a DVI input as the current source for conversion.
FREEZE Freezes the current image (does not affect any background
image)
ZOOM Jumps to the ‘Zoom’ menu item.
(Further presses step Zoom between 100%, 150%, 200% and
300%)
PAN Jumps to the Zoom pan menu item and allows immediate
panning of a zoomed image using multi-directional switch.
5.1 Multi-directional switch
The LCD is controlled from the front panel by using the multi-directional switch (m/d switch). This
switch can be moved left, right, up or down and also pressed in. These functions let the user
navigate through the menu structure or change a parameter, and are detailed in a later section.

16
5.2 Special button combinations and functions
In addition to the ability to perform a factory reset and forcing certain output resolutions, other
button combinations are available:
These button combinations only work when the unit is switched on and active
i.e. with the STANDBY/ON LED is off. They will not work in Standby mode, or
during power-up.
5.2.1 Locking front panel buttons & IR remote control
This can be performed by pressing STANDBY/ON and FREEZE at the same time. All front panel
buttons and IR remote control commands will be disabled, with the exception of repeating the
above combination to un-lock the unit and for storing the current locked buttons setting (thus
letting you make sure the unit always starts up with the buttons locked). The IR remote’s LOCK
and STORE buttons will always be active, giving another way to turn button/IR remote locking off.
The STANDBY/ON button will flash when the unit’s buttons are locked.
5.2.2 Restore power-on settings
This can be done (without having to turn off the unit) by pressing STANDBY/ON and the multi-
directional switch at the same time until a single beep is heard.
5.2.3 Factory Reset
If you wish to restore all operational parameters to their original condition (for example, if saved
settings prevent the unit from working with your display monitor), hold the STANDBY/ON and the
multi-directional switch in together until two beeps are heard.
All stored settings except resolutions are lost when the unit is reset. A Firmware
update is the only way to perform a complete factory reset (including resolution
data).
5.2.4 Forcing default output resolution
Press and hold the RGB button and button 3 together, then release. The default output resolution
depends on the type of unit you have – see above.
