2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in

associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VS-44HDCP away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

VS-44HDCP - Overview
3 Overview
The VS-44HDCP is a high quality 4x4 DVI matrix switcher. It reclocks and
equalizes the signals and can route any input to any or all outputs simultaneously.
It accepts up to four DVI/HDMI (over DVI-D connector) inputs and routes the
selected DVI input signal to any or all of four DVI/HDMI outputs.
DVI-D (Digital). Note that only the digital signal (DVI D) is available on the DVI connector.
In particular, the VS-44HDCP features:
Up to 6.75Gbps data rate (2.25Gbps per graphics channel)
Suitable for resolutions up to UXGA and 1080p at 60Hz
Support for HDCP (High Definition Digital Content Protection)
HDMI Support - HDMI support for Deep Color, x.v.Color™, Dolby® TrueHD,
Dolby Digital Plus, DTS−HD®, and linear PCM 7.1 surround sound
3D pass-through
Support for up to 7.1 multi-channel audio
Kramer reKlocking™ and Equalization Technology that rebuilds the digital
signal to travel longer distances
A LOCK button to prevent unwanted tampering with the buttons on the front
panel
Eight reset memory locations for quick access to common configurations
Support for Kramer Protocol 2000 and Protocol 3000
You can control the VS-44HDCP using the front panel buttons or remotely via:
RS-232 serial commands transmitted by a touch screen system, PC or other
serial controller
The Ethernet port
The Kramer infrared remote control transmitter
The infrared remote extension cable transmitter (optional), see Section 7.3

3.1 About Fast Switching
Older display devices required a longer time between the loss of one digital signal
and the introduction of another, as well as a physical disconnection of the
interconnecting cable in order to be able to detect and adjust to the new video
attributes and parameters. Normal switching, therefore, introduced a 5V signal
disconnection along with a delay in switching. Many newer display devices,
however, are now capable of “on-the-fly” switching.
Depending on the display device in use, the VS-44HDCP allows for fast switching
(minor reset and the connection kept alive) and extra fast switching (no reset and
the connection kept alive). Using the fast and extra fast switching modes allows for
fraction-of-a-second switching times when using high performance display devices
or when using a scaler on the video output.

6.3 Storing and Recalling a Setup
You can use the STO and RCL buttons to store up to eight setups and then recall
them as illustrated in Figure 4.
IN 1 is used for setup number 5 and OUT 1 is used for setup number 1.
Figure 4: SELECTOR Buttons
The numbers (1 to 8) in Figure 4 that illustrate the corresponding
store/recall configuration numbers are for the purpose of illustration
only and do not actually appear on the buttons.
To store a setup:

For example, press the OUT 3 button and IN 4 button.
You can set any of the IN-OUT buttons
2. Press the STO button.
The STO button flashes.
3. Select an OUT or IN SELECT button to store the machine setup (for
example, IN 2 for preset 6).
4. Press the LOCK button to store the current setup.
In this example, the IN 2 button stores the setup.
Press the LOCK button within 10 seconds as the store operation times out
automatically after this period.
To recall a setup:

6.4 Changing the Port Switching Speed
The switching speed can be set per port to any of the following:
3—Normal (default)
2—Fast
1—Extra fast
To change the port switching speed:
1. Ensure that the device is in normal switching mode, (that is, not Store,
Recall or EDID mode).
2. Press the RCL and EDID buttons at the same time.
The RCL and EDID buttons flash, and the display indicates the switching
speed mode of each port.
IN 1, IN 2 and IN 3 are illuminated (red).
3. Press one or more (or ALL) of the OUT buttons to select the port to change.
The selected port setting on the LED display flashes.
4. Press one of the IN 1/IN 2/IN 3 button to toggle the switching speed, (to Extra
fast/Fast/Normal, respectively).
The switching speed displayed changes for the selected ports.
5. Press the LOCK button to confirm the change.
The switching speed for the selected port is changed and the device reverts
to the normal switching mode.
Note: If the LOCK button is not pressed within about 12 seconds, the device exits
the port speed switching mode automatically and all changes are lost.
6.5 Setting HDCP to On/Off
HDCP support can be enabled (On) or disabled (Off) for each of the HDMI inputs,
allowing the source to transmit a non-HDCP signal if required (for example, when
working with a Mac computer)
To set the HDCP:

14
VS-44HDCP - Operating the VS-44HDCP 4x4 DVI Matrix Switcher
1. Turn the power off on the machine.
2. Press and hold the IN 1, IN 2 and LOCK buttons simultaneously and turn the
power on while pressing these buttons (you will need more than one person
to perform this step).
The machine is set to the HDCP enable/disable mode.
The input front panel buttons’ status indicates the HDCP state of each input:
HDCP enabled (ON) on an input –that input button is illuminated
HDCP disabled (OFF) on an input –that button is not illuminated
3. Press an input button to change its status.
You can press one or more inputs.
4. Once you have changed the status of HDCP on the inputs as desired, press
the EDID to save the changes and exit the HDCP enable/disable mode to
return to normal operation.
Note: If the EDID button is not pressed within about 12 seconds, the device exits
the port speed switching mode automatically and all changes are lost.
6.6 Switching Between Protocol 2000 and Protocol 3000
To switch from Protocol 2000 to Protocol 3000 and vice-versa using the front
panel buttons:
Press Output buttons 1 and 3 at the same time.
Protocol 3000 is active.
Press Output buttons 1 and 2 at the same time.
Protocol 2000 is active.
Note that when sending consecutive protocol commands make sure to
maintain at least a 200ms delay between commands.
After performing EDID get/store commands, a 1 sec delay is required
before sending another protocol command.
