manuals, application programs (where appropriate), and to check if
firmware upgrades are available.
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer VS-41HDCP away from moisture, excessive sunlight
and dust
!
Caution: No operator serviceable parts inside the unit
Warning: Use only the Kramer Electronics input power wall
adapter that is provided with the unit
Warning: Disconnect the power and unplug the unit from the wall
before installing

3 Overview
The VS-41HDCP is a high quality 4x1 switcher for DVI signals that supports up to
2.25Gbps bandwidth per graphic channel (suitable for resolutions up to UXGA at
60Hz, and for all HD resolutions). It equalizes the signal and switches one of the
four inputs to a single DVI output.
In particular, the VS-41HDCP:
•Is HDCP (High Definition Digital Content Protection) compliant
•Has four input selector buttons
•Includes a MUTE button to disconnect the output and a PANEL LOCK button
to prevent unwanted tampering with the buttons on the front panel
•Features a USB connector for setup and programming
•Features EDID PassThru. Passes EDID/HDCP signals from source to
display
•Features enhanced EDID (Extended Display Identification Data) - The unit
can store and recall an EDID setting in non-volatile memory from either the
default EDID or a connected output, allowing convenient and reliable
connection to the source
•Is compact in size. Two units can be rack mounted side-by-side in a 1U rack
space with the optional Kramer RK-1 rack kit
Control the VS-41HDCP using the front panel buttons, or remotely via:
•RS-232 serial commands (using Kramer 2000 and 3000 Protocols)
transmitted by a touch screen system, PC, or other serial controller
•The Kramer infrared remote control transmitter
•The ETHERNET
•Remote control contact closure

4 VS-41HDCP - Overview
3.1 Defining EDID
The Extended Display Identification Data (EDID) is a data-structure provided by a
display, to describe its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the VS-41HDCP to “know” what kind of
monitor is connected to the output. The EDID includes the manufacturer’s name,
the product type, the timing data supported by the display, the display size,
luminance data and (for digital displays only) the pixel mapping data.
EDID is defined by a standard published by the Video Electronics Standards
Association (VESA).
3.2 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard developed by Intel
protects digital video and audio signals transmitted over DVI or HDMI connections
between two HDCP-enabled devices to eliminate the reproduction of copyrighted
material. To protect copyright holders (such as movie studios) from having their
programs copied and shared, the HDCP standard provides for the secure and
encrypted transmission of digital signals.

Always switch off the power to each device before connecting it to your
VS-41HDCP. After connecting your VS-41HDCP, connect its power and
then switch on the power to each device.
To connect the VS-41HDCP 4x1 DVI Switcher (as illustrated in Figure 3), do the
following:
1. Connect up to four computer graphics sources to the inputs (1 to 4).
You do not have to connect all the DVI sources.
2. Connect the OUTPUT DVI connector to a DVI acceptor (for example, a
display).
3. If required, connect a PC and/or controller to the RS-232 port and/or the
ETHERNET port (see Section 6.4).
4. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 3).
5. If required, acquire the EDID (see Section 6.1).
Press an INPUT SELECTOR button (from 1 to 4) to choose which DVI input to
route to the output.

5.1 Connecting to the VS-41HDCP via RS-232
You can connect to the VS-41HDCP via an RS-232 connection using, for example,
a PC. Note that a null-modem adapter/connection is not required.
To connect to the VS-41HDCP via RS-232:
•Connect the RS-232 9-pin D-sub rear panel port on the VS-41HDCP unit via
a 9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5
need to be connected) to the RS-232 9-pin D-sub port on your PC
