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

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

8 VS-41HDCP - Operating the VS-41HDCP
6 Operating the VS-41HDCP
This section describes how to:
•Operate the PC and DVD modes (see Section Section 6.1)
•Acquire the EDID (see Section 6.2)
•Control the machine via the REMOTE terminal block connector (see Section 6.3)
•Control the machine via the ETHERNET port (see Section 6.4)
•Control the machine via the Web pages (see Section 6.5)
6.1 The PC and DVD Modes
The VS-41HDCP has two operation modes that are specific per input: the PC mode
(which is the factory default) and the DVD mode. The PC mode is used when
connecting a computer or several computers to one or more of the inputs. The DVD
mode is used when connecting a DVD or several DVDs to the inputs.
The PC mode and the DVD mode can be applied to a single input or to several
inputs. For example, if you want to connect a computer to INPUT 1, another
computer to INPUT 2, and DVD machines to INPUT 3 and INPUT 4, set INPUT 1
and INPUT 2 to the PC mode and INPUT 3 and INPUT 4 to the DVD mode.
To set the inputs to either the PC or DVD mode, do the following:
1. Turn off the POWER.
2. Press the PANEL LOCK button while turning the POWER on again.
3. Keep pressing and holding the PANEL LOCK button for a few seconds and
then release it.
The LOCK button blinks.
If an input button illuminates, this indicates that that input is set to the DVD
mode.
If an input button is not illuminated, this indicates that that input is set to the
PC mode.

4. Toggle between the PC mode (input button not illuminated) and the DVD
mode (input button illuminated) by pressing that input.
5. Press the PANEL LOCK button to exit this mode.
The following table summarizes the differences between the PC mode and the DVD
mode:
PC Mode
DVD Mode
The input is connected to a computer The input is connected to a multimedia application,
such as a DVD, a set top box and so on
The EDID is available at all times (to prevent
computer reset)
The EDID is available only when that input is
connected to an output
The input EDID source is the default EDID or
an acquired EDID (see Section 6.1)
The input EDID source is acquired directly from
the connected output
Note, that even if an input is set to the PC mode, you can connect a DVD player to
that input and vice versa, a PC can be connected to an input that was set to the
DVD mode.
6.2 Setting the EDID
You can acquire or change the EDID (see Section 6.2.1) or reset the machine to the
default EDID (see Section 6.2.2).
If the connected output (for which EDID has already been acquired) is
disconnected, the EDID button blinks and then ceases blinking when reconnecting
the same output. When a new output is connected the EDID button blinks to
indicate that new EDID information must be acquired.

6.2.1 Acquiring / Changing the EDID
You can work with the default EDID or acquire or change an EDID via the
connected output. Use the EDID button to acquire the output EDID information.
To acquire or change the EDID of a new output display:
1. Connect the power supply.
2. Connect the new output display device.
The EDID button blinks.
3. Press the EDID button.
The INPUT buttons blink in sequence until the EDID is acquired.
6.2.2 Resetting the Default EDID
To reset the default EDID, disconnect the output and repeat the steps in Section
6.2.1.
6.3 Controlling via the REMOTE Terminal Block Connector
The contact closure remote control pins operate in a similar way to the INPUT
SELECTOR button. Using the contact closure remote control you can select the
DVI input. To do so, momentarily connect the required input pin (IN 1, IN2, IN 3 or
IN 4) on the REMOTE terminal block connector to the GND (Ground) pin, as Figure
4illustrates.
