Overview
The Kramer VM-2HDCP is an HDCP (High-Bandwidth Digital Content
signals. Since high-resolution DVI signals are very sensitive to cable quality
and to PCB layout, the VM-2HDCP uses a uniquely designed PCB which
includes all buffering, conditioning and amplifying circuitry to provide two
high-level output signals.
In particular, the VM-2HDCP:
•
Distributes signals having resolutions up to UXGA, including all
HDTV formats
•
•
•
Has a bandwidth of 1.65GHz
Supports the DDWG DVI 1.0 standard
Consists of a built-in re-clocking block that re-generates the DVI
signal, so that several units may be cascaded
•
from one of the outputs, so it can then provide the EDID
information to the DVI source even if the display device is not
connected
•
Has I-EDIDPro™ Kramer Intelligent EDID Processing™, an
intelligent EDID handling and processing algorithm that ensures
Plug and Play operation for DVI systems
•
•
Has three DVI-I connectors, which are compatible with all types
of DVI cables
Is a cost-effective solution for distributing the TMDS signals used
for DVI, and uses state-of-the-art line drivers on both outputs
3.1 About HDCP
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.

Overview
3.2 Defining EDID
provided by a display, to describe its capabilities to the source. The EDID
enables the VM-2HDCP 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.
3.3 Recommendations for Best Performance
Achieving the best performance means:
•
Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching,
and elevated noise levels (often associated with low quality
cables)
•
Avoiding interference from neighboring electrical appliances and
positioning your VM-2HDCP away from moisture, excessive
sunlight and dust

.
.
OUTPUT 1 connector to DVI acceptor 1 (for example, a
projector)
OUTPUT 2 connector to DVI acceptor 2 (for example, a display)
3. Connect the 12V DC power adapter (wall transformer) to the 12V DC
socket and connect the transformer to the mains electricity.

5.1 Acquiring the EDID
you connect the power before connecting either of the acceptors or the
source.
You can acquire:
•
•
The Default EDID (both output LEDs blink)
The EDID from One Output (the relevant output illuminates)
You can also acquire the Clone EDID which copies the EDID data from the
acceptor bit-by-bit.

5.1.1 Acquiring/Changing the EDID
You can work with the default EDID or acquire or change an EDID via one
of the connected outputs. Use the EDID Setup button to acquire the output
EDID information.
To acquire or change the EDID of a new output display:
1. Connect the power supply.
The ON LED lights.
2. Connect the new output display device.
3. Press and hold the EDID button for more than three seconds and release.
The INPUT LED blinks and the OUT 1 LED and OUT 2 LED blink
alternately.
4. Press the EDID button again when the appropriate OUT LED lights, that is,
to copy the EDID from the display connected to the DVI:
.
OUT 1 connector, press the EDID button when the OUT1
LED is on
.
OUT 2 connector, press the EDID button when the OUT2
LED is on
In either case, the VM-2HDCP copies the EDID from the display. If no
display is connected to the selected DVI output, the default EDID will be
chosen.
Note that during the EDID setup, the respective OUT LED blinks. When that
output is connected, that OUT LED illuminates
5.1.2 Acquiring the Clone EDID
1. Connect the new output display device (for example, to OUT 1).
2. Disconnect the power supply.
3. Reconnect the power supply while pressing the EDID button.
The ON LED lights and the OUT 1 and OUT 2 blink alternately.
4. Release the EDID button when the OUT 1 LED blinks.
The Clone EDID is stored in the non-volatile memory when the OUT 1
LED ceases to blink.
1 This example refers to OUT 1. The same applies for OUT 2 if the acceptor is connected to OUT 2
