3 Overview
The high quality VM-2HDMI accepts an HDMI input and distributes the
signal to two outputs. In particular, the VM-2HDMI:
Supports up to 1.65Gbps bandwidth per graphic channel
1
Can read and store, in non-volatile memory
2
, the EDID
3
block from either
of the output display devices, so it can then provide the EDID information
to the HDMI source even if the display device is not connected
Has a default EDID for fast and efficient connection of the unit
4
Is 12VDC fed
3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
5
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality.
In particular, HDMI
6
:
Provides a simple
7
interface between any audio/video source, such as a
set-top box, DVD player, or A/V receiver and video monitor, such as a
digital flat LCD / plasma television (DTV), over a single lengthy
8
cable
Supports standard, enhanced, high-definition video, and multi-channel
digital audio
9
on a single cable
Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
2 While the machine is ON
3 EDID is Extended Display Identification Data (see section 5.2 for a detailed definition)
4 Lets you use the EDID default value when no display from which to read the EDID is connected
5 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
6 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI
licensing LLC
7 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
8 HDMI technology has been designed to use standard copper cable construction at up to 15m
9 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats

KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview

Benefits consumers by providing superior, uncompressed digital video
quality via a single cable
1
, and user-friendly connector
Is backward-compatible with DVI (Digital Visual Interface)
Supports two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such
as automatic configuration and one-button play
HDMI has the capacity to support:
Existing high-definition video formats (720p, 1080i, and 1080p/60), as
well as standard definition formats such as NTSC or PAL
3.2 Defining EDID
The Extended Display Identification Data (EDID
2
) 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 VM-2HDMI 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
To achieve the best performance:
Connect 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)
Avoid interference from neighboring electrical appliances and position
your VM-2HDMI away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
3
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
1 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner
2 Defined by a standard published by the Video Electronics Standards Association (VESA)

5 Using the VM-2HDMI 1:2 HDMI Distributor
This section describes how to connect the VM-2HDMI (see section 5.1) and
how to use the EDID SETUP button (see section 5.2).
5.1 Connecting the VM-2HDMI 1:2 HDMI Distributor
To connect the VM-2HDMI, as the example in Figure 3 shows, do the
following
1
:
1. Connect the HDMI source (for example, a DVD) to the HDMI IN
connector.
2. Connect the HDMI OUT connectors
2
to up to 2 HDMI acceptors, as
follows:
HDMI OUT1 connector to HDMI acceptor 1 (for example, an LCD
TV)
HDMI OUT2 connector to HDMI acceptor 2 (for example, a plasma
display)
3. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
4. Press the EDID SETUP button to acquire or change the EDID
information (see section 5.2).
1 Switch OFF the power on each device before connecting it to your VM-2HDMI. After connecting your VM-2HDMI, switch
on its power and then switch on the power on each device
2 If you are using only one HDMI acceptor, you should connect it to OUT 1

5.2 Using the VM-2HDMI EDID SETUP Button
Initially, the VM-2HDMI operates with the factory default EDID
1
. This lets
you connect the power before connecting either of the acceptors or the source.
You can acquire the EDID From:
The Default EDID (both output LEDs blink)
One Output (the relevant output illuminates)
You can also acquire the Clone EDID which copies the EDID data from the
acceptor bit-by-bit.
1 The VM-2HDMI reads the EDID, which is stored in the non-volatile memory

5.2.1 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 SETUP button for more than three seconds and
release.
The INPUT LED blinks and the OUT2 LED and OUT1 LED blink alternately.
4. Press the EDID SETUP button again when the appropriate OUT LED
lights, that is to copy the EDID from the display connected to the HDMI:
OUT1 connector, press the EDID button when the OUT1 LED is on
OUT2 connector, press the EDID button when the OUT2 LED is on
In either case, the VM-2HDMI copies the EDID from the display. If no
display is connected to the selected HDMI 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
5.2.2 Acquiring the Clone EDID
To acquire the Clone EDID, do the following
1
:
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 SETUP button.
The ON LED lights and the OUT 1 and OUT 2 blink alternately.
4. Release the EDID SETUP 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
