3 Overview
The Kramer VM-8HDMI 1:8 HDMI Distributor and the VM-16HDMI 1:16
HDMI Distributor are high quality distributors that accept an HDMI input and
distribute the signal to 8/16 outputs respectively, allowing one or more of the
outputs to be connected to receiving devices, thus making them a versatile,
reliable component in a video system. The VM-8HDMI /VM-16HDMI
distribute signals having resolutions up to UXGA, including all HDTV formats.
In particular, the HDMI distributors:
 Support up to 1.65Gbps bandwidth per graphic channel
1
 Equalize and reclock the data
 Feature a default EDID
2
for fast and efficient connection of the unit
3
 Can read and store, in non-volatile memory, the EDID block from one of
the outputs, so it can then provide the EDID information to the HDMI
source even if the display device is not connected
 Include HDMI connectors
4
, output status LEDs
4
, and EDID read and
select buttons
The HDMI distributors are housed in a 19" 1U rack-mountable enclosure, and
are fed from a 100-264 VAC universal switching power supply.
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
2 EDID is Extended Display Identification Data
3 The default EDID feature lets you connect the VM-8HDMI/VM-16HDMI without having to connect a display to the output

3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
1
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality. Note
that Kramer Electronics Limited is an HDMI Adopter
2
and an HDCP Licensee
3
.
In particular, HDMI:
 Provides a simple
4
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
5
cable
 Supports standard, enhanced, high-definition video, and multi-channel
digital audio
6
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
 Benefits consumers by providing superior, uncompressed digital video
quality via a single cable
7
, 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/50/60), as
well as standard definition formats such as NTSC or PAL
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
2 See http://www.hdmi.org/about/adopters_founders.asp
3 See http://www.digital-cp.com/list/
4 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
5 HDMI technology has been designed to use standard copper cable construction at up to 15m
6 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
7 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

3.2 Defining EDID
The Extended Display Identification Data (EDID
1
) 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-8HDMI/
VM-16HDMI 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 HDMI distributors away from moisture, excessive sunlight and dust

5 Installing the VM8HDMI / VM-16HDMI on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
5 to 65% RHL, non-condensing
-20 to +70 Deg. Centigrade
5 to 95% RHL, non-condensing
Operating humidity range
Storage temperature range
Storage humidity range
When installing on a 19" rack, avoid hazards by taking
care that:
It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the machine
(3 on each side), and replace those
screws through the ear brackets.
Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided) through
each of the four holes in the rack
ears.
Note that:
Detachable rack ears can be removed
for desktop use
Always mount the machine in the rack
before you attach any cables or
connect the machine to the power
If you are using a Kramer rack adapter
kit (for a machine that is not 19"), see
the Rack Adapters user manual for
installation instructions (you can
download it at:
http://www.kramerelectronics.com)




In some models, the front panel
may feature built-in rack ears
Once rack mounted, enough air will still flow around the
machine.
The machine is placed straight in the correct horizontal
position.
You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the product
label.
The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention
and that you use only the power cord that is
supplied with the machine.
to situations where
electricity is supplied indirectly (when the power cord is
not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip,

6.1 Acquiring the EDID
The VM-8HDMI initially operates with the default EDID. This means that you
can turn ON the power before connecting any of the acceptors or the source.
6.1.1 Acquiring the EDID from a Selected Output
You can either work with the default EDID or select an EDID from one of the
connected outputs.
To select an EDID, do the following:
1. Press the SELECT button.
The connected OUTPUTS LEDs blink.
2. Press the SELECT button again to cycle from one output to another until
reaching the desired output
1
.
To reset the default EDID, select a disconnected output
3. Press the READ button.
The blinking ceases and the button illuminates. The VM-8HDMI accesses the
EDID of the selected output.
The EDID of the selected output is stored in the non-volatile memory when
the READ button no longer illuminates.
