3 Overview
The Kramer VM-28H 2 Input 1:8 HDMI Distri but or and VM-216H 2 Input
1:16 HDMI Distributor are high quality distributors that accept one of two
HDMI inputs and distribute the signal to 8/16 outputs, 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-28H / VM-216H distributes
signals having res olu tions up to UXGA (1600x1200), including all HDTV
formats.
Each high quality HDMI Distributor accepts one of two HDMI inputs, and
distributes the selected signal to :
• 8 outputs (the VM-28H)
• 16 outputs (the VM-216H)
Both machines—the VM-28H and VM-216H:
• Support up to 2.25Gbps bandwidth per graphic channel

• Can read and store, in non-volatile memory

• Let you acquire the EDID from one output, from several connected outputs
or acquire the default EDID for fast and efficient connection of the unit
block, for each
input separately, from an output display device, so it can then provide the
EDID information to the HDMI source even if the display device is not
connected
4
• Have a 19" 1U rack-mountable enc l osure, and are fed from a 100-240 VAC
universal switching power supply
1 Suitable for resolutions up to UXGA (1600x1200) at 60Hz, and for all HD resolutions
2 While the machine is ON
3 EDID is Extended Display Identification Data (see section 3 1 for a detailed definition)
4 Lets you use the EDID default value when no display from which to read the EDID is connected

HDMI has the capacity to support:
• Existing high-definition video formats (720p, 1080i, an d 1080p/ 60), as well
as standard definit i on forma ts such as NTSC or PAL

3 With video and multi-channel audio combined into a single cable, the cost, co mplexity, and confusion of multiple cables
currently used in A/V systems is reduced
4 HDMI technology has been designed to use standard copper cable construction at up to 15m
5 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
6 HDM I 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
3.3 Recommendatio n s for Best Performance
) is a data-structure, provided
by a display, to describe its capabilities to an HDMI source. The EDID enables
the VM-28H / VM-216H 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 displ ay siz e, lum inanc e da ta and (for
digital displays only) the pixel mapping dat a.
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)
• Do not secure the cables in tight bundles or roll the slack into tight coils
• Avoi d interf er ence from ne ighboring electrical applian ces and position your
VM-28H / VM-216H away from moisture, excessive sunlight and dust
