2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.

Overview
3
3 Overview
The VS-66HDMI is a high quality 6x6 matrix switcher for HDMI signals.
In particular, the VS-66HDMI:
Supports up to 1.65Gbps bandwidth per graphic channel
1
Supports HDCP (High Definition Digital Content Protection)
Includes an OFF button to disconnect an output
Includes a PANEL LOCK button to prevent unwanted tampering with the
buttons on the front panel
Has 12 preset memory locations for quick access to common configurations
Fits into one vertical space of a standard 19” professional rack enclosure
Control the VS-66HDMI using the front panel buttons, or remotely via:
RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
The Kramer infra-red remote control transmitter
The ETHERNET
An external remote IR receiver (optional), see section 4.1
3.1 Defining EDID
The Extended Display Identification Data (EDID
2
) is a data-structure,
provided by a display, to describe its capabilities to an HDMI source. The
EDID enables the VS-66HDMI 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. See section 7.1 for details
of how to acquire the EDID.
3.2 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
3
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
4
and an HDCP Licensee
5
.
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
2 Defined by a standard published by the Video Electronics Standards Association (VESA)
3 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
4 See http://www.hdmi.org/about/adopters_founders.asp
5 See http://www.digital-cp.com/list/

Overview
KRAMER: SIMPLE CREATIVE TECHNOLOGY
4
In particular, HDMI
1
:
Provides a simple
2
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
3
cable
Supports standard, enhanced, high-definition video, and multi-channel
digital audio
4
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
5
, 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), standard definition formats such as NTSC or
PAL, as well as 480p and 576p.
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 VS-66HDMI away from moisture, excessive sunlight and dust
1 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI
licensing LLC
2 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
3 HDMI technology has been designed to use standard copper cable construction at up to 15m
4 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
5 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

. The external IR receiver can be located up to 15 meters away from
the machine. This distance can be extended to up to 60 meters when used
with three extension cables
2
.
Before using the external IR receiver, be sure to arrange for your Kramer
dealer to insert the internal IR connection cable
3
with the 3.5mm connector
that fits into the REMOTE IR opening on the rear panel.
Connect the external IRreceiver to the REMOTE IR 3.5mm connector.

5 Installing the VS-66HDMI 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 to supply
connections other than direct connections to the
branch circuit (for example, the use of power strips),
and that you use only the power cord that is supplied
with the machine.

When switching (ie. instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched.
Similarly, if switching is done via the machine’s front-panel, then these bits are set with the INPUT NUMBER which was
switched. For other operations, these bits are defined according to the table.
