RS-232 serial commands transmitted by a touch-screen system,
PC, or other serial controller
The Kramer infra-red remote control transmitter
The ETHERNET
To achieve the best performance:
Use only good quality connection cables2 to avoid 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 that
may adversely influence signal quality and position your Kramer
VS-44HDMI away from moisture, excessive sunlight and dust
3.1 Defining the EDID
The EDID (Extended Display Identification Data3) is a data-structure,
provided by a display, to describe its capabilities to an HDMI source. The
EDID enables the VS-44HDMI to “know” what kind of monitor is
connected to the output. The EDID includes the name of the manufacturer,
the product type, the timing data supported by the display, the display size,
luminance data and (for digital displays only) the pixel mapping data.

3.2 About HDMI
HDMI (High-Definition Multimedia Interface) is an uncompressed
all-digital1 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 Adopter2
and an HDCP Licensee3.
HDMI features:
A simple4 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
long5 cable
A standard, enhanced, high-definition video, and multi-channel
digital audio6 on a single cable
8-channel digital audio, with spare bandwidth to accommodate future
enhancements and compliance with all ATSC HDTV standards
Superior, uncompressed digital video quality via a single cable7,
and user-friendly connector
Backward-compatibility with DVI (Digital Visual Interface)
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
Support for existing high-definition video formats (720p, 1080i,
and 1080p/60), standard definition formats such as NTSC or PAL,
as well as 480p and 576p
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digitalto-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

5 Installing the VS-44HDMI in a Rack
This section describes how to install the VS-44HDMI in a rack.
Before Installing on a Rack
How to Rack Mount
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5º to +45º C (41º to 113º F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20º to +70º C (-4º to 158º F)
Storage humidity range 5 to 95% RHL, non-condensing
CAUTION!!
When installing on a 19" rack, avoid hazards by taking
care that:
1. 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.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. 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.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention 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, and that you use only the power cord that is
supplied with the machine.
To rack-mount a machine:
1. 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.
2. 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:
In some models, the front panel
may feature built-in rack ears
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

Kramer Protocol 2000
19
Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial
port, they are usually configured together with each machine having an individual machine number. If the OVR bit is set, then
all machine numbers will accept (implement) the command, and the addressed machine will reply.
For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is
configured as MACHINE NUMBER = 1.

NOTES on the above table:
NOTE 1 - When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is sent to
the switchers, it will reset according to the present power-down settings.
NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if
the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the
HEX code
01 85 88 83
was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8. If the user switched input 1 to output 7
via the front panel keypad, then the switcher will send HEX codes:
41 81 87 83
to the PC.
When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by
sending to the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION bit is set high).
NOTE 3 - SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory, (i.e. those
used for Store and Recall).

NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are
returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are as per
the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is breakaway
setting, then the reply to the HEX code
0B 80 80 85
would be HEX codes
4B 80 81 85
NOTE 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not
defined / no valid input is detected; or 1 if it is defined / valid input is detected.
NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1, 2,
5 or 7, the machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216,
the reply to the request to send the audio machine name would be (HEX codes):
7D 96 90 81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).
If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine will send its software version
number. Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number in
front of the decimal point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to the
request to send the version number would be (HEX codes):
7D 83 85 81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 5dec for 3rd byte).
If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine’s name is sent. For example, for the
VS-7588YC, the reply to the request to send the first suffix would be (HEX codes):
7D D9 C3 81 (i.e. 128dec+ ASCII for “Y” ; 128dec+ ASCII for “C” ).
NOTE 14 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system. For
example, if six 16X16 matrices are configured to make a 48X32 system (48 inputs, 32 outputs), the reply to the HEX code
3E 82 81 82 (ie. request the number of outputs)
would be HEX codes
7E 82 90 82
ie. 16 outputs
NOTE 15 – When the OVR bit (4th byte) is set, then the “video” commands have universal meaning. For example,
instruction 1 (SWITCH VIDEO) will cause all units (including audio, data, etc.) to switch. Similarly, if a machine is in
“FOLLOW” mode, it will perform any “video” instruction.
NOTE 16 - The reply to the “REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 4 above, except that here the
OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.
