distributes the selected signal to four outputs.
The VM-24HDMI:
Supports up to 2.25Gbps bandwidth per graphic channel
1
Has the ability to read and store, in non-volatile memory
2
, the EDID3 block
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
Lets you acquire the EDID from one output, from several connected
outputs (Auto-mix) or acquire the default EDID for fast and efficient
connection of the unit4
Is housed in a 19" 1U rack mountable enclosure and is fed from a 100-240
VAC universal switching power supply
Control the VM-24HDMI via:
The front panel buttons

RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital5
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality.
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 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
5 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions

In particular, HDMI1:
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 lengthy3 cable
Supports standard, enhanced, high-definition video, and multi-channel
digital audio4 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 cable5, 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
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 (EDID6) is a data-structure,
provided by a display, to describe its capabilities to an HDMI source. The
EDID enables the VM-24HDMI 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.
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
6 Defined by a standard published by the Video Electronics Standards Association (VESA)

5 Installing in a Rack
This section describes what to do before installing in a rack and how to rack
mount.
Before Installing in a Rack
How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5° to +45° C (41° to 113° F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20° to +70° C (-4° to 158° F)
Storage humidity range 5 to 95% RHL, non-condensing
CAUTION!!
When installing in 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

8 Communication Protocol
The VM-24HDMI is compatible with Kramer’s Protocol 2000 (version 0.50)
(below). This RS-232/RS-485 communication protocol uses four bytes of
information as defined below. For RS-232, a null-modem connection between
the machine and controller is used. The default data rate is 9600 baud, with
no parity, 8 data bits and 1 stop bit.

1st BYTE: Bit 7 – Defined as 0.
D – “DESTINATION”: 0 - for sending information to the switchers (from the PC);
1 - for sending to the PC (from the switcher).
N5…N0 – “INSTRUCTION”
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a function is
performed via the machine’s keyboard, then these bits are set with the INSTRUCTION NO., which was performed. The
instruction codes are defined according to the table below (INSTRUCTION NO. is the value to be set for N5…N0).
2nd BYTE: Bit 7 – Defined as 1.
I6…I0 – “INPUT”.
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.
3rd BYTE: Bit 7 – Defined as 1.
O6…O0 – “OUTPUT”.
When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched.
Similarly, if switching is done via the machine’s front-panel, then these bits are set with the OUTPUT NUMBER which was
switched. For other operations, these bits are defined according to the table.
4th BYTE: Bit 7 – Defined as 1.
Bit 5 – Don’t care.
OVR – Machine number override.
M4…M0 – MACHINE NUMBER.
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 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 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.
