3.1 Defining EDID

The Extended Display Identification Data (EDID2) 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-digital3
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 Adopter4 and an HDCP Licensee5.

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 digital­to-analog conversions

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.

switched. For other operations, these bits are defined according to the table.

th

BYTE: Bit 7 – Defined as 1.
Bit 5 – Don’t care.
OVR – Machine number override.
M4…M0 – MACHINE NUMBER.

section on our Web site at: http://www.kramerelectronics.com
2 The instruction codes in Table 5 are a sub-set of the Protocol 2000. You can find the full protocol on our Web site at
http://www.kramerelectronics.com

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

Kramer Protocol 2000

KRAMER: SIMPLE CREATIVE TECHNOLOGY

20

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.
