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-81H 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 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)

3.2 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all digital1
In particular, HDMI:
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 and an HDCP Licensee.
•Provides a simple2interface 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
•Supports standard, enhanced, high-definition video, and multi-
channel digital audio
cable
4
•Transmits all ATSC HDTV standards and supports 8-channel digital
audio, with bandwidth to spare to accommodate future enhancements
and requirements
on a single cable
•Benefits consumers by providing superior, uncompressed digital
video quality via a single cable5
•Is backward-compatible with DVI (Digital Visual Interface)
, and user-friendly connector
•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), as well as standard definition formats such as
NTSC or PAL.
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
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

3.3 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard1
3.4 Recommendations for Best Performance
, protects
digital video and audio signals transmitted over DVI or HDMI connections
between two HDCP-enabled devices to eliminate the reproduction of
copyrighted material. To protect copyright holders (such as movie studios)
from having their programs copied and shared, the HDCP standard provides
for the secure and encrypted transmission of digital signals.
To achieve the best performance:
•Use only good quality connection cables2
•Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
VS-81H away from moisture, excessive sunlight and dust
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).

7.1 The PC and DVD Modes
The VS-81H has two operation modes that are specific per input: the PC
mode1
•The PC mode is used when connecting a computer or several
computers to one or more of the inputs via a DVI-to-HDMI
converter cable
and the DVD mode:
2
•The DVD mode is used when connecting a DVD or several DVDs
to the inputs
When in the PC mode, the input has access to the EDID (default or
acquired) to prevent the computer from resetting if an output is not
connected. In the DVD mode, the EDID of the connected output is available
only when the input to which the DVD is connected, is switched to the
output.
The PC mode and the DVD mode can be applied to a single input or to
several inputs. For example, if you want to connect a computer to INPUT 1,
another computer to INPUT 2, and DVD machines to all the other inputs
(from INPUT 3 to INPUT 8), set INPUT 1 and INPUT 2 to the PC mode
and all the other inputs to the DVD mode.
To set the inputs to either the PC or the DVD mode, do the following:
1. Turn the POWER off.
2. Press the PANEL LOCK button while turning the POWER on again.
The INPUT buttons blink simultaneously.
3. Keep pressing and holding the PANEL LOCK button for a few seconds and
then release it.
The PANEL LOCK button blinks.
If an input button illuminates, this indicates that that input is set to the DVD
mode.
If an input button is not illuminated, this indicates that that input is set to the
PC mode.
4. Toggle between the PC mode (input button not illuminated) and the DVD
mode (input button illuminated) by pressing that input.
5. Press the PANEL LOCK button to exit this mode.
6. You can connect a computer to the input(s) that is set to the PC mode and a

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 accept (implement) the command, and the addressed machine replies.

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 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.
