3.1
Defining EDID
The Extended Display Identification Data (EDID) is a data-structure provided by a
display, to describe its capabilities to a graphics card (that is connected to the
display’s 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.
EDID is defined by a standard published by the Video Electronics Standards
Association (VESA).
3.2
About HDMI—General Description
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
audio/video interface, widely supported in the entertainment and home cinema
industry. HDMI ensures an all-digital rendering of video without the losses associated
with analog interfaces and their unnecessary digital-to-analog conversions. It delivers
the maximum high-definition image and sound quality in use today. Note that Kramer
Electronics Limited is an HDMI Adopter and an HDCP Licensee.
HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered
trademarks of HDMI licensing LLC.
In particular, HDMI:
•
Provides a simple interface between any audio/video source, such as a set-
top box, DVD player, or AV receiver and video monitor, such as a digital flat
LCD / plasma television (DTV), over a single lengthy cable
SIMPLICITY - With video and multi-channel audio combined into a single cable, the cost,
complexity, and confusion of multiple cables currently used in AV systems is reduced
LENGTHY CABLE - HDMI technology has been designed to use standard copper cable
construction at up to 15m
•
•
Supports standard, enhanced, high-definition video, and multi-channel digital
audio on a single cable
MULTI-CHANNEL DIGITAL AUDIO - 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
Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
4
VS-81H - Overview
•
Benefits consumers by providing superior, uncompressed digital video quality
via a single cable, and user-friendly connector
HDMI provides the quality and functionality of a digital interface while also supporting
uncompressed video formats in a simple, cost-effective manner
•
•
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), standard definition formats such as NTSC or PAL, as well as
480p and 576p
3.3
About HDCP—General Description
The High-Bandwidth Digital Content Protection (HDCP) standard developed by
Intel, 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.

6.1
The PC and DVD Modes
The VS-81H has two operation modes that can be set individually for each input:
the PC mode (default) and the DVD mode:
•
Use the PC mode when connecting one or more computers to the inputs
using a DVI-to-HDMI converter cable
For example, the Kramer HDMI-DVI gold-plated cable in various lengths (3”, 6”, 10” and
15”).
•
Use the DVD mode when connecting one or more DVDs to the inputs
In the PC mode, an input always has access to the EDID (default or acquired) to
prevent the computer from resetting if the output is not connected.
In the DVD mode, an input only has access to the EDID when it is switched to the
connected output.
The PC mode and the DVD mode can be applied to a single unit or to several
inputs. For example, if you want to connect computers to INPUTS 1 and 2, and
DVD machines to INPUTS 6 and 8, set INPUTS 1 and 2 to the PC mode and
INPUTS 6 and 8 to the DVD mode.
To set the inputs to either the PC or DVD mode, do the following:
1. Turn off the VS-81H POWER.
2. Press the PANEL LOCK button while turning the POWER on again.

1st BYTE:
D – “DESTINATION”:
Bit 7 – Defined as 0.
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.
All the values in the table are decimal, unless otherwise stated

IDENTIFY MACHINE
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.
