3.1 Defining EDID  
The Extended Display Identification Data (EDID3) is a data-structure,  
provided by a display, to describe its capabilities to an HDMI source. The  
EDID enables the VS-42H 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 From INPUT 1 to INPUT 4, TO OUTPUT 1 and from INPUT 1 to OUTPUT 4, TO OUTPUT 2

Overview  
3.2 About HDMI  
High-Definition Multimedia Interface (HDMI) 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 Adopter  
and an HDCP Licensee.  
In particular, HDMI2:  
Provides a simple3 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 lengthy4  
cable  
Supports standard, enhanced, high-definition video, and multi-channel  
digital audio5 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 cable6, and user-friendly connector  
Is backward-compatible with DVI (Digital Visual Interface)  
Supports CEC, 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, 2K and 4K), standard definition formats such as  
NTSC or PAL, as well as 480p and 576.  
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-  
to-analog conversions  
2 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI  
licensing LLC  
3 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  
4 HDMI technology has been designed to use standard copper cable construction at up to 15m  
5 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  
6 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a  
simple, cost-effective manner

Kramer Protocol 2000  
10 Kramer Protocol 2000  
The VS-42H is compatible with Kramer’s Protocol 20001 (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.

4th byte  
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 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 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.
