•Up to 2.25Gbps bandwidth per graphic channel1
•HDTV compatibility and HDCP compliance
•I-EDIDPro™ Kramer Intelligent EDID Processing™, an
intelligent EDID handling and processing algorithm that ensures
Plug and Play operation for DVI systems
•Acquisition of the EDID from one output, from several connected
outputs (Auto-mix) or it acquires the default EDID for fast and
efficient connection of the unit2
•A 19" 1U rack mountable enclosure and is fed from a 100-240
VAC universal switching power supply
Control the VM-24HDCP via:
•The front panel buttons
•The infrared remote control transmitter, RC-IR3
•The infrared remote extension cable transmitter, see section 4.1
•RS-232 serial commands transmitted by a touch screen system,
PC, or other serial controller
3.1 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard3
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.
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
2 Lets you use the EDID default value when no display from which to read the EDID is connected

3.2 Defining EDID
The Extended Display Identification Data (EDID1
3.3 Recommendations for Best Performance
) is a data-structure,
provided by a display, to describe its capabilities to an HDCP source. The
EDID enables the VM-24HDCP 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.
To achieve the best performance:
•Connect only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching,
and elevated noise levels (often associated with low quality
cables)
•Avoid interference from neighboring electrical appliances and
position your VM-24HDCP away from moisture, excessive
sunlight and dust

8 Communication Protocol
The VM-24HDCP 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 (i.e. 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 (i.e. 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
i.e. 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.
