Protocol 3000
The VS-44UHD 4x4 UHD Matrix Switcher can be operated using the Kramer Protocol 3000
serial commands. The command framing varies according to how you interface with the
VS-44UHD.
Generally, a basic video input switching command that routes a layer 1 video signal to HDMI
out 1 from HDMI input 2 (ROUTE 1,1,2), is entered as follows:
• Terminal communication software, such as Hercules:
The framing of the command varies according to the terminal communication software.
.
• K-Touch Builder (Kramer software):
• K-Config (Kramer configuration software):
All the examples provided in this section are based on using the K-Config software.
You can enter commands directly using terminal communication software (e.g., Hercules) by
connecting a PC to the serial or Ethernet port on the VS-44UHD. To enter CR press the Enter
key (LF is also sent but is ignored by the command parser).
Commands sent from various non-Kramer controllers (e.g., Crestron) may require special
coding for some characters (such as, /X##). For more information, refer to your controller’s
documentation.

For more information about Protocol 3000 commands, see:
• Understanding Protocol 3000 on page 49.
• Kramer Protocol 3000 Syntax on page 50.
• Protocol 3000 Commands on page 51.
Understanding Protocol 3000
Protocol 3000 commands are structured according to the following:
• Command – A sequence of ASCII letters (A-Z, a-z and -). A command and its parameters
must be separated by at least one space.
• Parameters – A sequence of alphanumeric ASCII characters (0-9, A-Z, a-z and some
special characters for specific commands). Parameters are separated by commas.
• Message string – Every command entered as part of a message string begins with a
message starting character and ends with a message closing character.
A string can contain more than one command. Commands are separated by a pipe (|)
character.
• Message starting character:
▪ # – For host command/query
▪ ~ – For device response
• Device address – K-NET Device ID followed by @ (optional, K-NET only)
• Query sign – ? follows some commands to define a query request
• Message closing character:
▪ CR – Carriage return for host messages (ASCII 13)
▪ CR LF – Carriage return for device messages (ASCII 13) and line-feed (ASCII 10)
• Command chain separator character – Multiple commands can be chained in the same
string. Each command is delimited by a pipe character (|). When chaining commands,
enter the message starting character and the message closing character only at the
beginning and end of the string.
Spaces between parameters or command terms are ignored. Commands in the string do not
execute until the closing character is entered. A separate response is sent for every
command in the chain.

Kramer Protocol 3000 Syntax
The Kramer Protocol 3000 syntax uses the following delimiters:
• CR = Carriage return (ASCII 13 = 0x0D)
• LF = Line feed (ASCII 10 = 0x0A)
• SP = Space (ASCII 32 = 0x20)
Some commands have short name syntax in addition to long name syntax to enable faster
typing. The response is always in long syntax.
The Protocol 3000 syntax is in the following format:
• Host Message Format:
Start
Address (optional)
Body
Delimiter
#
Device_id@
Message
CR
• Simple Command – Command string with only one command without addressing:
Start
Body
Delimiter
#
Command SP
Parameter_1,Parameter_2,…
CR
• Command String – Formal syntax with command concatenation and addressing:
Start
Address
Body
Delimiter
#
Device_id@
Command_1
Parameter1_1,Parameter1_2,…|
Command_2
Parameter2_1,Parameter2_2,…|

Response
~nn@CPEDIDSPsrc_type,src_id,dst_type,dest_bitmapCR LF
Parameters
src_type – EDID source type (usually output): 0 (Input), 1 (Output), 2 (Default EDID)
src_id – for input source: 1 (Input), for output source: 0 (Default EDID source), 1 (Output 1),
2 (Output 2)
dst_type – EDID destination type (usually input): 0 (Input)
dest_bitmap – bitmap representing destination IDs. Format: XXXX…X, where X is hex digit. The
binary form of every hex digit represents corresponding destinations. Setting ‘1’ indicates that
EDID data is copied to this destination. Setting ‘0’ indicates that EDID data is not copied to this
destination.
Response Triggers
Response is sent to the com port from which the Set was received (before execution)
Notes
Destination bitmap size depends on device properties (for 64 inputs it is a 64-bit word)
Example: bitmap 0x0013 means inputs 1, 2 and 5 are loaded with the new EDID.
In this device, if the destination type is input (0), the bitmap size is 8 bit, for example bitmap 0x81
means the inputs 1 and 8 are loaded with the new EDID.
K-Config Example
Copy the EDID data from the Output 1 (EDID source) to the Input:
“#CPEDID 1,1,0,0x1”,0x0D
Copy the EDID data from the default EDID source to the Input:
“#CPEDID 2,0,0,0x1”,0x0D
