Protocol 3000

The VS-44UHDA 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-44UHDA.

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-44UHDA. 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 56
• Kramer Protocol 3000 Syntax on page 57
• Protocol 3000 Commands on page 58

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 (1) 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 (1). 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 SPParameter_1,Parameter_2,...	CR

- Command String – Formal syntax with command concatenation and addressing:

Start	Address	Body	Delimiter
#	Device_id@	Command_1Parameter1_1,Parameter1_2,...|Command_2Parameter2_1,Parameter2_2,...|Command_3Parameter3_1,Parameter3_2,...|...	CR

• Device Message Format:

Start	Address (optional)	Body	Delimiter
~	Device_id@	Message	CR LF

- Device Long Response – Echoing command:

Start	Address (optional)	Body	Delimiter
~	Device_id@	Command SP [Param1,Param2...] result	CR LF

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",0x0DCopy the EDID data from the default EDID source to the Input:"#CPEDID 2,0,0,0x1",0x0D
