VP-444 – RS-232/Ethernet (UDP) Communication Protocol

RS-232/Ethernet (UDP) Communication Protocol

The VP-444 can be operated using serial commands from a PC, remote controller, or touch screen. The unit communicates using the default Kramer Protocol 3000.

• Kramer Protocol 3000 syntax (see Kramer Protocol 3000 Syntax on page 34)

• Kramer Protocol 3000 commands (see Kramer Protocol 3000 – Command List

on page 36)

• Kramer Protocol 3000 detailed commands (See Kramer Protocol 3000 – Detailed

Commands on page 37)

Kramer Protocol 3000 Syntax

Protocol 3000 communicates at a data rate of 9,600 baud, no parity, 8 data bits and 1 stop bit.

CR = Carriage return (ASCII 13 = 0x0D); LF = Line feed (ASCII 10 = 0x0A); SP = Space (ASCII 32 = 0x20)

Command Terms

Command

A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-'). Command and parameters must be separated by at least one space.

Parameters

A sequence of alphameric 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. Note: A string can contain more than one command. Commands are separated by a pipe ( '|' )

character.

Message starting character

'#' – For host command/query '~' – For machine response

Device address (Optional, for K-NET)

K-NET Device ID followed by '@'

Query sign

'?' follows some commands to define a query request.

Message closing character

CR – For host messages; carriage return (ASCII 13) CRLF – For machine messages; carriage return (ASCII 13) + line-feed (ASCII 10)

Command chain separator character

When a message string contains more than one command, a pipe ( '|' ) character separates each command.

Spaces between parameters or command terms are ignored.

Entering Commands

You can directly enter all commands using a terminal with ASCII communications software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial or Ethernet port on the Kramer device. To enter CR press the Enter key. (LF is also sent but is ignored by command parser).

For commands sent from some non-Kramer controllers like Crestron, some characters require special coding (such as, /X##). Refer to the controller manual.

Page 38

Kramer Electronics Ltd.

VP-444 – RS-232/Ethernet (UDP) Communication Protocol

Command Forms

Some commands have short name syntax in addition to long name syntax to allow faster typing. The response is always in long syntax.

Command Chaining

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 once, at the beginning of the string and at the end.

Commands in the string do not execute until the closing character is entered. A separate response is sent for every command in the chain. torture

Maximum String Length

64 characters
