8 The RS-232/Ethernet (UDP) Communication

Protocol

The VP-440 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 Section 8.1

• Kramer Protocol 3000 commands (see Section 8.2)

• Kramer Protocol 3000 detailed commands (See Section 8.3)

8.1 Kramer Protocol 3000 Syntax

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

8.1.1 Host Message Format

Simple Command

8.1.2 Device Message Format

Device Long Response

Echoing command:

CR LF

~

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

8.1.3 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

Command SP [Param1 ,Param2 …] result CR LF

38 VP-440 - The RS-232/Ethernet (UDP) Communication Protocol

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; carri age return (ASCI I 13)
CRLF – For mac hi ne messages; carriage return (A SCII 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.

8.1.4 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.

8.1.5 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.

8.1.6 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.
