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.
