SL-280 – Protocol 3000
29
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. The maximum string length is 64 characters.
• Message starting character:
 # – For host command/query
 ~ – For device response
• 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 para
meters 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.
