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)
#
Device_id@
•
Simple Command – Command string with only one command without
addressing:
Start
#
VP-733 – Protocol 3000
CR – Carriage return for host messages (ASCII 13)
CR LF – Carriage return for device messages (ASCII 13) and line-feed
(ASCII 10)
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.
