Luxtron FOT Lab Kit - Parameter Commands

User Interface Commands
4-2 FOT Lab Kit User’s Manual
Parameter Commands (Two-Letter)
The Parameter Commands are used to adjust user-selectable
parameters and to query the instrument to report a current
parameter setting.
The Parameter Command code consist of the Escape character
(1Bh) followed by two ASCII characters defining the command with
optional arguments for retrieving information or setting system
parameters. Commands are not case sensitive.
White space (spaces/tabs) is allowed but is ignored except where it
is necessary for separation of arguments.
All commands must be terminated by a carriage-return character CR
(0Dh) optionally followed by a line feed character LF (0Ah).
These parameter commands are used in either of two ways:
information requests or parameter modification.
Information
Requests
This command format consists of the Escape character followed by a
two-letter command followed by a question mark and carriage
return/line feed.
Example Query: <Esc>AA ? <CRLF>
Informational output data packets consist of echoing the command
code in upper case characters followed by an equal sign ( = )
followed by the requested information. The Escape character is not
echoed.
White space is consistently applied with exactly one (1) space
character between each pair of arguments.
