4-11-2 RS-232 COMMAND PROCEDURE AND DATA STRUCTURE
All FM/AM-1200S/A functional commands and data information are trans-
ferred over the RS-232 as uppercase ASCII alphanumeric character strings
designed to replace the front panel controls.
All input commands sent to the FM/AM-1200S/A are placed in an internal
queue that will accommodate up to 128 bytes of data.
Command strings
may be packed together, but the individual commands must be separated by
a colon":" delimiter.
The colon":" may or may not cause the command
to be executed immediately, depending upon the type of external
controller being used.
The following ASCII Characters will always ter-
minate the command or series of commands:
ASCII Carriage Return (OD) - CR
ASCII Line Feed
(OA) - LF
Maximum command string length including spaces and delimiters is 128
characters.
If the command string exceeds 128 characters, everything up
to the most recent delimiter will be accepted and the rest ignored.
All
spaces will be ignored except when using the"!" command.
Returned data to the external controller will not be packed together in
a string.
Instead, each set of data returned will be on an individual
line and sent out in the order in which its command was sent.
That is,
the first "get" instruction sent in a command string will cause the
returned data to be on the first 1 ine of the output; the second ''get''
instruction will cause the returned data to be on the second line of the
output, and so on.
Data inputs that are out of specific range will generally default to the
minimum values or initial condition values.
