6-4 Command Format
For example, the system command string
"
#
00W12
",
followed by a carriage return, will cause the PIM-3
addressed as "
00
" to process the "
W1
" command with an
information input of "
2
". The
W1
system command
changes the baud rate to the number represented by "
2
",
which is 2400 baud.
An example of an amplifier command string is
"
#03F1
". This command, followed by a carriage return,
causes the PIM-3 addressed as "
03
" to process the "
F1
"
command. The "
F1
" command activates the tare func-
tion, and thus this command string activates the tare func-
tion for the amplifier.
The first character of each two-character command
code signifies if that command is a function command
("F"), a read operating parameter command ("R"), or a
write operating parameter command ("W").
Read and
write commands can be used to configure the operation of
the instrument.
Function commands are used to gather
data from the instrument or to cause it to perform an oper-
ation.
All characters received before the pound sign are
ignored. Therefore, one or more PIM-3 instruments can
share a single communications link with other "foreign
instruments" (within the physical limits of the RS-232 or
RS-422/RS-485 interface, of course) as long as the host
or the "foreign instruments" do not use the "#" character.
When the "#" character is sent to an PIM-3, the instru-
ment enters its receive mode and will attempt to parse out
the rest of the characters before the carriage return as a
possible message.
