Appendix D
characters before or after are ignored, as well as white space (spaces and tabs) before or after
the parentheses. This string would work equally as well, for example:
This is ignored ( Outputs (BW 10 )) and so is this
The LI-7500 does not try parsing a command string until a line feed is received. Since "extra"
characters are ignored, commands can be terminated with carriage return and line feeds
equally as well.
Another example of a command string is
(Outputs(RS232(Freq 10)(Pres TRUE))(BW 5))
In this case, we are setting the RS-232 output frequency to 10Hz, requesting that Pressure be
included in the output records, and that the bandwidth be 5 Hz. Notice the 2 parentheses at the
end of
(Pres TRUE))
. This is because
(Pres..)
and
(Freq..)
are
(RS232..)
commands,
while
(BW..)
is not.
(BW..)
and
(RS232..)
are both
(Outputs..)
commands, however, and
the “extra” paranthesis at the end of
(BW 5))
signals the end of the
(Outputs..)
command.
An illegal command string would be
(BW 5)
