Serial DataSystem Remote Start Operation
TheSRIserial
port data
systemoffers a remote starting capability as a standard feature.
This
permits
the user
to
start the
data
system (and SRI gas chromatograph,
if
attached)
by
means of a
switch closure, such as a
footswitch.
In
some applications, such aswhen adifferent brand of gas
chromatograph is being used with the serial data system. the chromatograph offers a remote start
signal
output (or switch closure output)
that
permits
starting anintegrator or other device when the
START button is pressed on the chromatograph's on-board control panel. Typically, this signal can
be
used
to
start the serial data system.
