TTL Input Functions
The four TTL inputs can be connected to devices capable of providing
TTL output signals. Signals from the connected devices can control up to
four of the functions listed in the table below. Use the
the

Description
Returns the analog (recorder) output to a predetermined baseline
and zeros the display.
Controls the detector method clock. A signal from the
controlling device can turn the method clock on (Run) and off
(Hold/Reset). Hold/Reset resets the method clock to zero and
executes
conditions.
INIT
Turns the suppressor (Dionex SRS or AES) current off and on.
Increases the method number by one. Each additional signal
increases the method number by one more.
When the method clock is zero (or
number executes the
the method clock is greater than zero, increasing the method
number begins running the new method at the current elapsed
method clock time. This has the same result as selecting a new
method number when the detector is in Local mode.
Decreases the method number by one. The operation is as
described under TTL input 3 above, except that the method
number decreases.
Sends a 10% positive event mark to the analog (recorder) output.
Sets the analog output scale factor between 0.01 and 3000 S.
Amperometry mode only: Turns the cell off and on.
