5.3.4.3 Contacts & Inputs Screen
The Contacts & Inputs screen is used to activate the individual outputs and view the state of
the inputs related to the Digital I/O terminals on the rear panel of the detector.

The following parameters and functions are available on the screen:
Parameter Description
Contact 1 & 2 For use with compatible chromatography data systems to interact with
external devices.
Pump Dedicated output for connection to external pump. During an alarm
condition, a signal will be sent to shut down the pump and stop liquid
flow to the detector. Requires a compatible LC pump with dedicated
outputs.
Start For use with compatible chromatography data systems to initiate data
collection. For more information, refer to the user documentation of the
chromatography software.
Gas Off Dedicated input to shut down the gas flow to the detector. Requires a
compatible LC system and chromatography software to program this
parameter.
Autozero Adjusts the output signal to zero at the current range in use. This function
can be turned off.
SSV Position For external control of the stream-switching valve.
For further information about the digital inputs and outputs, see section 11.1 (→ page 129).
