To connect the detector to other devices, use the two analog-out/event-in (I/O) connectors and
their mating connectors on the rear panel.
2.6.3.1 Generating an inject-start function
To generate the detector’s inject-start function at the start of an injection, connect cables as shown
in the following table and figure.
Tip:
The firmware defaults to Autozero on injection.

2998 PDA detector
2.6.3.2 Generating a stop-flow signal
The detector is fitted with a programmable switch output controlled by threshold or timed events.
To enable the generation of a stop flow, connect cables shown in the following table and figure.
Requirement:
To automatically stop the solvent flow within the system in the event of an error
condition or hardware failure, the stop-flow signal must be sent to the system’s pump.
