9.1 TTL I/O Operational Controls
Operational Trigger (Pin 2): The input signal on this pin controls the operation of the Pumping Program. Its
functionality is user configurable. Use the ‘TRG' command to configure the default settings for this input pin
(See Section 6.5, TTL I/O Operational Trigger Default Configuration).
Each option defines when the Operational Trigger input is activated. When activated, the trigger emulates a
‘Start/Stop’ key.
Foot Switch: Operates like a ‘Start/Stop’ key, whereby each falling edge (contact to ground) either starts
or stops/pauses the Pumping Program.
Foot Switch Hold: Falling edge starts the Pumping Program and the rising edge stops the Pumping Program.
With a foot switch, the Pumping Program will run while the foot switch was held down.
