To trigger from a PNP (pull-up) photo-detector or PLC output, connect TRIG+ to the output
of the detector and connect TRIG to 0V. When the output turns ON, it pulls TRIG+ up to the
supplied voltage, energizing the In-Sight camera’s trigger (Figure 3-3).
Figure 3-3: Acquisition Trigger Input (PNP Source)
To trigger from a differential input source, connect the negative input to TRIG- and the posi-
tive input to TRIG+. When a differential voltage exists, the In-Sight camera trigger is ener-
gized (Figure 3-4).
Figure 3-4: Acquisition Trigger Input (Differential Source)
An LED indicator is provided for the acquisition trigger and illuminates when an approximate
potential of >2V is supplied across the TRIG+ and TRIG terminals.
NOTE
Even if the TRIG LED indicator illuminates, this does not guarantee that the logical
threshold has been crossed. It only means that the TRIG+ and TRIG terminals are properly
connected to the trigger source.
