Figure 24: External Trigger Input Validation & Delay
Let t(et) = time of external trigger in µs
t(oc) = time opto-coupler takes to change state (time varies dependent on
input voltage)
t(d) = user set debounce duration from 1 to 255µs
t(vt) = time of validated trigger in µs
Table 29: External Trigger Timing Specifications
Note: Teledyne DALSA recommends using the fastest transition to minimize the time it takes
for the opto-coupler to change state.
If the duration of the external trigger is > t(oc) + t(d), then a valid acquisition trigger is detected.
It is possible to emulate an external trigger using the software trigger which is generated by a
function call from an application.
