Trigger Input Line Activation
TriggerActivation
Select the activation mode for the selected Input
Line trigger source. This is applicable only for
external line inputs.
Beginner
Rising Edge
RisingEdge The trigger is considered valid on the rising edge of
the line source signal (after any processing by the
line inverter module).
Line Selector
LineSelector
Selects the physical line (or pin) of the external
device connector to configure.
Beginner
Line 1
Line1 Index of the physical line to use. Always configured
as input signal. On the Calibir 640 GigE, Line0
corresponds to Pin 4 of the I/O connector, with the
common ground on Pin 7.

External Trigger Input Timing
Calibir 640 GigE camera sensors support an external trigger input for frame acquistion. The trigger
is asserted on the rising edge of the voltage transition. External signals are isolated by an opto-
coupler input with a time programmable debounce circuit. The Input Line Debouncing feature
specifies the minimum length of time the trigger must be held high to be considered a valid trigger
(triggers shorter than the minimum input debounce time are ignored). When a valid trigger is
received, the next available frame is acquired (any subsequent triggers received before the start of
the frame are ignored).
