Select the activation mode for the selected Input Line trigger
source. This is applicable only for external line input lines.
The trigger is considered valid on the rising edge of the line
source signal (after any processing by the line inverter
module).
The trigger is considered valid on the falling edge.
The trigger is considered valid on any edge.
The trigger is considered valid as long as the level of the
source signal is high.
The trigger is considered valid as long as the level of the
source signal is low.
Specifies if a trigger overlap is permitted with the Active
Frame or Active Line signal. This defines if a new valid trigger
will be accepted (or latched) for a new frame or line.
No trigger overlap is permitted. (Frame Trigger).
Trigger is accepted immediately after the exposure period
(readout). (Line Trigger)
Overlapped exposures must not end before readout of the
previous exposure.
Trigger is accepted (latched) at any time during the capture
of the previous line. (Line Trigger)
Only frame triggers can be delayed. Specifies the delay to
apply after receiving the trigger and before activating
triggerEvent. The delay can be set in microseconds or in line
trigger signals. The delayer can buffer and apply the
specified delay to a maximum of 128 frame trigger pulses
simultaneously. Any additional triggers will be lost if the
trigger delayer buffer is full.
Sets the event that increments the trigger delay counter.
The delay counter increments on each microsecond tick of
the device internal Clock.
The delay counter increments on each pulse received by the
line trigger module. The delay counter increments even if the
pulse is rejected by the line trigger module.
Current line frequency measured by the camera.
Specifies the conditions for the Rotary Encoder interface to
generate a valid Encoder output signal.
On the camera, the "position" behaviour exists, but the
number of counts is small (7-bits / 128 counts). The encoder
can reverse for 256 ticks and then go forward and behave as
expected for "position" style behaviour. If the user exceeds
256 ticks, the count will max out, but will not reset. When
the user starts going forward again, 256 lines will be dropped
/ ignored and then resume output.
The triggers are generated for all motion increments in either
direction.
