Acquisition Control AW00118302000
84 Basler racer GigE
and will remain valid until enough lines have been acquired to constitute a complete frame.
The frame start trigger will then become invalid.
Line 1 - When the frame start trigger source is set to line 1, the user triggers frame start by
applying an external electrical signal (referred to as an ExFSTrig signal) to physical input line 1
on the camera.
Line 2 - When the frame start trigger source is set to line 2, the user triggers frame start by
applying an ExFSTrig signal to physical input line 2 on the camera.
Line 3 - When the frame start trigger source is set to line 3, the user triggers frame start by
applying an ExFSTrig signal to physical input line 3 on the camera.
Shaft Encoder Module Out - When the frame start trigger source is set to shaft encoder module
out, the output signal from the camera’s shaft encoder software module will trigger frame start.
If the Frame Start Trigger Source parameter is set to Line 1, Line 2, Line 3, or Shaft Encoder Module
Out, the user must also set the Frame Start Trigger Activation parameter. The available settings for
the Frame Start Trigger Activation parameter are:
Rising Edge - specifies that a rising edge of the source signal will make the frame start trigger
valid. The frame start trigger will remain valid until enough lines have been acquired to
constitute a complete frame and then will become invalid.
Falling Edge - specifies that a falling edge of the source signal will make the frame start trigger
valid. The frame start trigger will remain valid until enough lines have been acquired to
constitute a complete frame and then will become invalid.
Level High - specifies that a rising edge of the source signal will make the frame start trigger
valid. The frame start trigger will remain valid as long as the signal remains high. The frame
start trigger will become invalid when the signal becomes low.
Level Low - specifies that a falling edge of the source signal will make the frame start trigger
valid. The frame start trigger will remain valid as long as the signal remains low. The frame
start trigger will become invalid when the signal becomes high.
If the Frame Start Trigger Activation parameter is set to Level High or Level Low, the user must also
set the Partial Closing Frame parameter. The available settings for the Partial Closing Frame
parameter are:
True: When the frame start trigger signal transitions while a frame is being acquired frame
acquisition will stop and only the portion of the frame acquired so far will be transmitted.
False - When the frame start trigger signal transitions while a frame is being acquired the
complete frame will be acquired and transmitted.
By default, Input Line 3 is selected as the source signal for the Frame Start Trigger.
If the Frame Start Trigger Source parameter is set to Shaft Encoder Module Out,
the recommended setting for the Frame Start Trigger Activation parameter is
Rising Edge.
If the Frame Start Trigger Source parameter is set to Line 1, Line 2, or Line 3, the
electrical signal applied to the selected input line must be held high for at least 100
ns for the camera to detect a transition from low to high and must be held low for
at least 100 ns for the camera to detect a transition from high to low.
