8.2.3.2 Frame Start Trigger Mode = On
When the Frame Start Trigger Mode parameter is set to on, you must select a source signal for the
frame start trigger. The Frame Start Trigger Source parameter specifies the source of the signal.
The available selections for the Frame Start Trigger Source parameter are:
 Software - When the frame start trigger source is set to software, the user triggers frame start
by issuing a TriggerSoftware command to the camera from the host PC. Each time a
TriggerSoftware command is received by the camera, the frame start trigger will become valid
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 ExFrameStTrig 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 ExFrameStTrig 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 ExFrameStTrig 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.
