Triggering
For area or line scan cameras, use the following information...
Configuration file directives
MODE_CNTL_NORM: 00
(default)
serial_init:
Camera-specific serial command(s) to initialize for freerun. Use as
needed (usually not needed because most cameras power on in freerun by default).
serial_exposure:
Camera-specific serial command to set the exposure time; for
example, use
"set"
for the Dalsa 1M60.
API subroutine
pdv_set_exposure(),
Camera-specific range and units.
Triggered by EDT Board (On-Demand)
In this mode, the camera sends a 1-millisecond trigger pulse over a camera control line, typically CC1, each time a
request for acquisition is made
–
such as when
pdv_start_images()
is called. Exposure time is controlled by the
camera, and typically is set via a camera-specific serial command.
For area or line scan cameras, use the following information...
Configuration file directives
MODE_CNTL_NORM: 10
method_camera_shutter_timing: AIA_SER
(default)
serial_init:
Camera-specific serial argument to enable triggering via CC1.
serial_exposure:
Camera-specific serial command to set the exposure time; for
example, use
"set"
for the Dalsa 1M60.
API subroutine
pdv_set_exposure(),
Camera-specific range and units.
Triggered by EDT Board (Fixed Period)
In this mode, the board sends a fixed periodic trigger signal over a camera control line, typically CC1, for each frame or
line of image data.
For area scan cameras, use the following information...
Configuration file directives
MODE_CNTL_NORM: 10
CL_CFG2_NORM:
The default is 00, which selects current channels counter; use 80 to
select other channels counter (i.e., if synchronized trigger output is desired).
method_frame_timing: FMRATE_ENABLE
frame_period:
Microsecond units (range 0
–
16777215).
photo_trig: 1
serial_init:
Camera-specific serial command to enable triggering via CC1.
API subroutine
pdv_set_frame_period(),
Microsecond units (range 0
–
16777215).
For line scan cameras, use the following information...
Configuration file directives
MODE_CNTL_NORM: 10
CL_CFG_NORM: 14
CL_CFG2_NORM:
The default is 00, which selects current channels counter; use 80 to
select other channels counter (i.e., if synchronized trigger output is desired).
xregwrite_16: 40
method_frame_timing: FMRATE_ENABLE
frame_period:
Microsecond units (range 0
–
16777215).
serial_init:
Camera-specific serial command to enable triggering via CC1.
API subroutine
pdv_set_frame_period(),
Microsecond units (range 0
–
16777215).
