Programmed Integration/SMA Trigger
For external SMA controlled triggering with a programmed integration time, a TTL rising
edge on the TRIGGER IN signal triggers the camera to acquire one frame of data.
Integration begins within 200ns after the rising edge and stops when the programmed
integration time has completed. After that single frame acquisition, the camera transfers
the image to the memory region of the CCD and then outputs the just acquired frame.
The camera is "re-armed" when the transfer of the image into the memory region off the
CCD is completed. No additional rising edges, or triggers, should be allowed during the image
acquisition or image to memory transfer.
When the camera is in External Trigger Mode, the MODE LED will be illuminated on the
camera back to indicate the camera is expecting a signal on the SMA connector or bit [0]
of the Control Register.
Because TRIGGER IN is internally OR'ed with bit[0] of the Control Register, care must be
taken to ensure the serial bit [0] of Control Register 1 is not changed from logic 0 to 1
while triggering with the SMA Trigger input.
Programmed Integration/Serial Trigger
For external serial controlled triggering with a programmed integration time, a TTL rising
edge on bit [0] of the Control Register triggers the camera to acquire one frame of data.
Integration begins within 200ns after the rising edge and stops when the programmed
integration time has completed. After that single frame acquisition, the camera transfers
the image to the memory region of the CCD and then outputs the just acquired frame.
The camera is "re-armed" when the transfer of the image into the memory region off the
CCD is completed. No additional rising edges, or triggers, should be allowed during the image
acquisition or image to memory transfer.
When the camera is in External Trigger Mode, the MODE LED will be illuminated on the
camera back to indicate the camera is expecting a signal on the SMA connector or bit [0]
of the Control Register.
Because the serial trigger bit signal is internally OR'ed with the SMA TRIGGER IN, care
must be taken to ensure the SMA TRIGGER IN signal is not changed from logic 0 to 1
while triggering with bit[0] of the Control Register.
External Integration/SMA Trigger
When in External Integration/SMA mode, a TTL rising edge on the TRIGGER IN signal
triggers the camera to acquire one frame of data. Integration begins within 200 ns after
the rising edge and stops within 400 ns after the falling edge. After that single frame
acquisition, the camera transfers the image to the memory region of the CCD and then
outputs the just acquired frame. The camera is "re-armed" when the image to memory
transfer is completed. No additional rising edges, or triggers, should be allowed during the
image acquisition or image to memory transfer. In this mode TRIGGER IN necessarily
controls both integration and frame rate.
