Programmed Integration/SMA Trigger
For external SMA controlled triggering with a programmed integration time, a TTL rising
edge on TRIGGER IN connector triggers the camera to acquire one frame of data.
Integration begins within 175 ns after the rising edge and stops when the programmed
integration time has completed. After that single frame acquisition, the camera outputs
the just acquired frame and "re-arms", thus waiting for a new External Trigger signal to
trigger a new frame acquisition. The camera is "armed" when the read out of the
acquired frame is completed. No additional rising edges, or triggers, should be allowed during
the image acquisition or frame read out.
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 TRIGGER IN connector or
Serial Trigger bit [0] of the Control Register.
Because this signal is internally OR'ed with the Serial Trigger bit [0] of the Control
Register, care must be taken to ensure the bit [0] of the Control Register is not changed
from logic 0 to 1 while triggering with the TRIGGER IN connector.
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 175 ns after the rising edge and stops when the programmed
integration time has completed. After that single frame acquisition, the camera outputs
the just acquired frame and "re-arms", thus waiting for a new External Trigger signal to
trigger a new frame acquisition. The camera is "armed" when the read out of the
acquired frame is completed. No additional rising edges, or triggers, should be allowed during
the image acquisition or frame read out.
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 serial bit [0] of the Control
Register, or the TRIGGER IN connector.
Because this signal is internally OR'ed with the TRIGGER IN input, care must be taken to
ensure the 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 175 ns after
the rising edge and stops within 200 ns after the falling edge. After that single frame
acquisition, the camera outputs the just acquired frame and "re-arms", thus waiting for a
