Serial Interface: How to Control the Camera 37
In non-concurrent mode, a low-to-high transition in the EXSYNC signal starts the integration time, and a
high-to-low transition in the EXSYNC signal starts the readout of image data. This is the same as in
concurrent mode. The difference between these two modes is that you do not perform your next low-to-
high transition of EXSYNC until readout has completed. The Waiting period can be reduced to 0 seconds
by starting the low-to-high transition immediately after readout is complete. The readout time is a fixed
amount of time that is dependant upon the mode of operation of the camera, but is typically around
10.0ms.
