40 Serial Interface: How to Control the Camera
Mode 4: Smart EXSYNC, External Frame Rate and Exposure Time
In this mode, EXSYNC sets both the frame period and the exposure time. The rising edge of EXSYNC
marks the beginning of the exposure and the falling edge initiates readout. There is a 100μs delay
between the trigger and the start of the exposure. The minimum delay between consecutive exposure
times is 150μs. The minimum pulse width (exposure time) is 40μs.
Note: The exposure and readout time can overlap. However, the camera will ignore the
falling edge of EXSYNC if the camera is still reading out the prior frame, and extends the
exposure time until the end of the previous readout.
