10.4.23 SetExposureLo
Sets the exposure time (low 16 bits) of the camera. This command, along with SetExposureHi
defines the exposure time as a 32 bit value. The actual exposure time depends on the selected
frame rate. The formulas for calculating the exposure time are;
30fps; Exposure Time(seconds)= (32 bit trigger value) * 250ns
60fps; Exposure Time (seconds)= (32 bit trigger value) * 125ns
Minimum = TBDms for 30fps frame rate
Minimum = TBDms for 60fps frame rate
Maximum = TBDms for 30fps frame rate
Maximum = TBDms for 60fps frame rate
Note: When changing exposure time, both the Lo & Hi must be changed, and the Lo command
MUST precede the Hi command.
