7.4. Exposure auto control (Commands: ASC, ASCS, ASCEA, ASCEI)
This turns the auto exposure function “ON” or “OFF” and provides settings for various
parameters.
ASC=0 (OFF), ASC=1 (ON)
ASCS: ASC tracking speed setting. Range is from 1 to 16 (Default is 8).
ASCEA: Maximum exposure time in the ASC mode. Range is from 10 to 1048575 (
μ
s).
ASCEI: Minimum exposure time in the ASC mode. Range is from 10 to 1048575 (
μ
s).
This function is available for continuous operation and pre-dump ON.
7.5. Normal continuous operation
This is used for applications which do not require triggering. In this mode, the video signal
for the auto-iris lens is available.
For the video timing, refer to the chapters 6.2, 6.3 and 6.4.
The frame rate of full pixels readout is 68fps for 2 tap output and 34fps for 1 tap output.

Note: The AM-200CL and AB-200CL are designed to give priority to the frame rate rather
than the exposure time. If the exposure time is set at a longer time than
15.56ms (1 frame time), the frame rate must be set at a longer time than the
exposure time.
