Scan timing
Non-scan code output
The trigger signal input delay time is used to control the time from the trigger signal ON to the start of a scan timing (exposure
start), as well as to prevent the timing signal from functioning incorrectly due to some mechanical or external noise. You may
change the delay time with the command or configuration software.
