Important note:
6.2.1 Line rate (Command LR)
This function can set the line rate longer than 1L. Accordingly, it is possible to set the camera scan
rate with the object running speed or to boost up the sensitivity by setting longer exposure time.
Adjusting range: 54.79 µs(1L) to 14.30 ms
Adjusting unit: 11.9 ns
