Key functions6.3.1 Line rate (Command LR)This function can set the line rate longer than 1L. Accordingly, it is possible to match thecamera scan rate with the object running speed, or to boost up the sensitivity by setting alonger exposure time. Adjusting range: 32.9125μs(1L) to 16.844ms Adjusting unit: 12.5ns Operation mode: TG=0 Internal trigger Applicable mode: No-shutter/Internal, Shutter select/InternalThe line rate can be automatically configured (one-push auto line set) (Command:AR).This function will calculate and set the line rate of the camera based on the AutomaticLine Rate Reference Level (Command :AL) and the scene illumination.6.3.2 Electronic shutter (Exposure) (Command PER, PEG, PEB)This function sets the exposure time regardless of line rate setting. The exposure timecan be set for red, blue, and green, respectively.Command PER= 2064 to 1056720PEG= 2064 to 1056720PEB= 2064 to 1056720 Adjusting range: 25.8μs (2064clk) to 13.209ms (1056720clk)(RGB individually) Adjusting unit: 12.5 ns (1clock) (RGB individually) Operation mode: Shutter select/internal trigger and shutterselect/external triggerNote:Exposure time can be set as mentioned before. However, if the line rate is shorterthan the exposure time, the accumulation time is determined by the line rate.This should be noted especially in external trigger mode.
