Manual optoNCDT 1402 - Micro-Epsilon

OperationRecommendations:--Use a high measurement rate for light colored and matt objects to be measured.--Use a low measurement rate for dark or shiny objects to be measured (e.g. surfaces covered in blacklacquer), for better measurement results.Output Maximum output rate The sensor continues to measure internally butCurrent Measurement rateholds back the output until the last measurementvalue has been issued in full. The next measurementvalue is the last valid value, with other valuesOutput rate £ Measurement rate;RS422Dependent on the transmission ratebetween being lost.(baud rate) and data format (ASCIIcode).Fig. 16 Output rates for the output typesCalculation of the output rate using the RS422 serial interface:Output rate = Measuring rate / nAbbreviations used:n = Partial factorint = Integral part of ( )b = Byte/measurement value (binary format b=2,ASCII b=6)MR = Measurement rate [Hz]n = int (b * 10 * MR / BR) + 1BR = Baud rate [Baud]Example:Measurement rate = 750 Hz, ASCII-Format (b=6), Baud rate = 115200 Baud--> n = int (0.39) + 1 = 1--> Output rate = 750 Hz / 1 = 750 Hz.optoNCDT 1402Page 34
