optoNCDT 1402

Set Measurement Rate

8.3.13

Name:

SET_SCANRATE

Beschreibung: Sets the measurement rate [Hz].
Parameter:

X = 0 --> 1500

- X = 3 --> 375

X = 1 --> 1000

- X = 4 --> 50

X = 2 --> 750

Procedure: The sensor replies and then re-boots. The string of the boot message contains “CI140x“, “CR“
“LF“ and the answer of “GET_INFO“.
