Remarks: Because the environment light intensity is too large, the ambient temperature is too high or too low, the reflector is too weak or too strong, or the target of a rough surface, different measurement objectives and measurement environment may cause some error of the measurement range or measurement results.

• ADDR Device Address

•Postion is 1, count from the top , when item is 0, count from the end (FA 04 08 01 F9),The default setting is from end

•CS check byte, it sums all the bytes in front,Returns the reverse, plus 1, in the data returned by single measurements and successive measurements, in which the quotes are part of the data,Format is ASCII sample:123.456 m display 31 32 33 2E 34 35 36 ADDR Default value 80(128)
