5. Inputs and Outputs
5.1 Communication Setting
Baud rate: 9600 bps, Parity bit: None, Data bits: 8, Stop bit:1
5.2 Input data format
There is only one byte in each input data pack. Users could send different
commands to the sensor for different purpose, the functions of command are
shown in the following table.
Power On &
Trigger Measuring
5.3 Output data format
Digital output data is displayed by ASCII code, there is 7 bytes in every data frame.
The frame header is 0XFF, the next bytes meant measured distance numbers (unit:
mm). A: hundreds of thousands, B: tens of thousands, C: thousands, D: hundreds,
E: tens, F: ones.(Notice: If any byte in a data frame is not used, the sensor will
return 0X20 in that byte.)
The mapping table of HEX and number codes:
For example, if the measured distance data is 3456mm, then the sensor willreturn
data as" 3456"(HEX: FF 20 20 33 34 35 36).
Or the measured distance data is 123456mm, then the sensor will return data as
"123456"(HEX: FF 31 32 33 34 35 36).
If the sensor couldn’t get any available data( out of measurement range or
measured in blind zone), it will return “ - - - -”(HEX:FF 20 2D 2D 2D 2D 20) to
the computer.
