5.1 Communication settings
Baud rate: 9600 bps , Parity bit: None , Data bits: 8 , Stop bit: 1
5.2 Input frame format
There is only one byte in every input frame. Users could send different commands
to the sensor for different purpose, the functions of command are shown in the
following table.

5.3 Output frame 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.)

For example, if the measured distance data is 3456mm, then the sensor will
return 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).
