5.5.5. Reset counters
This command will reset the counters for both presence detection and bidirectional
people traffic detection modes.
Once the sensor receives the reset command, the sensor outputs the following frames
that contain this additional information:
5.5.5.1.
BPTD “Bidirectional People Traffic Mode”
“PC”
2 bytes Counter
4 bytes Counter IN
2 bytes Counter OUT
2 bytes CRC
1 byte
Where: “PC”: frame header
Counter = Counter IN - Counter OUT ​= 0
Counter IN: number of people passing by from Left to Right ​= 0
Counter OUT: number of people passing by from Right to Left ​= 0
​CRC Byte
5.5.5.2.
PD Presence Detection Mode
“PP”
2 bytes Presence Detection counter
4 bytes CRC
1 byte
Where: “PP”: frame header
Presence Detection meter countingpeople detected as present ​= 0
CRC Byte
5.5.6. Parameters Command
5.5.6.1. Binary Frame
This command provides users with all parameter values in binary form and returns the
following frames:
“BP” BPTD ​
max range thresholds (millimeters)
