Status request, meaning of the bytes
Byte Nr. meaning comment
1+ 2 HW/SW version
3 + 4 First active pixel Can not be changed by the user
5 + 6 Last active pixel Can not be changed by the user
7 + 8 Hi-Byte of threshold level 1
9 + 10 Low-Byte of threshold level 1
11 + 12 Hi-Byte of threshold level 2
13 + 14 Low-Byte of threshold level 2
15 + 16 Duration of exposure As long as this value is below max. exposure time the sensor is not
soiled
17 + 18 Type of measurement This two bytes represent the actual type of measurement
Bit 0: Sensor stays in programming mode
Bit 1: Sensor stays in SET-Mode
Bit 3: left edge
Bit 4: right edge
Bit 5: center position
Bit 6: width / distance edges
Bit 7: width / sum of objects
Example:
Sensor sends ASCII-Code 0x30 0x38, = hexadecimal number
0x08 or binary 0000’1000
left edge
19 + 20 Internal parameter Factory use only
21 + 22 Internal parameter Factory use only
23 + 24 Max. exposure value Factory set
If the value “duration of exposure” reach this limit, the alarm output
is set.
