9.2 Data Types
9.2.1
Type 0x16 – Distance Data
Direction: LPR
®
-1DHP-200 Unit → User
The data type 0x16 is the standard output data type. It contains measurement data, system
status information and settings. The default protocol frame length is 47 bytes.
Table 9.1
shows the structure of a 0x16 data packet.
The standard customer protocol length of the LPR
®
-1DHP(-R) sensor
(predecessor) was 50 bytes which has to be taken into account if a
LPR
®
-1DHP-200 is used to replace it.
The data packets are output with the internal update rate or the chosen update rate.
The internal measurement rate depends on the used radar mode, FFT
size and averaging setting. The output rate of the interface equals the
internal measurement rate if no custom output interval is set.
