Continuous distance measurement

Due to eye safety restrictions, the host system must ensure to request measurement commands with a
maximum frequency of 2 Hz.
The LRF Module does not ensure that the maximum measurement frequency of 2 Hz is maintained.
Keep in mind that eye safety of the host system is in the responsibility of the system integrator.
6.2.2.1 Checksum Calculation
The checksum is calculated by adding the binary representations of the first eight ASCII characters of the
data string. The least significant byte of the result in hexadecimal representation is converted into two
ASCII characters.
Raw Data example: v0005950D9, where the checksum is D9
