Section 4: Description of the Input
General information: Depending on the master, it is possible that the low byte (bit 0 - 7)
and the high byte (bit 8 - 15) might have to be swapped. The transmission mode
(big endian/little endian) always has to be adjusted such that the analogue values are
transmitted correctly. Only then can the binary data be swapped.
