Byte Swap To support different microprocessors that store data in different formats, the HydroAct 4
can alter the data it sends and receives to match the format expected by the sensor. The byte
swap option allows the order of bytes in the 16-bit registers to be reversed.
Word Swap When two 16-bit registers are combined for larger data types, e.g., floating-point number
representations, this option reverses the order of the two 16-bit words to match the format
expected by the sensor.
