2.5 DIP Switch Settings (Modbus function will be available in 2020-5-30)
The rotating coded switch S3(0-F) on the main control board of hydraulic module is used for setting the Modbus
address. By defaulting the units have this coded switch positioned=0, but this corresponds to the Modbus address 16,
while the others positions correspond the number, e.g. pos=2 is address 2, pos=5 is address 5.
