DIP switch selector

DIP switches are used to configure the host settings.
The first four DIP switches for address selection, define the RS-485 address of the AMC2 in an
RS-485 bus system.
Switch 5 selects one of the two different protocols, SDEB and BPA (according to DIN6619).
Switch 6 sets the connection to the host system to either RS-485 or the Project-specific
interface (PI).
