Setting of the terminal resistors at the start and end of the bus line is not necessary in
most cases due to internal EMC measures. Depending on local circumstances, the data
transmission may worsen in individual cases.
The appropriate pin assignment of the controller can be found in the manufacturer's
interface description.
Under Os Windows 7 or 10 is only a point to point connection possible.
