8. Interfaces

The interface

RS485

is connected via a screened data line with twisted wires (Twisted-Pair). On each end

of the bus segment a termination of the bus lines needs to be connected. This is neccessary to ensure a
secure data transfer to the bus. For this a resistance (120 Ohm) is interposed between the lines Data B (+)
and Data A (–).
