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 (–).
