Bias
RS-485 networks are executed in a bus topology and are terminated at both ends with a ter-
mination resistor between the data lines. Furthermore, the bus lines are brought once to a
defined quiescent level with bias resistors. The Inline controller has resistor networks for ter-
The micro SD card is not supplied as standard with the Inline controller.
