Data transmission lines should always be terminated and stubs should be as short as possible to avoid signal reflections on the line. Proper termination requires the matching of the terminating resistors, R. T, to the characteristic impedance, Z0, of the transmission cable.

WebTermination resistor prevents signal rebound, like waves hitting a wall. The characteristic impedance of twisted pair cables is not a magic number. Instead, it is derived from physical characteristics of the cable itself. In RS485, the twisted pair cable used is defined to have a characteristic impedance of 120 Ohm. WebStubs: RS-485recommends keeping the stubs as short as practical. A stub is the distance from the device to the bus, or the termination resistor (in the case at the ends of the bus), see Figure 9. The maximum length is not defined by the standard, but longer stubs will have a negative impact on signal quality.
