RS485 Termination Both ends of the RS485 communication line is terminated by a resistor, often the resistor is chosen to be 100 ohms. The reason for this resistor is because there is a conflict between fast data rates and the slow speed (by comparison) of the electricity in the wires (somewhat less than a foot in a Nano-second). Many signal integrity and communication issues with RS-485 networks stem from terminations, either from a lack of termination or improper termination. In this installment of the RS-485 basics series, I’ll talk about when you can get away without terminating your RS-485 network, and if you need termination, how to use standard (parallel For RS-485 (2-wire, point-to-point or multi-drop), terminate the wire pair at each end of the network. The diagram in Serial Network Topologies shows the correct location of the termination.

RS485 data transmission lines should always be terminated with a resistor or a combined resistor with capacitor and stubs should be as short as possible to avoid signal reflections on the line.

Mellom slaver blir imidlertid T+/T- og R+/R- "Twisted pair". Terminering (ca 120 ohm) legges mellom de to parene som er tvunnet. De fleste enheter har nå slik terminering som dip switcher. For 2-leder kobles T+/R+ og T-/R- sammen. Siste enhet termineres. Engelskspråklig d ebatt forum ang RS422 og RS485 finner dere her.

Example of RS-485 Communication Cable Beyond the network cabling, it is mandatory that the layout of printed-circuit boards and the connector pin assignments of RS-485 equipment maintain the electrical characteristics of the network by keeping both signal lines close and equidistant to another.
