    Appendix 1. RS-422 / RS-485 EIA-485 [TIA-485] Balanced (differential) interface; defines the Physical layer, signaling protocol is not defined. EIA-485 specifies bidirectional, half-duplex data transmission. Up to 32 transmitters and 32 receivers may be interconnected in any combination, including one driver and multiple receivers (multi-drop), or one receiver and multiple drivers.

  • Page 58: A1.1 Rs-422 Point-To-Point Circuit

    A1.1 RS-422 Point-to-Point Circuit This is the simplest configuration, just one driver and one receiver. If termination is used, it is only required at the receiver end. Most RS-422 cables used to connect telecom or data-com equipment are point to point links. A1.2 RS-422 Multi-drop Network In this topology there is only one driver sending to one or more receivers.

  • Page 59: A1.4 Rs-485 Half-Duplex 2-Wire Network

    A1.4 RS-485 Half-duplex 2-wire Network This is the typical RS-485 topology. It takes advantage of RS-485 capability to support multiple drivers on a bus. RS-422 devices should not be used in this configuration. This topology enables bidirectional communication from many nodes over long distances at low to medium data rates, all on a single pair of wires (2-wire).
