Modern applications involving RS-485 often have data rates several times 10Mbps, and require higher speeds over longer distances. New RS-485 transceivers and cables are pushing the limit of RS-485 far beyond its original definitions.

What is RS-485? RS-485 (currently known as EIA/TIA-485) is a standard interface of the physical layer of communication, a signal transmission method, the 1st level of the OSI (Open System Interconnection) model. RS-485 has been created in order to expand the physical capabilities of RS-232 interface.

Figure 3-1. Multipoint RS-485 bus To set practical and measurable limits for RS-485 output drivers, the Telecommunications Industry Association (TIA)/Electronic Industries Alliance (EIA)-485 standard created a hypothetical "unit load," and then limited the maximum number of unit loads that can be presented to any driver on an RS-485 bus to 32.

White Paper—RS-485 Transceiver Tutorial Page 3 of 9 Basic RS-485 Transceivers Short, simple, low-node-count networks can often use low-cost RS-485 transceivers. Short networks won''t pick up much common mode voltage (CMV), so they don''t need more than the RS-485 standard CMR, nor should they need OVP.
1. RS485 Transceiver: The RS485 transceiver is the key component that interfaces between a serial communication device and the RS485 bus. It converts the logic level signals into differential signals, which are then transmitted over the RS485 bus.

RS-485, also known as TIA-485(-A) or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced, and multipoint systems are supported. The standard is jointly published by the Telecommunications Industry Association and Electronic Industries Alliance (TIA/EIA). Digital communications networks implementing the standard can be used effectively o…
The RS-485, which specifies bi-directional and half-duplex data transmission, is the only EIA/TIA standard that allows multiple receivers and drivers in "bus" configurations. Conversely RS-422 EIA/TIA standard specifies a single, unidirectional driver with multiple receivers. Therefore RS-485 parts are backward compatible and interchangeable ...

Abschlusswiderstände sollten Sie an jedem Ende einer RS …
As RS-485 meets all the RS-422 specifications (Table 3), RS-485 drivers can be used in RS-422 applications. The opposite, however, is not true. The common-mode output range for RS-485 drivers is -7V to +12V, whereas the common-mode range for RS-422 drivers is only ±3V. The minimum receiver-input resistance is 4kΩ for RS-422 drivers and 12kΩ ...
