RS-485 is the most versatile communication standard. The RS-485 standard defines the electrical characteristics of drivers and receivers for use in digital systems. The standard is published by the Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA). RS-485 signals are used in a wide range of computer and automation systems and are used in programmable logic controllers and on factory floors. Since it is differential, it resists electromagnetic interference from motors and welding equipment. It may be used to control video surveillance systems or to interconnect security control panels and devices such as access control card readers. It does not specify or recommend any communications protocol. In the next table the electrical characteristics of the standard are defined.
The RS-485 module for Arduino and Raspberry allows users to perform industrial and domotic applications. The RS-485 is the most versatile communication standard in the standard. This a standard defining the electrical characteristics of drivers and receivers for use in digital systems. It does not specify or recommend any communications protocol. In the next table the electrical characteristics of the standart are defined.
