The RS-485 communications standard was introduced in 1983 by the Electronic Industries Alliance (EIA) as a two-wire, half-duplex, multi-drop alternative to the point-to-point RS-232 interface. (Note: RS-485 can also be wired using 4-wires to enable full-duplex communication). RS-485 uses...

RS-232, RS-422, and RS-485 have a long history in industrial automation. One of Moxa's most experienced engineers discusses the state of these legacy communication standards and how they are integrated in today's industrial communication equipment....

At a new international airport terminal, the equipment that monitored different aspects of airport operation needed to be connected to a control room over different media interfaces including Ethernet, RS-232, RS-422, and RS-485. An industrial communication solution was necessary to incorporate...

For many years, serial interfaces such as current loop, RS-232, and RS-485 have been the preferred methods for industrial communications. Ethernet offers high reliability with the proven ability to adapt to changing environments, especially new types of media (coaxial cable and wireless...

The FAULHABER Group offers a complete line of programmable motion controllers with various communication and performance features to fit your application. We offer controllers with multiple interfaces like RS-485, DeviceNet, or RS-232, CANopen interface. All controllers come complete...

...for use in hazardous work environments in the pharmaceutical industry as well as for processing adhesives and solvents. The FC-X scales, which are network-compatible via an RS-232 interface or an optional RS-485 bus, were exhibited by (G ottingen, Germany) at the recent Fakuma exhibition. A printer, PC...

...and DT85 models support Modbus communication via either the serial sensor port on the front of the logger (1Serial) which allows RS-232, RS-485 or RS-422 communications or the host serial port on the side of the logger (2Serial) which is RS-232 only. When using the front serial port, a custom cable...
