  • RS485
    with the RS422 interface and provides a two-wire bus topology. Using an RS485 two-wire bus provides a very inexpensive network system; however, RS485 defines only the electronic signal specifications. Consequently, users must define the software protocol for RS485 two-wire communications.
  • 2.5 Mb/s Isolated RS485 Communication Interface With up to 500 mW Supplementary Power
    This application note provides a reference design for a flexible, high power RS485 interface using NEC's PS9821 digital optocouplers and an LMS1487 transceiver from National Semiconductor.
  • Serial Interface (RS232, RS422, RS485)
    Serial interfaces transmit data one bit at a time. Common standards include RS232, RS422, and RS485. The RS232 standard is approved by the Electronic Industries Association (EIA) for connecting serial devices. The device that connects to the interface is called data communication equipment (DCE
  • Designing RS-485 Circuits
    When a network needs to transfer small blocks of information over long distances, RS-485 is often the interface of choice. The network nodes can be PCs, microcontrollers, or any devices capable of asynchronous serial communications. Compared to Ethernet and other network interfaces, RS-485's
  • Eliminate the Risk of RS-485 Data Corruption
    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
  • Configuring DT8x Data Loggers to Interface with Maple Displays via Modbus
    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
  • VoIP in Industrial Networks - Implementing QoS for Reliable Voice Over Industrial Ethernet
    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
  • Utility Monitoring System at International Airport
    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
