  • Cable Selection for RS422 and RS485 Systems
    Selecting data cable for an RS-422 or RS-485 system isn't difficult, but often gets lost in the shuffle of larger system issues. Care should be taken, however, because intermittent problems caused by marginal cable can be very difficult to troubleshoot.
  • The Elements of an RS-422 and RS-485 System
    Learn the important aspects. of RS-422/485 system design. The Elements of an RS-422 and RS-485 System: - System configuration. - Cabling selection. - Transient protection. - Software. - Device selection. ./89ed196c-47c0-4b0c-8e58-5cba5189b5f4 The Elements of an RS-422 and RS-485 System. Learn
  • The State of Industrial Serial Communication
    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. Thoughts on industrial serial communication
  • RS485 Application
    The EIA/TIA RS-485 communications standard, an upgrade of RS-422, supports 32 devices (driver/receiver pairs) in a party line or multi-drop mode, on a cable of up to 4,000 feet for balanced differential signal transmissions at a common-mode voltage (Vcm) of -7 to +12 V. You can internally
  • Lightning and Surge Protectors Tutorial
    Lightning and surge protectors are devices whose purpose is to eliminate transients (spikes) through a conductor (typically a cable) which are induced by nearby lightning activity. They are used to prevent damage to valuable electronic equipment from these high-voltage surges and spikes. Lightning
  • Dataline Surge Protection: Stop Fried Boards, Corrupted Data
    are appropriate. These devices typically add some capacitive load to the data lines, similar to adding additional cable to the system. This should be considered when designing a system by reducing the total allowable line length. Several hundred feet is usually an adequate figure in RS-422 and RS-485 systems.
  • Designing RS-485 Circuits
    hardware and protocol requirements are simpler and cheaper. The RS-485 standard is flexible enough to provide a choice of drivers, receivers, and other components depending on the cable length, data rate, number of nodes, and the need to conserve power. 9901018-pub you use prebuilt cards
  • 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
