  • Migrating Applications to USB from RS-232 UART with Minimal Impact on PC Software
    The RS-232 serial interface is no longer a common port found on a personal computer (PC). This is a problem because many embedded applications use the RS-232 interface to communicate with external systems, such as PCs. A solution is to migrate the application to the Universal Serial Bus (USB
  • Essential Facts about RS232, RS485 and RS422 Serial Ports
    by USB. However, RS232 ports remain in use today in the industrial sector.
  • Industrial role for USB
    The Hi-Speed USB standard lets industrial data-collection systems hit speeds faster than those available over most LANs. The CompactDAQ data-acquisition system from National Instruments is typical of the growing number of virtual instruments that have replaced proprietary interface protocols
  • An Introduction to Programmable Attenuator Systems
    or via a computer. Depending on the model, the maximum attenuation ranges from 0 dB to 127 dB, in steps as small as 0.1 dB. The attenuator is controlled by a combination of digital inputs, an analog voltage or via USB, RS-232, Ethernet or GPIB. These devices are bi-directional, so either port can act
  • Forgot film? No problem for digital cameras
    $1,000 and uses a 16-Mbyte CompactFlash card. The card plugs into the USB port of a PC or Macintosh computer through an adapter for downloading large pictures. The camera can capture from one to 322 images on a single card, depending on the resolution and compression ratio. Vivitar's new ViviCam 3500
  • Serial Communication Overview
    Serial is a device communication protocol that is standard on almost every PC. Do not confuse it with universal serial bus (USB). Most computers include two EIA-232 based serial ports. Serial is also a common communication protocol for instrumentation in many devices, and numerous GPIB-compatible
