  2. Universal synchronous and asynchronous receiver-transmitter

    en.wikipedia.org/wiki/Universal_synchronous_and...

    The USART's synchronous capabilities were primarily intended to support synchronous protocols like IBM's synchronous transmit-receive (STR), binary synchronous communications (BSC), synchronous data link control (SDLC), and the ISO-standard high-level data link control (HDLC) synchronous link-layer protocols, which were used with synchronous voice-frequency modems.

  3. AS-Interface - Wikipedia

    en.wikipedia.org/wiki/AS-interface

    Actuator Sensor Interface (AS-Interface or ASi) is an industrial networking solution (Physical Layer, Data access Method and Protocol) used in PLC, DCS and PC-based automation systems. It is designed for connecting simple field I/O devices (e.g. binary ON/OFF devices such as actuators, sensors, rotary encoders, analog inputs and outputs, push ...

  5. Fritzing - Wikipedia

    en.wikipedia.org/wiki/Fritzing

    Fritzing's schematic view. The software was created with inspiration from the Processing programming language and the Arduino microcontroller [6] and allows a designer, artist, researcher, or hobbyist to document their Arduino-based prototype and create a PCB layout for manufacturing.

  6. 16550 UART - Wikipedia

    en.wikipedia.org/wiki/16550_UART

    Replacement of the factory-installed 8250 UART was a common upgrade for owners of IBM PC, XT, and compatible computers when high-speed modems became available. Above 9600 baud, owners discovered that the serial ports of the computers were not able to handle a continuous flow of data without losing characters.

  7. Universal asynchronous receiver-transmitter - Wikipedia

    en.wikipedia.org/wiki/Universal_asynchronous...

    Zilog manufactured a number of Serial Communication Controllers or SCCs. Starting in the 2000s, most IBM PC compatible computers removed their external RS-232 COM ports and used USB ports that can send data faster. For users who still need RS-232 serial ports, external USB-to-UART bridges are now commonly used. They combine the hardware cables ...

  8. SERCOS III - Wikipedia

    en.wikipedia.org/wiki/SERCOS_III

    For basic Slaves, such as I/O devices, EasySlave-IO, a license-free bitstream variant of the EasySlave is available. A product that uses an Arduino board as a rapid prototype platform for an application, plus a corresponding shield (add-on module) with a Sercos EasySlave FPGA, plus other peripheral components, is available.

  9. Serial port - Wikipedia

    en.wikipedia.org/wiki/Serial_port

    A male D-subminiature connector used for an RS-232 serial port on an IBM PC compatible computer along with the serial port symbol. A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [1]
