    en.wikipedia.org/wiki/RS-232

    In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data. It formally defines signals connecting between a DTE ( data terminal equipment ) such as a computer terminal or PC , and a DCE ( data circuit-terminating equipment or data communication ...

    en.wikipedia.org/wiki/Serial_cable

    Serial cables are typically used for RS-232 communication. A serial cable or RS-232 cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable.

    en.wikipedia.org/wiki/Null_modem

    A null modem adapter. Null modem is a communication method to directly connect two DTEs (computer, terminal, printer, etc.) using an RS-232 serial cable.The name stems from the historical use of RS-232 cables to connect two teleprinter devices or two modems in order to communicate with one another; null modem communication refers to using a crossed-over RS-232 cable to connect the teleprinters ...

  7. Data circuit-terminating equipment - Wikipedia

    en.wikipedia.org/wiki/Data_Circuit-Terminating...

    Although the terms are most commonly used with RS-232, several data communication standards define different types of interfaces between a DCE and a DTE. The DCE is a device that communicates with a DTE device in these standards. Standards that use this nomenclature include: Federal Standard 1037C, MIL-STD-188; RS-232

  8. Digital current loop interface - Wikipedia

    en.wikipedia.org/wiki/Digital_current_loop_interface

    RS-232 / Current loop converter. For serial communications, a current loop is a communication interface that uses current instead of voltage for signaling. Current loops can be used over moderately long distances (tens of kilometres), and can be interfaced with optically isolated links.

  9. USB-to-serial adapter - Wikipedia

    en.wikipedia.org/wiki/USB-to-serial_adapter

    FTDI US232R : USB to RS-232 cable. A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232, RS-485, RS-422, or TTL-level UART serial data.
