EIA-specified physical interface, with associated electrical signaling, between Data Circuit-terminating Equipment (DCE) and Data Terminal Equipment (DTE); the most commonly employed interface between computers and modems. Now known as EIA/TIA-232.
A set of standards specifying various electrical and mechanical signals for interfaces between computers, terminals, and modems. In personal computer world, the original PC and PC/XT used the 25-pin RS-232 With the introduction of the AT-class personal computers, the serial connector was reduced to the 9-pin version.
In asynchronous transmissions, a recommended standard interface established by the EIA. The standard defines the specific lines, timing and signal characteristics used between the computer and the peripheral device,and uses a 25-pin or 9-pin DB connector. RS-232-C is used for serial communications between a computer and a peripheral such as a printer, modem, digitzing tablet, or mouse. The maximum cable limit of 50 feet can be extended by using very high quality cable, line drivers to boost the signal, or short-haul modems. RS stands for recommended standard, and the C denotes the third revision of that standard. RS-232-C is functionally identical to the CCITT V.24 standard.
A serial-type connection, both physical and electrical, between computers and modems. (Electronics Industries Association [EIA] standards.)
An ANSI interface standard. The most commonly applied standard for the interconnection of asynchronous devices. RS-232-C uses the ubiquitous 25-pin D-plug/socket with ribbon cable, although you may come across pins/sockets with only 9 pins. There is a closely defined specification of the functions of each pin, including voltage levels etc, although for most applications four or five pins are sufficient. Used by the mini and micro manufacturers for local connection of screens and (serially) printers. Also used by robots and programmable controllers. Even IBM has been known to use it. RS-232-C is roughly equivalent to ITU-T V24.
A set of EIA standards specifying various electrical and mechanical characteristics for interfaces between computers, terminals, and modems. The standard applies to both synchronous and asynchronous binary data transmission at rates below 64 kbps.
A serial 25 wire electrical interface between a computer and a peripheral device, such as a modem, mouse, drawing tablet or printer.
A set of standards specifying various electrical and mechanical characteristics for interfaces between computers, terminals and modems. It consists of a 25-pin plug (male or female), each lead of which has a specific function such as timing, control, or the sending of data.
The Electronic Industries Association (EIA) standard for the 25-pin (or 9-pin subset) serial interface used to connect personal computers or terminals to communications equipment, such as modems and fax devices.
An Electrical Industries Association (EIA) Standard for the physical interface between Data Terminal Equipment (DTE) and Data Circuit Terminating Equipment (DCE). Back to Menu
A standard interface between a piece of equipment and a telephone circuit.
The Electronic Industries Association (EIA) standard governing serial communications over a twisted pair. Good to about 150 feet.
A technical specification published by the EIA that establishes mechanical and electrical interface requirements between DTE and DCE, employing serial binary data interchange and operating at speeds up to 19.2Kbps.
