Refers to a serial cable, line or port. It is the computer port that has nine pins, also called DB-9.
A standard interface connection that provides for only modest transmission rates & is often used with modems. RS232 cables have 25-pin, D-type connectors on either end.
itis a standard to specified signal voltages, signal timing, signal function, a protocol for information exchange, and mechanical connectors.
Robust but outdated signalling protocol using 2 pairs.
A common physical interface standard for the interconnection of devices. The standard allows for a single device to be connected at baud rates up to 9600 bps, at distances up to 15 meters.
Usually refers to serial data transmission, the most common type of computer interface. RS232 is ideal for data transmission for up to about 50 feet at frequencies of 0 through 20 kbps. Connections are usually with 25 pin D shaped or smaller 9 pin connectors. Often used in access systems to conect system to a computer or printer. For longer distance wire runs, shielded and or low capacitance wire is used.
The standard port on POS device used to support a wireless transmission via VSAT, Frame, VPN or Motient. May also be used with various peripheral devices i.e. Check Reader or Personal Computer.
A TIA/EIA standard for serial transmission between computers and UPS or other peripheral devices.
A serial communication standard data port found on most receivers.
Recommended Standard #232 (ANSI Electrical Interface for Serial Communication
An Electrical Industries Association (EIA) standard which is the most common way of linking data devices together. The connection to an RS232 is usually limited to a maximum of 50 feet. It is a standard of binary data interchange between a DTE (Data Terminal Equipment) and a DCE (Data Communication Equipment).
Connection socket commonly found on computers. Some cellphones have the ability to be connected to a PC through this socket to facilitate the updating of personal directories, or for writing SMS text messages.
This is the communication standard that applies to PC serial communications. RS232 is commonly used as the mechanism for sending instructions that control PTZ security camera movement.
Scanner or base is connected to the computers serial or RS232 port. When a barcode is scanned the string representing the barcode is sent to the serial port. Software is required to read the serial data and bring it into your application.
A primitive means of communication between computers that dates back to the time of teletypes and horse-drawn carriages. Any two computers attempting to talk via this so-called "standard" can be guaranteed to have plugs with differing numbers of pins and of incompatible gender, be using a different kind of handshaking and baud rate, and be in complete disagreement about whether "carriage return" means what it says or something entirely different. Once you've sorted that out it still doesn't work and that's because you either used a null modem when you shouldn't have, or vice versa. It's usually simpler to take a photograph of what's on the screen of the first computer and then feed it into the second computer using a scanner.
The standard port on POS equipment to support a traditional phone line.
This is short for Recommend Standard 232C, which is standard communication interface approved by the EIA (Electronic Industries Alliance) for connecting Serial Devices. RS-422 and RS-485 are other standards as well.
RS232 is an electrical signaling specification published by the Electronic Industries Association (EIA). Although not identified in the specification, the 25-pin (DB25) connector, with specific pin assignments, is commonly accepted as "the RS232 connector or the serial connector."
The electronic voltage and timing interface definition for the connection of electronic equipment
A technical specification published by the Electronic Industries Association that specifies the mechanical and electrical characteristics of the interface for connecting data terminal equipment (DTE) and data circuit terminating equipment (DCE). It defines interface circuit functions and their corresponding connector pin assignments. Usually the serial port of a PC uses this standard for connection to communication devices.
A connection that allows transfer of data. Suitably equipped phones can be connected to a PC using this method.
A standard interface between a computer input/output port and a peripheral device. Signal properties including time duration, voltage, and current, are specified by the Electronic Industries Association.
A standard for serial transmission of data between two devices. This defines the pin and plug in terms of size, shape and number of pins. An interface based on the RS232 standard.
A commonly used computer serial interface. Saturation (color) - The vividness of a color. It is directly related to the amplitude of the chrominance signal.
A generic serial communications protocol commonly used to exchange data over short distances between different devices. Very robust but only to about 50 feet in distance without amplification or line loss. See also RS422, RS485.
RS232 is the name given to a standard which defines the electrical and physical characteristics of a serial interface. The standard originated in America but is now widely accepted throughout the world.
An Electronic Industry Association (EIA) standard that defines a computer interface for connecting serial communication devices such as printers and modems. 66 Block - A terminal block where up to 4 sets of up to 25 pairs of wire can be interconnected. The installer uses a special "punch down" tool to connect the wires.
The most common asynchronous serial line standard, defining pin use of connectors (s. serial interface).
