A male DE-9 connector on an IBM PC compatible computer (with serial port symbol) used for an RS-232 serial port A female DE-9 connector on an RS-232 cable.. A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [1]
Because personal computers first used DB-25 connectors for their serial and parallel ports, when the PC serial port began to use 9-pin connectors, they were often labeled as DB-9 instead of DE-9 connectors, due to an ignorance of the fact that B represented a shell size. It is now common to see DE-9 connectors sold as DB-9 connectors.
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 ...
The current version of the standard is TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, issued in 1997. The RS-232 standard had been commonly used with serial ports and serial cables. It is still widely used in industrial communication devices.
It uses an DE-9 D-Sub connector with 9 pins (hence the name), where bi-directional communication takes place over a four wire cable according to the RS-422 standard. While nowadays all post-production editing is done with a non-linear editing system, in those days editing was done linearly, using online editing. Editing machines relied heavily ...
This was implemented in a multi-pin connector that had enough pins to support the majority of the common RS-232 pins; the first models used a 9-pin D connector, but this was quickly replaced by a mini-DIN-8 connector starting with the Macintosh Plus. The ports could be put into either RS-232 or RS-422 mode, which changes the behavior of some of ...
The TI-99/4A home computer series used a 9-pin connector that was physically identical to the Atari version, as well as being similar in terms of the devices and the way they worked. However, the port's pins were re-arranged and it used the separate grounds to select which joystick to read, so it was not directly compatible.
COM port (DE-9 connector). COM (communication port) [ 1 ] [ 2 ] is the original, yet still common, name of the serial port interface on PC-compatible computers . It can refer not only to physical ports, but also to emulated ports, such as ports created by Bluetooth or USB adapters .
