What is a 9 pin cable used for?
DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also they are used on DB9 cable assemblies for data connectivity. Today, the DB9 has mostly been replaced by more modern interfaces such as USB, PS/2, Firewire, and others.
What computer cable has 9 pins?
Video Monitor Ports Many older desktop PCs have a 9-pin, female VGA outlet used to connect their video card or onboard, integrated graphics system to an external monitor.
What is a 9 pin adapter?
This 9 pin adapter will turn your 9 pin cable into a 6 pin cable. This cable is universal and works with all diagnostic tools and cables. The 9 pin connection works with all diagnostic tool and cable ends from 1990 to current year.
Which ports have 9 pin male connectors?
The 9-pin DE-9 connector has been used by most IBM-compatible PCs since the Serial/Parallel Adapter option for the PC-AT, where the 9-pin connector allowed a serial and parallel port to fit on the same card. This connector has been standardized for RS-232 as TIA-574.
What does a DB9 connector look like?
A DB9 cable consists of a 9-pin connector and you can use it for connecting computer peripheries like keyboards and mice. The name of this connector has come from its trapezoidal shape which looks like the letter “D”.
How many pins does a VGA cable have?
15-pin
There are two types of VGA cables: 14-pin and 15-pin. 14-pin cables will work in most applications, but 15-pin cables may be required for wider display compatibility. This product is a 15-pin VGA cable.
What is the 9 pin RS232 cable pinout?
RS232 serial port monitoring hardware stands out for a number of reasons, including its 9 pin RS232 pinout. This pinout can make a world of difference for successful RS232 serial communications. Thus, it is important to understand how the 9 pin RS232 cable pinout can affect the flow of serial data between devices.
How many pins are there in a serial port?
The first serial ports were DB-25s and had 25 pins. These were bulky and were replaced by the more space efficient DB-9 with its nine pins. Serial ports are controlled by a special chip – UART (Universal Asynchronous Receiver Transmitter), which are found on the computer’s motherboard or an expansion card.
What is a DB9 port on a computer?
RS-232 DB9 Overview The RS232C DE-9, often mistakenly referred to as a DB-9 port used to be the industry standard for serial data transmission. A RS-232 serial port was a standard feature of personal computers as it was the preferred way to connect modems, keyboards, mice, external storage and many other peripheral devices.
