What is a 9-pin cable called?
What is a DB9 Connector? The DB9 connector (originally named DE-9) is an analog socket, with 9 pins, from the D-Subminiatures (D-Sub) connector family. The DB9 has the smallest “footprint” of the D-Subminiature connectors. The prefix “D” represents the D-shape of the connector shell.
What cable uses a 9-pin connector?
A DB9 cable consists of a 9-pin connector and you can use it for connecting computer peripheries like keyboards and mice.
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 Today, the DB9 has mostly been replaced by more modern interfaces such as USB, PS/2, Firewire, and others.
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 is de 9F?
Many uninterruptible power supply units have a DE-9F connector on them in order to signal to the attached computer via an RS-232 interface. Often these do not send data serially to the computer but instead use the handshaking control lines to indicate low battery, power failure, or other conditions.
Is DB9 the same as RS-232?
What is RS232 and DB9? RS232 is the definition of the serial interface, e.g. the signal voltage and duration. DB9 is the 9 pin connector. RS232 connections are frequently implemented using these connectors, but there is a 25 pin connector also.
What does DB stand for in DB9 connector?
D-sub miniature
DB-9 is an analog 9-pin plug of the D-sub miniature (D-sub) connector plug and socket family for computer and communication devices. Some uses and characteristics of the DB-9 connector are: Serial communication.
Is DB9 same as RS-232?
What is the difference between DB9 and DB25?
The D-sub connectors’ names are equivalent with the total number of pins that they can hold. For example, DB9 Series Cables contain 9 pins. However, in some cases, a DB25 connector has 4 to 5 loaded pins.
What are D connectors?
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems.
