What is a DB25 connector?
A DB25 connector is an established parallel port connection in computers often referred to as a printer port. These 25-pin d-subs offer rugged connections of peripherals and have excellent shock and vibration resistance.
Is dsub the same as DB25?
D-Subminiature or D-sub is a common type of electrical connector. They are named their own D-shaped metal shields. When introduced, D-subs is one of the smallest connectors used in a computer system. DB25 is one of the variants of the D-Sub connector.
What does DB25 stand for?
What Does DB-25 Mean? DB-25 is part of the D-subminiature (D-Sub) connector plug and socket family for computer and communication devices. DB-25 is a 25-pin electrical connector for serial and parallel computer ports. It is arranged in rows of two with one 13-pin row above another 12-pin row.
Is DB25 serial or parallel?
Techopedia Explains DB-25 The DB-25 connector is used for parallel, small computer system interface (SCSI), or RS-232 serial applications. In parallel applications, DB-25 connectors are known as IEEE-1284 Type A connectors.
What does db25 stand for?
What is the name of the 25 pin female connector on the back of the computer?
The parallel port is found on the back of IBM compatible computers and is a 25-pin (type DB-25) computer interface commonly used to connect printers to the computer.
What is D-sub cable?
A D-sub connector, also called a D-sub miniature, is an electrical connector commonly used in computers. D-sub connectors feature parallel rows of connector pins, surrounded by a metal shield. The shield is shorter on one side, resembling the D English letter.
What is the difference between LPT port and COM port?
COM ports can be used to connect peripheral devices and LPT port are specifically used for connecting printers. There settings in the BIOS and Windows depend up on the system manufactures.
What is a DB15 connector?
The DB15 connector is an analog socket, with 15 pins, from the D-Subminiatures (D-Sub) connector family. The prefix “D” represents the D-shape of the connector shell. The DB15 connector is mainly used in serial and parallel ports, allowing asynchronous data transmission according to the RS-232 standard (RS-232C).
Which of the following pins of db25 connector are ground?
RS232 port (DB-25 pin). Pinout and signals for full RS232 connector
| Pin | Name | Description |
|---|---|---|
| 6 | DSR | Data Set Ready |
| 7 | GND | System Ground |
| 8 | CD | Carrier Detect |
| 9 | – | RESERVED |
Where are D-Sub connectors used?
D-sub connector types
| D-sub type | Pin layout | Notes |
|---|---|---|
| DB-25 | 13–12 | Used for parallel port connections. |
| DA-26 | 9–9–8 | |
| DA-31 | 10–11–10 | |
| DC-37 | 19–18 | Used on some Cisco, Nortel, SMC, et al., network appliances. Also used in various models of sensors, switches, satellite antennas, control systems, video hardware, security control systems, etc. |
What is the difference between DB25 and LPT?
It is also used for parallel port connections, and was originally used to connect printers, and as a result is sometimes known as a “printer port” ( LPT for short). So to avoid confusion, DB25 serial ports on computer generally have male connectors, while parallel port connectors are DB25 female plugs.
What is a DB25 port used for?
It is also used for parallel port connections, and was originally used to connect printers, and as a result is sometimes known as a printer port (LPT). To avoid confusion, DB25 serial ports on computers generally have male connectors, while parallel port connectors are DB25 female plugs.
What are the different types of DBDB connectors?
DB-xx connectors include DB-9, DB-15, DB-25, DB-50 and DB-68. The DB-25 is a public connector for connecting external modems and RS-232 serial peripherals on older IBM-compatible computers. The DB-25 female connector is the parallel port connector for most personal computers.
What is the difference between a DB5 and a DB25 connector?
D-sub connectors are usually described by the total number of pins that they can hold. In some cases, the DB25 connector can only load 4 or 5 pins; however, it is still called a “ DB25 ” connector instead of “DB4” or “DB5”.
