VGA connector

A connector as it is commonly known (other names include RGB connector, 15, mini sub D15 and mini D15) is a three-row 15 pin . There are four versions: and pinouts, the far older and less flexible , and a used for laptops.

The common 15-pin VGA connector found on most video cards, computer monitors, which support VGA connections, and other devices, is almost universally called "HD-15". HD stands for "high-density", which distinguishes it from connectors having the same form factor but only 2 rows of pins. However, this connector is often incorrectly referred to as a or HDB-15.

"VGA connectors" and their associated cabling are always used solely to carry analog RGBHV (red - green - blue - horizontal sync - vertical sync) video signals along with digital clock and data.

Where size is a constraint (such as laptops) a port can sometimes be found in place of the full-sized VGA connector

                                                                               

D-subminiature(D-sub)

The D-subminiature or D-sub is a common type of electrical connector used particularly in computers. Calling them "subminiature" was appropriate when they were first introduced, but today they are among the largest common connectors used in computers.

                                             

Description and nomenclature

A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, some screening against electromagnetic interference, and ensures correct orientation. The part containing pin contacts is called the male connector or plug, while that containing socket contacts is called the female connector or socket. The socket's shield fits tightly inside the plug's shield. The shields are connected to the overall screens of the cables (when screened cables are used), creating an electrically continuous screen covering the whole cable and connector system.

D-subminiature connectors were invented by ITT Cannon, part of ITT Corporation, in 1952. Cannon's part-numbering system uses a D as the prefix for the whole series, followed by a letter denoting the shell size (A=15 pin, B=25 pin, C=37 pin, D=50 pin, E=9 pin), followed by the actual number of pins, followed by the gender (P=plug, S=socket).  For example, DB25 denotes a D-sub with a 25 position shell size and a 25 position contact configuration. The contacts in these connectors are spaced approximately 0.108 inches (2.74 mm) apart with the rows spaced 0.112 inches (2.84 mm) apart.

                                       

DA15S connectors are used for PC joystick connectors, where each DA15 connector supports two joysticks each with two analog axes and two buttons. In other words, one DA15S "game adapter" connector has 4 analog potentiometer inputs and 4 digital switch inputs. This interface is strictly input-only, though it does provide +5V DC power. Some joysticks with more than two axes and/or more than two buttons use the signals designated for both joysticks. Conversely, Y-adapter cables are available that allow two separate joysticks to be connected to a single DA15 game adapter port; if a joystick connected to one of these Y-adapters has more than two axes or buttons, only the first two of each will work. The IBM DA15 PC game connector has been modified to add a (usually MPU-401 compatible) MIDI interface, and this is often implemented in the game connectors on third-party sound cards, particularly the Sound Blaster line from Creative Labs. The "standard" straight game adapter connector (introduced by IBM) has three ground pins and four +5V power pins, and the MIDI adaptation replaces one of the grounds and one of the +5V pins, both on the bottom row of pins, with MIDI In and MIDI Out signal pins. (There is no MIDI Thru provided.) Creative Labs introduced this adaptation.

DE9 connectors are also used for some token ring and other computer networks. The DA15S was also used for the AUI connectors included on Ethernet cards in the 1980s and 1990s, albeit with a sliding latch to lock the connectors together instead of the usual hex studs with threaded holes. (The sliding latch was intended to be quicker to engage and disengage and to work in places where jack-screws could not be used for reasons of component shape.

Many uninterruptible power supply units have a DE9F 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. Such usage is not standardized between manufacturers and may require special cables to be supplied.

The complete range of D-sub connectors also includes 15-pin DA15s (two rows of 7 and 8); 37-pin DC37s (two rows of 18 and 19); and 50-pin DD50s (two rows of 17 and one of 16), the last two being used in industrial products. The 15-pin DA15 has been notably used for color video output on early Macintosh computers, and for the IBM-defined PC analog joystick connector as noted above. Finally, the early Macintosh and Apple II line of computers used a very rare 19 pin D-sub for connecting to external floppy disk drives, and the Commodore Amiga used an unusual 23-pin version for both its video output and for connecting an external floppy disk drive.

TASCAM used DB25 connectors for their multi-track recording audio equipment (TDIF), and Logitek Audio later did the same for its broadcast consoles, though with different pinouts. A few patch panels have been made which have the DB25 connectors on the back with phone jacks (or even TRS jacks) on the front, however these are normally wired for TASCAM, which is more common outside of broadcasting.

In broadcast and professional video, "parallel digital" is a digital video interface that utilizes DB25 connectors, per the SMPTE 274M specification adopted in the late 1990s. The more common SMPTE 259M "serial digital interface" (SDI) utilizes BNC connectors for digital video signal transfer.

A smaller type of connector derived from the D-subminiature, and about half the linear size, is called the microminiature D, or , which is a trademark of ITT Cannon. This connector is used in industrial instrumentation products. A few manufacturers make connectors, which are about half the size again.
