Introduction
Hello, welcome to the PC Connectors Pin-Outs ebook. The majority of
the common PC pin-outs are contained within this ebook with a vast
selection of photos/images.
The purpose of this book is to contain a set of PC connections in one
place as a quick guide as online connections are not always accessable.
This eBook has grown from a purely textual document to an illustrated
guide with the additional of new interfaces as they become available.
Additional information or specific pinouts for other computers are
available from Wiki’s or other online sources.

ATX 20/24-pin Power
Supply Connector
ATX 20/24-pin Power Supply Connector
The ATX specification requires the power supply to produce three
main outputs, +3.3 V, +5 V and +12 V. Low-power -12 V and 5 VSB
(standby) supplies are also required. A -5 V output was originally
required, but it is now completely obsolete.
Originally the motherboard was powered by one 20-pin connector. An
ATX power supply provides a number of peripheral power connectors,
and (in modern systems) two connectors for the motherboard: a 4-pin
auxiliary connector providing additional power to the CPU, and a main
24-pin power supply connector, an extension of the original 20-pin
version.
See figure 1 for 24-pin ATX power connector.
28/04/2011 ©Easy PC Online Return to Contents Page 6
Pins 8, 13, and 16 (shaded) are
control signals, not power:
"Power On" is pulled up to +5V by
the PSU, and must be driven low
to turn on the PSU.
"Power good" is low when other
outputs have not yet reached, or
are about to leave, correct
voltages.
The "+3.3 V sense" line is for
remote sensing.[7]
Pin 20 (formerly −5V, white wire)
is absent in current power
supplies; it was optional in ATX
and ATX12V ver. 1.2, and deleted
as of ver. 1.3.
The right-hand pins are
numbered 11–20 in the 20-pin
version.

GND.
2. Pins 1, 2, and 3 are optional as well, as evidenced by some adapter
Cables that connect the drives to older PSUs. These are usually Y-
Adapters that have the four-pin drive connector on the other end.

The SATA standard defines a data cable with seven conductors (3 grounds and 4
active data lines in two pairs) and 8 mm wide wafer connectors on each end.
SATA cables can have lengths up to 1 metre (3.3 ft), and connect one
motherboard socket to one hard drive. PATA ribbon cables, in comparison,
connect one motherboard socket to one or two hard drives, carry either 40 or 80
wires, and are limited to 45 centimetres (18 in) in length by the PATA
specification (however, cables up to 90 centimetres (35 in) are readily available).
Thus, SATA connectors and cables are easier to fit in closed spaces, and reduce
obstructions to air cooling. They are more susceptible to accidental unplugging
and breakage than PATA, but cables can be purchased that have a locking
feature, whereby a small (usually metal) spring holds the plug in the socket.
Floppy Disk Drive
Connector
Floppy Disk Drive Connector
The Floppy cable twist is used to determine which drive [in a multi-
drive] system is drive 'A' or 'B' [also called drive '1' or '2']. From the pin
out table below; the swapped pins determine the floppy drive enabled,
and which motor is enabled. The pins are line 10, line 12, line 14, and
line 16, while the other lines in the twist are ground lines. In general, the
Floppy drive ships with a jumper positioned so that the drive is a 'B'
drive, the cable does the rest. There may be other variations [dual twist]
in the cable, this page explores one "common" implementation.

Connector
CPU and System FAN Connector
1. Chassis and CPU fans may use either3-pin or 4-pin power connectors.
2. Pin connectors are usually used for the smaller chassis fans with lower
power consumption. 4-pin connectors are usually used by CPU fans with
higher power consumption. Fans and on-board fan headers are
backwards compatible.
3. When using a 3-pin power connector with a 4-pin fan header, the fan
will always be on; there is no fan control.
Proper fan connector placement is shown in the figures below:
• Fan has a 3-pin power connector; desktop board has a 4-pin fan

PCI General description
PCI General description
Conventional PCI (PCI is an initialism formed from Peripheral Component
Interconnect, part of the PCI Local Bus standard and often shortened to PCI) is a
computer bus for attaching hardware devices in a computer. These devices can
take either the form of an integrated circuit fitted onto the motherboard itself,
called a planar device in the PCI specification, or an expansion card that fits into a
slot. The PCI Local Bus is common in modern PCs, where it has displaced ISA and
VESA Local Bus as the standard expansion bus, and it also appears in many other
computer types. Despite the availability of faster interfaces such as PCI-X and PCI
Express, conventional PCI remains a very common interface.
The PCI specification covers the physical size of the bus (including the size and
spacing of the circuit board edge electrical contacts), electrical characteristics, bus
timing, and protocols. The specification can be purchased from the PCI Special
Interest Group (PCI-SIG).
Typical PCI cards used in PCs include: network cards, sound cards, modems, extra
ports such as USB or serial, TV tuner cards and disk controllers. Historically video
cards were typically PCI devices, but growing bandwidth requirements soon
outgrew the capabilities of PCI. PCI video cards remain available for supporting
extra monitors and upgrading PCs that do not have any AGP or PCI Express slots.
Many devices traditionally provided on expansion cards are now commonly
integrated onto the motherboard itself, meaning that modern PCs often have no
cards fitted. However, PCI is still used for certain specialized cards, although many
tasks traditionally performed by expansion cards may now be performed equally
well by USB devices.

Most lines are connected to each slot in parallel. The exceptions are:
Each slot has its own REQ# output to, and GNT# input from the motherboard arbiter.
Each slot has its own IDSEL line, usually connected to a specific AD line.
TDO is daisy-chained to the following slot's TDI. Cards without JTAG support must connect TDI to TDO so as not to break the chain.
PRSNT1# and PRSNT2# for each slot have their own pull-up resistors on the motherboard. The motherboard may (but does not have to)
sense these pins to determine the presence of PCI cards and their power requirements.
REQ64# and ACK64# are individually pulled up on 32-bit only slots.
The interrupt lines INTA# through INTD# are connected to all slots in different orders. (INTA# on one slot is INTB# on the next and INTC#
on the one after that.)
PCI Connection /
Additional info
PCI Connection / Additional info
64-bit PCI extends this by an additional 32 contacts on each side which
provide AD[63:32], C/BE[7:4]#, the PAR64 parity signal, and a number of
power and ground pins.
28/04/2011 ©Easy PC Online Return to Contents Page 18
IOPWR is +3.3V or +5V, depending on the backplane. The slots also have a ridge in one of two places
which prevents insertion of cards that do not have the corresponding key notch, indicating support for
that voltage standard. Universal cards have both key notches and use IOPWR to determine their I/O
signal levels.
The PCI SIG strongly encourages 3.3 V PCI signalling, requiring support for it since standard revision
2.3, but most PC motherboards use the 5 V variant. Thus, while many currently available PCI cards
support both, and have two key notches to indicate that, there are still a large number of 5 V-only
cards on the market.
The M66EN pin is an additional ground on 5V PCI busses found in most PC motherboards. Cards and
motherboards that do not support 66 MHz operation also ground this pin. If all participants support 66
MHz operation, a pull-up resistor on the motherboard raises this signal high and 66 MHz operation is
enabled.
At least one of PRSNT1# and PRSNT2# must be grounded by the card. The combination chosen
indicates the total power requirements of the card (25 W, 15 W, or 7.5 W).
SBO# and SDONE are signals from a cache controller to the current target. They are not initiator
outputs, but are coloured that way because they are target inputs.

PCIe (PCI Express)
Description
PCIe (PCI Express) Description
PCI Express (Peripheral Component Interconnect Express), officially abbreviated as
PCIe, is a computer expansion card standard designed to replace the older PCI,
PCI-X, and AGP bus standards. PCIe has numerous improvements over the
aforementioned bus standards, including higher maximum system bus throughput,
lower I/O pin count and smaller physical footprint, better performance-scaling for
bus devices, a more detailed error detection and reporting mechanism, and native
hot plugging. More recent revisions of the PCIe standard support hardware I/O
virtualization.
The PCIe electrical interface is also used in a variety of other standards, most
notably ExpressCard, a laptop expansion card interface.
Format specifications are maintained and developed by the PCI-SIG (PCI Special
Interest Group), a group of more than 900 companies that also maintain the
Conventional PCI specifications. PCIe 3.0 is the latest standard for expansion cards
that is available on mainstream personal computers.
Applications
PCI Express is used in consumer, server, and industrial applications, as a
motherboard-level interconnect (to link motherboard-mounted peripherals) and
as an expansion card interface for add-in boards.
In virtually all modern PCs, from consumer laptops and desktops to enterprise data
servers, the PCIe bus serves as the primary motherboard-level interconnect,
connecting the host system processor with both integrated-peripherals (surface
mounted ICs) and add-on peripherals (expansion cards.) In most of these systems,
the PCIe bus co-exists with one or more legacy PCI busses, for backward
compatibility with the large body of existing PCI peripherals.

Serial or COM Port Description
28/04/2011 ©Easy PC Online Return to Contents Page 26
In computing, a serial port is a serial communication physical interface
through which information transfers in or out one bit at a time (contrast
parallel port). Throughout most of the history of personal computers, data
transfer through serial ports connected the computer to devices such as
terminals and various peripherals.
While the RS-232 standard originally specified a 25-pin D-type connector,
many designers of personal computers chose to implement only a subset
of the full standard: they traded off compatibility with the standard
against the use of less costly and more compact connectors (in particular
the DE-9 version used by the original IBM PC-AT). The desire to supply
serial interface cards with two ports required that IBM reduce the size of
the connector to fit onto a single card back panel. A DE-9 connector also
fits onto a card with a second DB-25 connector that was similarly changed
from the original Centronics-style connector. Starting around the time of
the introduction of the IBM PC-AT, serial ports were commonly built with a
9-pin connector to save cost and space. However, presence of a 9-pin D-
subminiature connector is neither necessary nor sufficient to indicate use
of a serial port, since this connector was also used for video, joysticks, and
other purposes.

A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15
connector. The 15-pin VGA connector is found on many video cards,
computer monitors, and some high definition television sets. On laptop
computers or other small devices, a mini-VGA port is sometimes used in
place of the full-sized VGA connector.
DE-15 is also conventionally called RGB connector, D-sub 15, mini sub D15,
mini D15, DB-15, HDB-15, HD-15 or HD15 (High Density, to distinguish it
from the older and less flexible DE-9 connector used on older VGA cards,
which has the same shell size but only two rows of pins).

The Digital Visual Interface (DVI) is a video interface standard covering the
transmission of video between a source device (such as a personal
computer) and a display device. The DVI standard has achieved
widespread acceptance in the PC industry, both in desktop PCs and
monitors. Most contemporary retail desktop PCs and LCD monitors feature
a DVI interface, and many other devices (such as projectors and consumer
televisions) support DVI indirectly through HDMI, another video interface
standard. Most laptops still have legacy VGA and, in some models, HDMI
ports, but not displayport or DVI.
DVI was developed by an industry consortium, the Digital Display Working
Group (DDWG) to replace the "legacy analog technology" VGA connector
standard. It is designed for carrying uncompressed digital video data to a
display. It is partially compatible with the High-Definition Multimedia
Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog
mode (DVI-A). It is also still found in some consumer television sets,
despite having been superseded in this application by HDMI, another
video interface standard.

S-Video Description
S-Video Description
Separate Video, more commonly known as S-Video and Y/C, and still
often referred to by JVC (who introduced the DIN-connector pictured) as
both an S-VHS connector and as Super Video is an analog video
transmission scheme, in which video information is encoded on two
channels: luma (luminance, intensity) and chroma (color). This is in
contrast with lower-quality composite video, in which video information
is encoded on one channel, and higher-quality component video, in
which video information is encoded on three channels. S-Video carries
standard definition video (typically at 480i or 576i resolution), but does
not carry audio on the same cable.
The 4-pin mini-DIN connector (overleaf) is the most common of several
S-Video connector types. Other S-Video connector variants include 7-pin
locking "dub" connectors used on many professional S-VHS machines,
and dual "Y" and "C" BNC connectors, often used for S-Video patch bays.
Early Y/C video monitors often used RCA connectors that were
switchable between Y/C and composite video input. Though the
connectors are different, the Y/C signals for all types are compatible.

HDMI (High-Definition Multimedia Interface) is a compact audio/video
interface for transmitting uncompressed digital data. It is a digital
alternative to consumer analog standards, such as radio frequency (RF)
coaxial cable, composite video, S-Video, SCART, component video, D-
Terminal, or VGA. HDMI connects digital audio/video sources (such as
set-top boxes, upconvert DVD players, HD DVD players, Blu-ray Disc
players, AVCHD camcorders, personal computers (PCs), video game
consoles such as the PlayStation 3 and Xbox 360, and AV receivers) to
compatible digital audio devices, computer monitors, video projectors,
and digital televisions.

eSATAp (power over eSATA) is a high speed connection for External
storage devices. External storage devices includes portable hard disks
(HDD), solid-state drives (SSD) and network-attached storage (NAS).
eSATAp port can be found on notebook PCs and desktop machines.
An eSATAp (Power over eSATA or eSATA/USB) port is backward
compatible with eSATA and USB devices. Notebooks/motherboards
manufacturers with eSATAp port includes Dell, Gigabyte Technology,
Sony, Toshiba, Lenovo, HP, MSI, Acer and Asus.

Game/Joystick/MIDI Port Pinout
The game port was the traditional connector for video game input
devices on x86-based PCs. Since about 1990, the game port has usually
been integrated with a PC I/O or sound card, either ISA or PCI, or as an
on-board feature of some motherboards; before that, it was usually on a
dedicated ISA card. Microsoft has discontinued game port support with
Windows Vista,[1] so it is probable that manufacturers will cease to
produce boards with this connector. However, it's still entirely possible
to provide third-party drivers that will work with the game port, and
some companies that have produced game port cards in the past do so.
USB adapters that allow gameport controllers to work have also been
available.

  • 6. ATX 20/24-pin Power Supply Connector ATX 20/24-pin Power Supply Connector The ATX specification requires the power supply to produce three main outputs, +3.3 V, +5 V and +12 V. Low-power -12 V and 5 VSB (standby) supplies are also required. A -5 V output was originally required, but it is now completely obsolete. Originally the motherboard was powered by one 20-pin connector. An ATX power supply provides a number of peripheral power connectors, and (in modern systems) two connectors for the motherboard: a 4-pin auxiliary connector providing additional power to the CPU, and a main 24-pin power supply connector, an extension of the original 20-pin version. See figure 1 for 24-pin ATX power connector. 28/04/2011 ©Easy PC Online Return to Contents Page 6 Pins 8, 13, and 16 (shaded) are control signals, not power: "Power On" is pulled up to +5V by the PSU, and must be driven low to turn on the PSU. "Power good" is low when other outputs have not yet reached, or are about to leave, correct voltages. The "+3.3 V sense" line is for remote sensing.[7] Pin 20 (formerly −5V, white wire) is absent in current power supplies; it was optional in ATX and ATX12V ver. 1.2, and deleted as of ver. 1.3. The right-hand pins are numbered 11–20 in the 20-pin version.

  • 11. SATA Connector SATA Connector 28/04/2011 ©Easy PC Online Return to Contents Page 11 The SATA standard defines a data cable with seven conductors (3 grounds and 4 active data lines in two pairs) and 8 mm wide wafer connectors on each end. SATA cables can have lengths up to 1 metre (3.3 ft), and connect one motherboard socket to one hard drive. PATA ribbon cables, in comparison, connect one motherboard socket to one or two hard drives, carry either 40 or 80 wires, and are limited to 45 centimetres (18 in) in length by the PATA specification (however, cables up to 90 centimetres (35 in) are readily available). Thus, SATA connectors and cables are easier to fit in closed spaces, and reduce obstructions to air cooling. They are more susceptible to accidental unplugging and breakage than PATA, but cables can be purchased that have a locking feature, whereby a small (usually metal) spring holds the plug in the socket.
  • 12. Floppy Disk Drive Connector Floppy Disk Drive Connector The Floppy cable twist is used to determine which drive [in a multi- drive] system is drive 'A' or 'B' [also called drive '1' or '2']. From the pin out table below; the swapped pins determine the floppy drive enabled, and which motor is enabled. The pins are line 10, line 12, line 14, and line 16, while the other lines in the twist are ground lines. In general, the Floppy drive ships with a jumper positioned so that the drive is a 'B' drive, the cable does the rest. There may be other variations [dual twist] in the cable, this page explores one "common" implementation. 28/04/2011 ©Easy PC Online Return to Contents Page 12

Pin connectors are usually used for the smaller chassis fans with lower power consumption. 4-pin connectors are usually used by CPU fans with higher power consumption. Fans and on-board fan headers are backwards compatible. 3. When using a 3-pin power connector with a 4-pin fan header, the fan will always be on; there is no fan control. Proper fan connector placement is shown in the figures below: • Fan has a 3-pin power connector; desktop board has a 4-pin fan header: • Fan has a 4-pin power connector; desktop board has a 3-pin fan header: 28/04/2011 ©Easy PC Online Return to Contents Page 14
  • 15. PCI General description PCI General description Conventional PCI (PCI is an initialism formed from Peripheral Component Interconnect, part of the PCI Local Bus standard and often shortened to PCI) is a computer bus for attaching hardware devices in a computer. These devices can take either the form of an integrated circuit fitted onto the motherboard itself, called a planar device in the PCI specification, or an expansion card that fits into a slot. The PCI Local Bus is common in modern PCs, where it has displaced ISA and VESA Local Bus as the standard expansion bus, and it also appears in many other computer types. Despite the availability of faster interfaces such as PCI-X and PCI Express, conventional PCI remains a very common interface. The PCI specification covers the physical size of the bus (including the size and spacing of the circuit board edge electrical contacts), electrical characteristics, bus timing, and protocols. The specification can be purchased from the PCI Special Interest Group (PCI-SIG). Typical PCI cards used in PCs include: network cards, sound cards, modems, extra ports such as USB or serial, TV tuner cards and disk controllers. Historically video cards were typically PCI devices, but growing bandwidth requirements soon outgrew the capabilities of PCI. PCI video cards remain available for supporting extra monitors and upgrading PCs that do not have any AGP or PCI Express slots. Many devices traditionally provided on expansion cards are now commonly integrated onto the motherboard itself, meaning that modern PCs often have no cards fitted. However, PCI is still used for certain specialized cards, although many tasks traditionally performed by expansion cards may now be performed equally well by USB devices. 28/04/2011 ©Easy PC Online Return to Contents Page 15

  • 17. PCI Pinouts PCI Pinouts 28/04/2011 ©Easy PC Online Return to Contents Page 17 Most lines are connected to each slot in parallel. The exceptions are: Each slot has its own REQ# output to, and GNT# input from the motherboard arbiter. Each slot has its own IDSEL line, usually connected to a specific AD line. TDO is daisy-chained to the following slot's TDI. Cards without JTAG support must connect TDI to TDO so as not to break the chain. PRSNT1# and PRSNT2# for each slot have their own pull-up resistors on the motherboard. The motherboard may (but does not have to) sense these pins to determine the presence of PCI cards and their power requirements. REQ64# and ACK64# are individually pulled up on 32-bit only slots. The interrupt lines INTA# through INTD# are connected to all slots in different orders. (INTA# on one slot is INTB# on the next and INTC# on the one after that.)
  • 18. PCI Connection / Additional info PCI Connection / Additional info 64-bit PCI extends this by an additional 32 contacts on each side which provide AD[63:32], C/BE[7:4]#, the PAR64 parity signal, and a number of power and ground pins. 28/04/2011 ©Easy PC Online Return to Contents Page 18 IOPWR is +3.3V or +5V, depending on the backplane. The slots also have a ridge in one of two places which prevents insertion of cards that do not have the corresponding key notch, indicating support for that voltage standard. Universal cards have both key notches and use IOPWR to determine their I/O signal levels. The PCI SIG strongly encourages 3.3 V PCI signalling, requiring support for it since standard revision 2.3, but most PC motherboards use the 5 V variant. Thus, while many currently available PCI cards support both, and have two key notches to indicate that, there are still a large number of 5 V-only cards on the market. The M66EN pin is an additional ground on 5V PCI busses found in most PC motherboards. Cards and motherboards that do not support 66 MHz operation also ground this pin. If all participants support 66 MHz operation, a pull-up resistor on the motherboard raises this signal high and 66 MHz operation is enabled. At least one of PRSNT1# and PRSNT2# must be grounded by the card. The combination chosen indicates the total power requirements of the card (25 W, 15 W, or 7.5 W). SBO# and SDONE are signals from a cache controller to the current target. They are not initiator outputs, but are coloured that way because they are target inputs.

  • 20. PCIe (PCI Express) Description PCIe (PCI Express) Description PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe, is a computer expansion card standard designed to replace the older PCI, PCI-X, and AGP bus standards. PCIe has numerous improvements over the aforementioned bus standards, including higher maximum system bus throughput, lower I/O pin count and smaller physical footprint, better performance-scaling for bus devices, a more detailed error detection and reporting mechanism, and native hot plugging. More recent revisions of the PCIe standard support hardware I/O virtualization. The PCIe electrical interface is also used in a variety of other standards, most notably ExpressCard, a laptop expansion card interface. Format specifications are maintained and developed by the PCI-SIG (PCI Special Interest Group), a group of more than 900 companies that also maintain the Conventional PCI specifications. PCIe 3.0 is the latest standard for expansion cards that is available on mainstream personal computers. Applications PCI Express is used in consumer, server, and industrial applications, as a motherboard-level interconnect (to link motherboard-mounted peripherals) and as an expansion card interface for add-in boards. In virtually all modern PCs, from consumer laptops and desktops to enterprise data servers, the PCIe bus serves as the primary motherboard-level interconnect, connecting the host system processor with both integrated-peripherals (surface mounted ICs) and add-on peripherals (expansion cards.) In most of these systems, the PCIe bus co-exists with one or more legacy PCI busses, for backward compatibility with the large body of existing PCI peripherals. 28/04/2011 ©Easy PC Online Return to Contents Page 20

  • 26. Serial or COM Port Description Serial or COM Port Description 28/04/2011 ©Easy PC Online Return to Contents Page 26 In computing, a serial port is a serial communication physical interface through which information transfers in or out one bit at a time (contrast parallel port). Throughout most of the history of personal computers, data transfer through serial ports connected the computer to devices such as terminals and various peripherals. While the RS-232 standard originally specified a 25-pin D-type connector, many designers of personal computers chose to implement only a subset of the full standard: they traded off compatibility with the standard against the use of less costly and more compact connectors (in particular the DE-9 version used by the original IBM PC-AT). The desire to supply serial interface cards with two ports required that IBM reduce the size of the connector to fit onto a single card back panel. A DE-9 connector also fits onto a card with a second DB-25 connector that was similarly changed from the original Centronics-style connector. Starting around the time of the introduction of the IBM PC-AT, serial ports were commonly built with a 9-pin connector to save cost and space. However, presence of a 9-pin D- subminiature connector is neither necessary nor sufficient to indicate use of a serial port, since this connector was also used for video, joysticks, and other purposes.

  • 28. VGA Pinout VGA Pinout 28/04/2011 ©Easy PC Online Return to Contents Page 28 A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and some high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector. DE-15 is also conventionally called RGB connector, D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15 (High Density, to distinguish it from the older and less flexible DE-9 connector used on older VGA cards, which has the same shell size but only two rows of pins).

DVI Description and Connector DVI Description and Connector 28/04/2011 ©Easy PC Online Return to Contents Page 29 The Digital Visual Interface (DVI) is a video interface standard covering the transmission of video between a source device (such as a personal computer) and a display device. The DVI standard has achieved widespread acceptance in the PC industry, both in desktop PCs and monitors. Most contemporary retail desktop PCs and LCD monitors feature a DVI interface, and many other devices (such as projectors and consumer televisions) support DVI indirectly through HDMI, another video interface standard. Most laptops still have legacy VGA and, in some models, HDMI ports, but not displayport or DVI. DVI was developed by an industry consortium, the Digital Display Working Group (DDWG) to replace the "legacy analog technology" VGA connector standard. It is designed for carrying uncompressed digital video data to a display. It is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A). It is also still found in some consumer television sets, despite having been superseded in this application by HDMI, another video interface standard.

  • 32. S-Video Description S-Video Description Separate Video, more commonly known as S-Video and Y/C, and still often referred to by JVC (who introduced the DIN-connector pictured) as both an S-VHS connector and as Super Video is an analog video transmission scheme, in which video information is encoded on two channels: luma (luminance, intensity) and chroma (color). This is in contrast with lower-quality composite video, in which video information is encoded on one channel, and higher-quality component video, in which video information is encoded on three channels. S-Video carries standard definition video (typically at 480i or 576i resolution), but does not carry audio on the same cable. The 4-pin mini-DIN connector (overleaf) is the most common of several S-Video connector types. Other S-Video connector variants include 7-pin locking "dub" connectors used on many professional S-VHS machines, and dual "Y" and "C" BNC connectors, often used for S-Video patch bays. Early Y/C video monitors often used RCA connectors that were switchable between Y/C and composite video input. Though the connectors are different, the Y/C signals for all types are compatible. 28/04/2011 ©Easy PC Online Return to Contents Page 32

It is a digital alternative to consumer analog standards, such as radio frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D- Terminal, or VGA. HDMI connects digital audio/video sources (such as set-top boxes, upconvert DVD players, HD DVD players, Blu-ray Disc players, AVCHD camcorders, personal computers (PCs), video game consoles such as the PlayStation 3 and Xbox 360, and AV receivers) to compatible digital audio devices, computer monitors, video projectors, and digital televisions. 28/04/2011 ©Easy PC Online Return to Contents Page 34

  • 40. Game/Joystick/MIDI Port Pinout Game/Joystick/MIDI Port Pinout The game port was the traditional connector for video game input devices on x86-based PCs. Since about 1990, the game port has usually been integrated with a PC I/O or sound card, either ISA or PCI, or as an on-board feature of some motherboards; before that, it was usually on a dedicated ISA card. Microsoft has discontinued game port support with Windows Vista,[1] so it is probable that manufacturers will cease to produce boards with this connector. However, it's still entirely possible to provide third-party drivers that will work with the game port, and some companies that have produced game port cards in the past do so. USB adapters that allow gameport controllers to work have also been available. 28/04/2011 ©Easy PC Online Return to Contents Page 40
