It consisted of several Eurocard PCB's with DIN 41612 connectors, and a backplane all based on a 19-inch rack configuration.

A backplane ( or " backplane system ") is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors forming a computer bus.

A backplane does not suffer from this problem, so its service life is limited only by the longevity of its connectors.

In addition to its dedicated I / O bus structure, the Nova backplane had wire wrap pins that could be used for non-standard connectors or other special purposes.

At the " back " of each card is one or more connectors, which plug into mating connectors on a backplane which closes the rear of the subrack.

) In spite of its basic simplicity, the use of very small modules made it an expensive machine, with a large part of the cost sunk into the small modules, the thousands of gold-plated connectors, and the complex wire-wrapped backplane.

Each optical link consists of two multimode optical fibers with ST connectors to plug into transceivers plugged into backplane wiring at each end.

Early computer busses like S-100 were essentially nothing more than the pins of the processor run out onto the backplane and then into connectors.

Futurebus systems were implemented with 9Ux280 Eurocard mechanics using 96-pin DIN connectors resulting in a backplane that supported both 16 and 32 bit bus widths.

A 3U CompactPCI backplane with J2 ( top ) and J1 ( bottom, with blue key in the middle ) connectors.

SCSI backplane with 80-pin SCA connectors.

No cable connections were permitted on the cards ; all connections were made via three uncommitted rows of backplane connectors.

Similarly, no configuration jumpers were permitted on the cards ; all setup was done by jumpers inserted on the backplane connectors or via software configuration.

Inside the unit, there is a backplane board mounted to the bottom of the case, that provides six interface slots that have the same number of pins and bus design as NuBus connectors.

The ADC, TDC and other digital electronics are typically large circuit boards with connectors at the front edge that provide input and output for digital signals, and a connector at the back that plugs into a backplane.

The designer, Ed Roberts, also had the problem of the backplane taking up too much room.

Each CPU had its own private, unshared memory, its own I / O processor, its own private I / O bus to connect to I / O controllers, and dual connections to all the other CPUs over a custom inter-CPU backplane bus called Dynabus.

The T4 model ( of which only around 10 are thought to have been produced ) had an extended 24-bit CPU and backplane bus, allowing the use of a 4MB RAM board.

Each SLT module had a socket on one edge that plugged into pins on the computer's backplane ( the exact reverse of how most other company's modules were mounted ).

The 12000 represented several internal architecture and technical changes besides the new ASIC: it had an upgraded control processor architecture ( Intel i960 moved to PowerPC 405GP ), changed the embedded operating system ( FOS v4. 0 migrated from Wind River Systems VxWorks to MontaVista Linux ), and introduced the backplane architecture ( hierarchical PCI buses with replaceable blades attached to a backplane ).

Servers commonly have a backplane to attach hot swappable hard drives ; backplane pins pass directly into hard drive sockets without cables.

Early microcomputer bus systems were essentially a passive backplane connected directly or through buffer amplifiers to the pins of the CPU.

Prior to the advent of the microprocessor, a computer was usually built in a card-cage case or mainframe with components connected by a backplane consisting of a set of slots themselves connected with wires ; in very old designs the wires were discrete connections between card connector pins, but printed circuit boards soon became the standard practice.

The S-100 bus essentially consisted of the pins of the Intel 8080 run out onto the backplane to form the single system bus.

For example, an SBC with the latest i7 processor could interface with a backplane providing up to 19 ISA slots to drive legacy I / O cards.

The 400 series included 4 expansion slots ( although a 2 slot backplane could be added to the 300 series as an official upgrade, and third parties produced their own 4 slot backplanes ) and an ST506 controller for an internal hard drive.

MIDI information could be used on the backplane that linked the elements of the workstation together, connecting the input devices to the synthesizers, or it could be sent to another device or received from another device.

It could exist within a backplane or on a cable.

VAXBI cards mounted into backplanes using a ZIF connector ; depending on the backplane design, cards could be loaded from the top or the front side of the backplane.

The backplane would be mounted vertically in a chassis oriented front to back and the plug-in SBC and cards would lay flat, protruding out both sides of the backplane.

This allowed a new device to be added easily, generally only requiring plugging a hardware interface board into the backplane, and then installing software that read and wrote to the mapped memory to control it.

The expansion card ( also expansion board, adapter card or accessory card ) in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus.

19 or more expansion cards can be installed in backplane systems.

Top-emitting OLEDs are better suited for active-matrix applications as they can be more easily integrated with a non-transparent transistor backplane.

; Inverted OLED: In contrast to a conventional OLED, in which the anode is placed on the substrate, an Inverted OLED uses a bottom cathode that can be connected to the drain end of an n-channel TFT especially for the low cost amorphous silicon TFT backplane useful in the manufacturing of AMOLED displays.

To solve this, the backplane ORs the / CFGIN and / CFGOUT signals to form the / CFGIN for the next slot (/ CFGOUT is pulled low if undriven ), which allows empty slots to be bypassed.

One drawback of reflected-wave switching is that each pulse may need to travel twice the length of the backplane ( one complete journey for the incident wave, and another for the reflected wave ), so a delay must be maintained between adjacent pulses to allow for the travel time.

A backplane reflector of small wires can just be seen left of center, most clearly at the bottom of the image.

Zone-2 is called " Fabric Agnostic " which means that any Fabric that can use 100 Ω differential signals can be used with an AdvancedTCA backplane.

The Fabric Interface on the backplane supports many different Fabrics and can be wired as a Dual-Star, Dual-Dual-Star, Mesh, Replicated-Mesh or other architectures.

Any Fabric that can use the point-to-point 100 Ω differential signals can be used with an AdvancedTCA backplane.

The AdvancedTCA definition alone defines a Fabric agnostic chassis backplane that can be used with any of the Fabrics defined in the following specifications:

Interfaces for mass storages as disk, drum, magtape, etc., were built with one interface card to be plugged at the appropriate place in the bus system, the remaining control cards ( 6-7 ) were placed in one of the backplane modules.
