Backplanes

Passive backplane is one of the components of the industrial computer and a set of expansion slots, ISA, PCI, PICMG.

Backplane, usually installed in the building of the industrial computer, but can be used independently. As a computational kernel used board computers with bus expansion ISA, PCI, PICMG 1.0, PICMG 1.0 64-bit. Board computers installed in one of the slots expansion backplane, resulting in a passive backplane becomes an extension of the internal bus computer. The use of "bundles" single board industrial computer / passive backplane instead of the standard motherboard has a number of advantages - a larger number of expansion slots, increased rates of reliability, maintainability, vibration resistance.

Active backplane can support a large number of slots PCI (7, 12, 18), PCI-1964, PCI-X and PCI Express. To do this, the board uses a set of transient circuits (active chipset). Such fees are called "active backplane", as opposed to passive, having on board only passive elements. As a computational kernel used board computers with bus expansion PICMG 1.0, PICMG 1.0 64-bit, PICMG 1.2, PICMG 1.3
