The backplane is divided into two segments with
each segment operating independently and consisting of an ISA
Bus and a PCI Local Bus. The two segments share the same power
source.
Provides a total of five ISA Bus slots for the
use of standard ISA Bus option cards. One segment provides three
ISA Bus slots; the other provides two ISA Bus slots.
Provides a total of six PCI Local Bus slots
for the use of standard PCI Local Bus option cards. There are
three PCI slots in each segment.
Each segment provides a CPU slot that accepts
a PCI Industrial Computer Manufacturers Group (PICMG®) 2.0 compliant
single board computer.
The backplane is a six-layer .062" thick board.
Three signal layers, +5 voltage layer, +3.3 voltage layer and
ground layer. Multi-layer construction provides excellent noise
immunity. |
The standard AT power connection is available
through a 12-pin AT-style connector or one terminal block connector.
Power connection for +3.3V is available through a 12-pin AT-style
connector or an ATX connector (optional).
Additional power capacity is available through
a 6-pin AT-style connector.
The power indicators provide a convenient visual
check for +5V, -5V, +12V, -12V and +3.3V power connections.
Three keyboard connectors: two are 5-pin headers
and one is a standard AT 5-pin DIN connector. These connections
provide options for front or rear mounted keyboard connectors.
