SEGMENTED BACKPLANE
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.
ISA SLOTS
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.
PCI LOCAL 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.
CPU SLOT
Each segment provides a CPU slot that
accepts a PCI Industrial Computer Manufacturers Group
(PICMG®) 1.0 compliant single board computer.
PRINTED CIRCUIT LAYERS
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.

terminal block connector. Power connection for +3.3V
is available through a 12-pin AT-style connector or
an ATX connector (optional).
AUXILIARY POWER CONNECTOR
Additional power capacity is available
through a 6-pin AT-style connector.
POWER INDICATORS
The power indicators provide a convenient
visual check for +5V, -5V, +12V, -12V and +3.3V power
connections.
KEYBOARD CONNECTORS
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
