Bus Architecture
The ISA backplanes allow the use of standard ISA
processors and option cards.
Printed Circuit Layers
The backplane is a four-layer .062" thick board. Two
signal layers, +5 voltage layer and ground layer.
Multi-layer construction provides excellent noise
immunity.
Bus Terminations
Terminations provide a method to prevent or minimize
reflections and interference on the bus. This can become
a significant factor on the ISA Bus with option cards
having non-standard load characteristics or with long ISA
Bus lengths. Installing terminations is required only as
needed by the customer’s applications.
Power Connectors
Power connection is through standard AT connectors or a
terminal block.
Auxiliary Power Connector
This connector provides additional power capacity for
power-intensive applications.
Keyboard Connector
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
