Teledyne LeCroy MINIPCI-3 - Manual

PCI Adapter Usage Guide
Catalyst adapters cards are designed with universal edge connectors so they can be used in both 3.3V
and 5V signal environments, therefore the edge fingers on the PCI side has keys in two different
locations. The two key locations on these adapters does not mean the adapter can be plugged in
the reverse direction.
The side of the adapter that has the connector and Catalyst Logo is the B side of the PCI bus, which is
called the component side. These adapters should always be plugged in to the motherboard with the B
side of the adapter matching the B side of the system. The diagram below may be used as a guide line
for indicating the B side of the PCI system.
