Twisted-Pair Cable and Pin Assignments
Caution: DO NOT plug a phone jack connector into any RJ-45
port. Use only twisted-pair cables with RJ-45 connectors
that conform with FCC standards.
The RJ-45 port on the EZ Card 1000 supports 1000, 100, and 10
Mbps Ethernet operation, with auto-negotiation of speed and flow
control.
Caution: Each wire pair must be attached to the RJ-45 connectors
in a specific orientation.
Figure B-1 illustrates how the pins on the RJ-45 connector are
numbered. Be sure to hold the connectors in the same orientation
when attaching the wires to the pins.
