ePCI-101 User’s Guide
Upon a power-up or reset, the Parallel Port interface circuit is automatically configured for the
operation mode setup in the BIOS. This Parallel Port signal assignation on the connector depends
upon the operation mode (STD, EPP, or ECP) it has been set:
2.5 Ethernet Controllers (J12 and J14)
Two Intel 82551ER Ethernet controllers are used. These controllers support 10Base-T and 100Base-TX
operations: 10Mbps and 100Mbps network speeds are automatically detected and switched.
The 82551ER offers automatic crossover. When connecting an ePCI-101 to another computer, a
straight cable can be used and the 82551ER will automatically swap the TX and RX pairs.
Signal Paths:
J12 and J14 RJ45 connectors on the bracket.
