Connecting to Twisted-pair Cable
The EtherLink III 10BASE-T adapters (3C509B-TP and
3C509B-TPO) are factory-set to use the on-board transceiver
with twisted-pair cable.
1 Make sure that the connector on your cable is wired
appropriately for standard 10BASE-T adapter cards.
Refer to Appendix A, "Specifications," for RJ-45 connector pin
assignments.
2 Align the RJ-45 plug on the end of the twisted-pair cable
with the notch on the adapter's connector and insert it
into the adapter socket.
The next step is to configure the adapter, as explained in
Chapter 3, "Configuring the Adapter."

Connecting to an External Transceiver

You can install AUl-equipped adapters and, by employing an
external transceiver, use either thin or thick coax or twisted-pair
cabling. Follow these steps to connect to an external transceiver:
1 Locate the adapter's AUI connector and move the slide
latch to the open position, as shown in Figure 2-2.
