Ethernet Connectors and Pinouts
The Condor supports both the AUI and 10BaseT versions of the Ethernet 802.3 specification. The card will have a 15
pin "D" connector used for the AUI signals and a RJ45 connector for unshielded twisted pair (10BaseT). Transform-
ers are used with both interfaces to isolate the external cable from the interface electronics.
The single-channel daughter card is manufactured with both of connectors. The connector used by the channel is
automatically selected by the hardware when a cable is connected.
A dual-channel daughter card and dual channel motherboard are manufactured with only one type of connector for
each channel. For example, a dual channel AUI board will have two DB15 connectors. A dual channel 10BaseT board
will have two RJ45 connectors.
10BaseT Connector Signals
The 10BaseT signals and connector pinout for the RJ45 connector are shown in the following table.
