AAUI Port

The IC693CMM321 Series 90-30 Ethernet Interface and the Series 90-30 CPU364 Embedded Ethernet Interface are equipped with an Apple Attachment Unit Interface (AAUI) port for connecting to the network. Compatible transceivers can be purchased that support 10Base5 and 10Base2 coaxial cables as well as twisted pair and fiber optic cables. The AAUI standard makes your selection of transceiver and trunk cable medium transparent to the Ethernet Interface.

Your network cables must meet the applicable IEEE 802.3 standards.

This section presents the information you need to specify the cables and related components required for Ethernet Communications, including AAUI port pinouts and cable diagrams.

Ethernet AAUI Port Pinouts

The AAUI port is a 14-pin D-type female connector. It is used to connect the Ethernet Interface to an external transceiver.
