AUI Port
The IC697CMM742 Series 90-70 Ethernet Interface (Type 2) is equipped with an AUI port for
connecting to the network. The IEEE 802.3 AUI (Attachment Unit Interface) is standard across a
variety of different physical media. Compatible transceivers can be purchased that support
10Base5 and 10Base2 coaxial cables as well as twisted pair and fiber optic cables. The standard
AUI makes your selection of transceiver and trunk cable medium transparent to the Ethernet
Interface.
Your 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 Attachment Unit Interface (AUI) port pinouts
and AUI cable diagrams.
Pinouts of the AUI Port
The AUI port is a 15-pin D-type female connector. It is used to connect the Ethernet Interface to
an external transceiver.
