Ethernet Attachment Unit Interface (AUI)

The ARN/DC Ethernet 10BASE-T base module, Ethernet expansion module, and

Ethernet/tri-serial expansion modules contain a 10BASE-T standard 802.3 AUI

DB-15 receptacle with a slide lock.

Table C-2

shows the pin assignments for the standard 15-pin AUI receptacle on

the ARN/DC base or expansion module and identifies its pin locations.

Note:

The AUI is designed only for connection to a transceiver. Connecting

the AUI directly to an AUI on an Ethernet station (without a transceiver)

violates IEEE 802.3 standards.
