Installing and Operating Passport ARN Routers
Ethernet Attachment Unit Interface (AUI)
The ARN 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.
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.
