LE180A 10Base-T Transceiver
• Stand-Alone model
• Attached Unit Interface (AUI) to
Ethernet RJ-45 connectors
No external power requirement
The LE180A transceiver is a media access unit
(MAU) that connects the AUI port of data
terminal equipment, repeaters, or other
network devices either directly or through an
AUI cable to an Ethernet 10BASE-T device. The Ethernet device is connected to the
transceiver through an unshielded or shielded twisted-pair copper cable with RJ-45
conne
