E-TBT-MC04 10Base-T
Transceiver
• Stand-Alone model
• Attached Unit Interface (AUI) to
Ethernet RJ-45 connectors
• No external power requirement
The E-TBT-MC04 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 connector e
