E-TBT-MC04

General Description

The E-TBT-MC04, IEEE802.3 compliant Ethernet transceiver uses 10Mbps Ethernet CSMA/CD protocol to provide a connection interface to 10Base-T Ethernet unshielded twisted-pair (UTP) cables. The transceiver connects to the AUI connector of an Ethernet device via standard AUI cable.

Connectors and Cables

E-TBT-MC04 AUI male connector

AUI D-sub 15-pin male connector accommodates AUI drop cables (50 meters max.). The AUI connector is used to connect the transceiver to the AUI port of an Ethernet device such as an Ethernet MAC controller, a repeater, or a hub via an AUI drop cable. The AUI connector is shown in Figure 4. The AUI male connector pin assignments are show in Table 1.
