Transition Networks - Media Converters, Extenders & NIDs

10Base-5 (AUI) dB-15 male [50 m/164 ft.] to 10Base-T (RJ-45) [100 m/328 ft.



The E-TBT-MC05 is an Attachment Unit Interface (AUI) transceiver that provides a method for connecting a workstation, or any other device with an AUI port, to twisted pair cabling in a 10Base-T network. Devices with AUI ports could include: servers, hubs, bridges and routers. The E-TBT-MC05 transceiver allows twisted pair, UTP or STP, to be connected to these AUI ports.


  • Provides a complete interface of the AUI to Ethernet UTP cable
  • Supports data transfer rate of 10 Mbps
  • CSMA/CD access mechanism
  • Capable of driving the UTP cable segment up to 100 m (328 ft.) without the use of a repeater
  • Selectable Link test and SQE test functions
  • AUI locking post design allows the E-TBT-MC05 to directly attach to a host’s AUI connector
  • Can be used with or without an AUI cable
  • LED indicators for network monitoring and diagnosing
  • The RJ-45 port will automatically detect and reverse the polarity on the receive pair, if needed
