Apple Attachment Unit Interface (AAUI) A 14-position, 0.050-inch-spaced ribbon contact connector. Early Power Macintosh and Quadras had an AAUI (Apple Attachment Unit Interface) port (rectangular shaped) for Ethernet, which requires a transceiver. To use twisted pair cabling, you would need to get a twisted pair transceiver for the computer with an AAUI port. Some Power Macintosh computers had both an AAUI and RJ-45 port; you can use one or the other, but not both. The pin-out is: Pin Signal Name Signal Description ---- -------------- --------------------------------- 1 FN Pwr Power (+12V @ 2.1W or +5V @ 1.9W) 2 DI-A Data In circuit A 3 DI-B Data In circuit B 4 VCC Voltage Common 5 CI-A Control In circuit A 6 CI-B Control In circuit B 7 +5V +5 volts (from host) 8 +5V Secondary +5 volts (from host) 9 DO-A Data Out circuit A 10 DO-B Data Out circuit B 11 VCC Secondary Voltage Common 12 NC Reserved 13 NC Reserved 14 FN Pwr Secondary +12V @ 2.1W or +5V @ 1.9W Shell Protective Gnd Protective Ground AAUI signals have the same description, function, and electrical requirements as the AUI signals of the same name, as detailed in IEEE 802.3-1990 CSMA/CD Standard, section 7.

Apple Attachment Unit Interface (AAUI) is a 14-position, 0.050-inch-spaced ribbon contact connector. Early Power Macintosh and Quadras had an AAUI (Apple Attachment Unit Interface) port (rectangular shaped) for Ethernet, which requires a transceiver. To use twisted pair cabling, you would need to get a twisted pair transceiver for the computer with an AAUI port. Some Power Macintosh computers had both an AAUI and RJ-45 port; you can use one or the other, but not both.

The pin-out is:

AAUI signals have the same description, function, and electrical requirements as the AUI signals of the same name, as detailed in IEEE 802.3-1990 CSMA/CD Standard, section 7.
