The RPM-AUI is equipped with a 15 pin female AUI connector and a slide- lock, and performs full IEEE 802.3 repeater functionality. It is used to provide connectivity with a 10BASE5

(ThickNet) backbone or to any AUI segments. A transceiver is required when connecting to a ThickNet

segment and the RPM-AUI supports this convention. The RPM-AUI is also a "universal" Ethernet media

interface as it may be used with a variety of different mini-transceivers

to provide connectivity to any media type. The Magnum RPM-AUI card is also used for connecting Ethernet devices using standard AUI cabling. In this situation, it is important to consider the AUI segment length or distance to the attached device (see details below). RPM-AUI cards are equipped with Partition (PART) and Receive (RX) LEDs which function the same as the identical LEDs on the RPM-BNC (see above).

NOTE: When the RPM-AUI is factory configured as a bonus port, it is implemented as an AUI connector with a ribbon cable to special pins on the main board. The functionality of this is identical to the RPM-AUI.

The maximum transmission distance between a backbone transceiver equipped with an AUI connector and an RPM-AUI port will vary. When an AUI cable is used to connect the Magnum RPM-AUI directly to a backbone transceiver, the maximum AUI segment length is allowed. If the RPM-AUI is connected to a transceiver that has been cascaded from another transceiver, the maximum AUI segment length is reduced.

According to Ethernet standards, the maximum distance from the transceiver AUI connector and the attached device (Magnum RPM-AUI) is 50m (165 ft.). The AUI segment maximum length is reduced in cascaded configurations. See the following note.

Important Note: The maximum transmission distance is decreased by 6m (20 ft.) for every additional level of network transceiver device "dropped" or "cascaded" from the original backbone transceiver tap.
