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). 

 

 

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.
