RPM-DTE
The Magnum RPM-DTE is a module equipped with a 15-pin male DTE
connector with lock posts. (The RPM-
DTE is a mating connector for the
RPM- AUI which has a 15-pin female
connector and slide locks. The pin
assignments of
the two are the same). The RPM-DTE
card is designed to support direct
connections (no transceiver
required) using AUI drop cables to
any device that is equipped with an AUI port. Examples of such devices include servers,
router, bridges, hubs, and UNIX workstations.
