The RPM-AUI connector supports standard IEEE signals, as follows:
Table 3.2.2: AUI Pin Assignments
Pin Function Pin Function
1 Control In Circuit Shield 10 Data Out Circuit B
2 Control In Circuit A 11 Data Out Circuit Shield
3 Data Out Circuit A 12 Data In Circuit B
4 Data In Circuit Shield 13 Voltage Plus (+)
5 Data In Circuit A 14 Voltage Shield
6 Voltage Common 15 Control Out Circuit B
7 Control Out Circuit A SHELL Protective Ground
8 Control Out Circuit Shield (conductive shell)
9 Control In Circuit B
NOTES:
1) Voltage Plus (pin #13) and Voltage Common (pin # 6) use a single
twisted pair in the AUI cable.
2) Pins 4, 8, 11 and 14 may be connected to pin #1.
4.2.3 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 Magnum RPM-DTE
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.
