Table 3.3.2: 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.
3.3.3 Connecting ThinNet 10BASE2 (BNC)
Connect the ThinNet coax cable to the BNC connector on the Magnum RPM-
BNC or BPM-BNC card in the same manner as is done for any standard BNC
connection. The PM-BNC port is specially equipped with an internal termination switch
on the front of the card (see Section 4.1 for a description of this switch). This eliminates
the need to use a "tee" connector when the BNC cable is ending at the connection to this
PM. Some applications may require a "tee" connector, used as a tap, to allow the
10BASE2 coax segment to continue on past the PM-BNC connection.
3.3.4 Connecting Drop Cable 10BASE5 (DTE)
Using the steps below as a guide, attach the 10BASE5 drop-cable directly to the
DTE connector on the RPM-DTE port.
1. Plug the female end of the cable into the male DTE connector on the RPM-DTE
card.
2. Engage the AUI connector slide lock (on the cable) to insure maximum
connectivity.
3. Connect the opposite end of the cable into a network AUI port. (This could be a
server, router, bridge, hub, or UNIX workstation.)
3.3.5 Connecting Fiber Optic 10BASE-FL and FOIRL (ST-type, “Twist-Lock")
The following procedure applies to FOIRL and 10BASE-FL applications using
an RPM-ST or BPM-ST card with ST-type fiber connectors. (The primary difference
between FOIRL and 10BASE-FL for users is the maximum distance allowed. 10BASE-
FL is used for a fiber segment length of up to 2000m, while FOIRL is used for fiber
segments of up to 1000m in length.)
1. Before connecting the fiber optic cable, remove the protective dust caps from the
tips of the connectors on the PM-ST. Save these dust caps for future use.
