POWER REQUIREMENTS
The Magnum Mini-Transceiver derives power directly from the AUI port on the
device to which it is connected. No external power supply is required.
WORKSTATION INSTALLATION
Magnum Mini-Transceivers attach directly to the AUI connector of the
workstation. Note the following table of pin assignments for the AUI
connector: Table 1: Pin Assignments for Ethernet Electrical Connectors
Pin Function Pin Function
1 Control in Circuit Shield 9 Control in Circuit B
2 Control in Circuit A 10 Data out Circuit B
3 Data out Circuit A 11 Data out Circuit shield
4 Data in Circuit Shield 12 Data in Circuit B
5 Data in Circuit A 13 Voltage Plus (+)
6 Voltage Common 14 Voltage Shield
7 Control out Circuit A 15 Control out Circuit B
8 Control out Circuit ShieldSHELL Protective Ground
(conductive shell)
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
10BASE-T Wiring Connection - Twisted Pair Segment
The following procedure describes how to connect a 10BASE-T twisted pair
segment to the Magnum TP1. The procedure is the same for both unshielded
and shielded twisted pair segments.
1) Using standard 10BASE-T media, insert either end of the cable with an
RJ-45 plug into the RJ-45 connector. Note that, even though the TP
connector is shielded, either unshielded or shielded 10BASE-T cables
and wiring may be used.
2) Connect the other end of the cable to the corresponding network
device.
3) When proper connection and power have been established, the TP1’s
LINK LED will illuminate GREEN.
BNC Connection - ThinNet Segment
The following procedure describes how to connect a ThinNet (10BASE2)
segment to a Magnum CT1.
1) Attach a ThinNet BNC “T” connector to the BNC connector of the CT1.
2) Attach the ThinNet cable to each side of the “T” connector.
3) Ensure that the ThinNet cable segment is terminated with a cable
terminator at both ends.
TROUBLESHOOTING
If difficulty is encountered during installation or operation, double check
instructions and specifications as mentioned on previous page. Also, verify the
following: 1) Cables/connectors: Check that they have been properly connected
-- wires & cables not crimped or impaired.
2) Power to unit: Use PWR LED to verify that unit is receiving
power
3) Problem isolated to Mini-Transceiver: Replace with a
known working device. Verify if the problem has been corrected.
If problem continues after completing all above steps, contact your supplier or
