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.
2.3.4 RPM-FST (Fiber ST, Twist-lock Connector)
The Magnum RPM-FST is a multi-
mode fiber optic module equipped with a dual ST-
type connector. It functions as an IEEE 802.3 full
repeater to support 10BASE-FL and FOIRL
network segments. When used for 10BASE-FL
segments, this module supports fiber optic
transmission distances up to 2000m. For FOIRL
applications, it supports fiber segments of up to
1000m in length. The RPM-FST includes full Magnum RPM-FST
transceiver functionality and does not require an external transceiver device. In addition to
Partition (PART) and Receive (RX) LEDs, a LINK LED indicates connectivity.
NOTE: The RPM -FST circuit board contains a six pin jumper which controls the
intensity of the transmitted signal. By default, the jumper is placed across pins 1 & 2. The
jumper may be set as follows, to accommodate distances of up to 4 km:
