4.2.7 RPM-TP (Twisted Pair)
The Magnum RPM-TP card supports Ethernet twisted pair segments of any
standard length. It is equipped with a single RJ-45 connector. The RJ-45 connector is
shielded to minimize
emissions and will
allow both unshielded
twisted pair (UTP) and
shielded twisted pair
(STP) segment
connections.
Magnum RPM-TP
The RPM-TP module is also equipped with a Media Dependent
Interface-Crossover (MDI-X) slide switch to allow for cascaded connections. This
feature eliminates the need for a special twisted pair crossover cable.
With the switch in the UP position, the RPM-TP port is used for cascaded and
up-link connections (i.e.: a connection to another repeater or hub or concentrator
typically.) When used for segments going to workstations and other user device
connections, the MDI-X switch should be in the DOWN position.
The RPM-TP will support 10BASE-T unshielded twisted pair wiring (UTP)
environments with maximum segment distances up to 100m (325 ft.), or shielded twisted
pair wiring (STP) of 150m (500 ft.). This module is designed with internal transceiver
functionality. The RPM-FST has LINK, PART, and RX LEDs.
