When used for segments going to workstations and other user device connections, the switch

should be in the DOWN (or RIGHT) position. The LINK LED is particularly useful in

choosing the proper position for the up -link switch. If the LINK LED is illuminated, the

switch is set properly! If not, change the switch setting.

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. In addition to PART and RX (same as RPM -BNC, Section 2.3.1), the RPM -

TP has a LINK LED to indicate proper connectivity with the remote device.

Important Note: For the RPM -TPMDI-X Crossover Switch -

DOWN(or Right) for workstations and user connections.

UP (or Left) for Up -Link connections to other hubs, etc.

The RJ-45 pins normally (TP crossover switch DOWN or RIGHT) are per the standard for hub-to-user twisted pair wiring: 1 = receive+, 2 = receive-, 3 = transmit+, 6 = transmit -, other pins not used. When the TP crossover switch is UP or LEFT, the pins of the RJ-45 port are per the standard for up -links using twisted pair wiring, i.e., the transmit and the receive pairs are exchanged: 1 = transmit+, 2 = transmit-, 3 = receive+, 6 = receive-, other pins not used.
