5.2.7PM-RJ45 and RJ45U (Twisted Pair)

The PM-RJ45 card supports Ethernet twisted pair segments of any standard length. It is equipped with a single RJ-45 connector and an Auto/100 switch. The RJ-45 connector is shielded to minimize emissions and will allow both unshielded twisted pair (UTP) and shielded twisted pair (STP) cable connections. The Auto/100 switch is provided for user selection between operation in the auto-negotiation mode (Auto) or fixed-at-100Mb (100) with no auto-negotiation and no 10 Mbps.

The PM-RJ45U module is equipped with a Media Dependent Interface- Crossover (MDI-X) push switch to allow for cascaded connections. This feature eliminates the need for a special twisted

pair crossover cable.

The PM-RJ45 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 PM-RJ45 has ACTIVITY, LINK and SPEED LEDs.

The RJ-45 pins normally (TP crossover switch DOWN) are per the standard for hubs-to-users twisted pair wiring: 1 = receive+, 2 = receive-, 3 = transmit+, 6 = transmit-, other pins not used. When the TP crossover switch is UP, 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.
