CHAPTER 1
INTRODUCTION
The MR9T-C 10BASE-T/10BASE-2 Multiport Twisted Pair Repeater
(Figure 1-1) and the MR9T 10BASE-T Multiport Twisted Pair
Repeater (Figure 1-2) conform to all applicable IEEE 802.3
specifications. Each repeater has nine ports. Ports 1 through 8 on
both models are 10BASE-T compliant RJ-45 ports. Port 9 is where
the two repeater models differ. Port 9 on the MR9T has an RJ-45
connector. In addition, the MR9T has a special switch that alters the
pin configuration of Port 9. On the MR9T-C, Port 9 is a BNC
connector for a thin-coax connection. The MR9T-C also has a switch-
selectable internal 50 ohm terminator.
