UTP AND THIN ETHERNET REPEATERS
• Connect 10BASE2 segment(s) directly to the Repeater as if each port is
a 50 ohm terminator. (Do not connect in the middle of a segment or
use a BNC “T” connector.)
• When a segment is properly attached and the far end of the segment is
properly terminated, the LEDs will cease alternating.
• Be sure to connect the shield of one (only one) of the segments to an
earth ground.
Each 10BASE2 port of the Repeaters acts like one terminator on the
10BASE2 segment to which it is connected. Therefore, each segment must
have one (and only one) additional terminator at the far end of the run. If
the terminator is not attached, or there are two or more terminators in
addition to the termination provided by the repeater, that segment of the
network will not operate properly.
Fig. 3-1. 10BASE2 Thin Ethernet Segment Must End at the
Repeater.
Some Network Interface Cards (NICs), hubs, and adapters have
terminators built in that may be enabled or disabled via jumpers. Make
sure that only the NIC at the end of the segment farthest from the
Repeater has its termination enabled and that all the rest are disabled. (If
an external terminator is used, then all the NICs should have their
termination disabled.)
