Segment - Trunkline sections connected via taps with terminators at each

end; a segment does not include repeaters.

Tap - A component that connects products to the ControlNet trunkline cable.

A tap is required for each node and for both sides of each repeater.

Terminator - A 75-ohm resistor (mounted in a BNC plug) placed on the ends

of segments to prevent reflections from occurring at the ends of cables.
