Installing A ControlNet Cable System
Publication 1786-6.2.1 - April 1998
Connecting Cable Sections
Connect the cable sections to the tap’s BNC connectors.
Terminating Segments
The taps on the ends of the segment have only one cable connector
attached to them. This leaves an open, or unterminated, end on the
segment. Signals transmitted along the cable will reflect off these
unterminated ends and interfere with transmission.
To eliminate signal reflections from the ends of the segment,
you must attach a 75
Ω
terminator to the first and last taps on the
segment. The terms “first” and “last” refer to the physical location of
the node along the trunk cable.
1.
Connect one end of the trunk-cable section to one of the tap’s
BNC connectors.
2.
Install a 75
Ω
terminator onto the tap’s other BNC connector.
