Determining What Type
Of Connectors You Need
Use this BNC connector:
cable connector
Use this optional BNC connector:
bullet (jack-to-jack)
barrel (plug-to-plug)
isolated-bulkhead
(jack-to-jack)
tap dummy load
right angle (jack-to-plug)
In this example, ControlNet cable:
•
enters and exits the panel enclosure
from the side using
isolated-bulkhead connectors
•
contains two adjacent taps
connected by a barrel connector
•
reserves one future tap location
with a bullet connector
•
makes a sharp bend with a right
angle connector

To:
attach trunk-cable sections to a tap's BNC connector
To:
reserve a space in the trunk cable for future installation
of a tap or to splice a trunk cable
connect two adjacent taps without a trunk-cable section
between them
go through grounded panel walls while maintaining the
shield isolation of the trunk-cable.
cap off installed taps that have yet to be connected to a
node
provide a 90û bend in your cable (prevent bending your
cable excessively).
See Chapter 3 for the bend radius specification.
