After you have determined the number of segments in your network,
multiply this number by two to determine how many terminators you
need for your network.
Determine What Type of
Connectors You Need Use the following table to determine what type of connectors you need.
IMPORTANT
To comply with intrinsic safety standards, be sure to
cover the exposed metal with the intrinsically-safe
insulator provided with each terminator.
Use This BNC Connector To Cat. No.
cable connector Attach trunk cable sections to a tap’s BNC connector 1786-BNC
Use This Optional BNC Connector To Cat. No.
Bullet (Jack-to-jack) Reserve a space in the trunk cable for future installation of a
tap or to splice a trunk cable 1786-BNCJ
Barrel (Plug-to-plug) Connect two adjacent taps without a trunk cable section
between them 1786-BNCP
Isolated-bulkhead
(Jack-to-jack) Go through grounded panel walls while maintaining the shield
isolation of the trunk cable 1786-BNCJI
Tap Terminator Cap off installed taps that have yet to be connected to a node 1797-TCAP
Right Angle
(Jack-to-plug) Provide a 90° bend in your cable (prevent bending your cable
excessively)
See Chapter 3 for the bend radius specification
