(4) Junction connector
This connector provides a connection between coaxial cables to increase the overall coaxial
cable length. In marked contrast to the repeater, which provides segment extension, the
junction connector increases the overall cable length for a single segment.
If two or more junction connectors are used at one time, the coaxial cable’s electrical resistance
may change (it is recommended that you avoid simultaneously using two or more junction
connectors).

(5) Terminator (terminating resistor)
When a bus-type wiring connection is made, the terminator is connected to both ends of a cable
to prevent signal reflections. The terminator connections must be made at all times. If the
terminator connections are not made, the network becomes inoperative due to signal reflections
(collisions). Two types of terminators are available: J and P types. The J type is used when a
tap-type transceiver is employed. The P type is used when a connector-type transceiver is
employed. Ensure that the terminator is positioned at the marking on a coaxial cable.
