3.1.5 75 Ohm Terminating Load
The Remote I/O system must be terminated with 75 ohm terminating
loads (M/N 45C71) attached to the taps or adapters located at both
ends of the coaxial cable network. This minimizes the signal
reflections which could interfere with other signals being transmitted
on the network. The terminating load consists of a BNC plug
connector and an internal 75 ohm resistor. See figure 3.6.

3.1.6 BNC JackĆtoĆJack Adapter
The BNC jackĆtoĆjack inĆline splicing adapter is recommended for
making cable splices when the length of a cable must be extended
(i.e, when adding a new drop). See figure 3.7. See Appendix G for
the recommended part.
