Appendix 2 - Preparing a Shielded Cable End
This section tells how to prepare the ends of the shielded cable. This process will be
repeated four times, at both ends of both input cables (although the cables will have
different overall lengths).
1.
Cut the shielded cable to the overall required length.
2.
Use a utility knife with a new, sharp blade to cut the plastic jacket of the shielded
cable 1” back from the end. Hold the blade perpendicular to the cable, and draw it
across the cable lightly as you rotate the cable along its long dimension. This
creates a scored line through the plastic jacket. With a sharp blade, not much
pressure is needed. You may need a bit of practice to get the feel.
3.
If you’ve scored the jacket carefully, you can separate the jacket at the score line
without using tools. Pull the insulating jacket off, exposing the cable, showing the
foil shield, the drain wire, and the fuzzy string. The result is shown here, with the
foil shield showing.
4.
Cut off the fuzzy string
5.
Separate and twist the drain wire.
