Wiring RS-232C and RS-422 Cable Connectors
Prepare cables as follows before soldering:
1, 2, 3...
1. Cut the cable to the required length.
2. Thread the end of the cable through a boot at least 50 mm up the cable.
3. Being
careful not to
damage the braiding underneath, use a razor blade to
cut
away 25
mm of sheath for an RS-442 cable or 40 mm for an RS-232C
cable.
4. Using scissors, cut away all but 10 mm of the exposed braiding.
5. Using wire strippers, remove the covering from the last 5 mm of all wires.
6. Move
the boot to the
cut edge of the sheath and fold the braiding back over
the end of it.
7. Wrap
aluminum foil tape 1 1/2 turns over the top of the braiding on top of the
boot.
