Figure C.12: The characteristic of the cable
•  The characteristic of the cable Don’t strip off too much insulation for 
soldering. This could change the effectiveness of the Shielded-Twisted-
Pair cable and open a path to introduce unwanted noise.
Figure C.13: System Shielding (1)
•  Shield connection (1) 
If you break into a cable, you might get in a hurry to achieve your goal. 
As in all electronic circuits, a signal will use the path of least resis- tance. 
If we make a poor connection between these two cables we will make a 
poor path for the signal. The noise will try to find another path for easier 
flow.
