This is what you need to do to ground the shield of your cable. Take a piece of wire
and remove the insulation on both ends. Remove enough insulation on one end so you
can wrap several turns of the wire around the shield of the CAT-5 cable. Then use
some tape to hold the wire to the cable. The other end of the wire should goto one of
the ground terminals already connected up to the sensor. Either one of the three
ground terminal screws can be used. The ground terminal screw is the one nearest the
edge of the PC board. Looking at you picture, it looks like you have a blue wire
connected to ground on channel one. This is where you also want to connect up the new
Hope this helps.
