Computer networks use a modular plug specifically designed for Cat5 (Category 5) cable. The modular plug, which is slightly larger than a standard phone plug, plugs into a female modular jack wired back to the network. The Cat5 cable has four twisted-wire pairs for a total of eight wires that must be connected correctly in series for the jack to function. Inserting these wires in the correct order into the jack and mounting the jack in the wall will have your network project wrapped up. The Philips RJ45 jack is similar to various industry standard RJ45 jacks in size; however, wiring may differ pending your application.
Pull about 8 inches of the cable out of the network box in the wall. Strip 3 inches of the outer sheathing off using the wire strippers.
Separate the twisted wire pairs. Untwist each of the pair wires and straighten them out with your fingers to remove any kinks, bumps or bends in the wiring.
Line up the appropriate coloured wire to the labelled pin on the RJ45 jack. Punch the wire down into the slotted pin jack by laying the wire over the slot, lining up the punch tool on top of the wire, and pressing the wire down into the slotted pin jack as far as it will go. As the wire is punched or pushed down into the pin, the blades from the slotted pin will cut through the insulation and make contact with the wiring, forming the connection.
Each pin will be labelled with a colour code to match the wire. As an example, punch the solid orange wire to the solid orange labelled pin.
Punch each of the eight wires into their correctly labelled pin until the Cat5 cable is completely wired to the jack. Use a cable punch tool if the Philips RJ45 jack pack does not contain one.
Snap the end of the RJ45 jack into the back of the face plate. Push the wiring into the network cable box and line up the holes on the plate with the holes in the box. Insert a screw into each hole and tighten them down with the screwdriver.
Plug in a male RJ45 connector, from a computer source, into the wall jack and test for a network signal.
It may be helpful to purchase a cable line tester to help check the connections and wiring on jacks to ensure they are properly connected. The tester could also help you troubleshoot any crossed wiring, depending on the model you purchase.
Avoid contact with the blades on the cutters as they can cause personal injury if care is not used during handling these tools.
