Assembly Of A Category 5/5e Shielded Solid Or Stranded RJ45 Plug

Twisted pair cables such as CAT5, CAT5e, CAT6 and CAT6a cable are a low cost and easy installation alternative to traditional coax cables for transmitting KVM and AV signals. KVM (keyboard-video-mouse) extenders via CAT5 may be used to remove computers from harsh or sensitive environments, or to restrict physical access to the computer. Video extension products such as VGA, DVI, S-Video or HDTV extenders via CAT5 are used to extend video displays. Each extender consists of two units - the local and remote units, which are interconnected using a CAT5/5e/6 cable.

This article focuses on the proper method for terminating a CAT5/5e shielded solid or stranded cable using standard tools and materials that are readily available. With the proper use of the tools and a little practice you will be terminating CAT5/5e cables in no time.

Prepare the cable

You will first need CAT5/5e shielded cable (solid or stranded for the purposes of this article) cut to the desired length. The cable can be terminated before or after installation, even if you have a long run to make. Using a cable tester from VPI (www.vpi.us) the cable can be easily tested for continuity, crossed pairs and pinouts to make sure all connections have been made properly.

Next you will need to make sure you have the correct plugs to terminate the cable with. Different plugs are intended to different types of cable, whether you have solid or stranded connectors, flat or round cable, shielded or unshielded, and CAT5, 5e, 6, or 6a. Be sure to use a plug suitable for your cable.

For tools you need a CAT5 wire stripper, wire cutters, RJ45 crimp tool, and a CAT5 cable tester.

Terminate the cable

First, carefully strip the jacketing from the cable to expose 1" of the insulated wire conductors. Don't cut too deeply or you will knick the wire insulation underneath. If you just score the cable jacket and bend the wire in several directions to finish the break, the result will be a good problem-free cut.

Next, peel the foil shield insulation back onto the cable jacket and trim to within approximately ¼" of the jacket edge. Wrap the drain wire such that it is located at the bottom (locking-tab side) of the cable. Do not remove any insulation from the conductors.

Untwist the wires all the way to the jacket edge (but not beyond) and arrange them according to TIA/EIA 568A or 568B standards.

Carefully flatten the wires and align them for insertion into the plug. Make a straight cut across all wires to ensure the ends are of equal length, leaving approximately ½" of the wire sticking out from the jacket edge. The plug has small openings in it, one for each conductor. The wires must be placed in the proper order for either the TIA/EIA 568A or 568B standard.

Hold the RJ45 plug in front of you with the locking tab down, cable opening towards you. Orient the wires so connector pin 1 aligns with cable wire 1, pin 2 aligns with cable wire 2, etc. Pin 1 is on the far left with the plug held as described. Slide the wires into the RJ45 plug. The cable jacket should extend into the connector about 1/4" for strain relief and shielding connection. Make sure the drain wire is positioned at the bottom of the connector as this is where it will see the greatest contact with the shield of the RJ45 plug.

Using the RJ45 crimp tool, crimp the assembled termination to make it permanent. Firmly squeeze the handles to set the contacts and secure the plug. Once crimped, the termination should be tight and very difficult to remove.

Test the cable

Use the CAT5 cable tester to check your work. The tester will indicate proper continuity (complete connection end-to-end), make sure the pairs have been matched up properly, and that the pinout is according to the selected wire standard. If an end is wired incorrectly, the tester will indicate which end is incorrect. Simply cut off the end and try again.

Be sure to see more articles about CAT5 cable termination available from VPI. Other types of cable require slightly different procedures, so not all of the details for the cable you want to terminate will be covered in this article.

future technician - socket sizes?

I'm going to be a future technician soon.

Soon, my Snap-on tools listed below will arrive:

AUTO GRAD SET (METRIC & SAE)

- BRUSH, TERMINAL
- SET, SOCKET, METRIC, SHALLOW, 6-POINT (12 PCS.) (8 TO 19 MM)
- HAMMER, BALL PEEN, 16 OZ.
- CARBON SCRAPER, RIGID, BLACK, 7/8" BLADE WIDTH, 7 5/8"
- MIRROR, ROUND, 14" EXTENSION (MIRROR: 2 1/4" DIAMETER)
- BOX, METAL, 2 DRAWERS, REMOVABLE TOTE TRAY, 18.5" X 8.5" X 9.5"
- SET, WRENCH, METRIC, COMBINATION, 12 POINT (7 PCS.) 10-15 MM, 17 MM)
- 3 PC PLIERS SET
- WIRE STRIPPER/CUTTER, (AWG 10 TO 20), 6"
- TEL 2 LB PICK UP TOOL CHROME
- set, wrench, combination, 12 point (7 pcs) (3/8" to 3/4")
- set, general service, 6 point (10 pieces)

For the sockets, it has shallow.

Should I also a a set of deep sockets as well? SAE and metric, or just one? Are semi deep sockets good?

I need some advice.

If I do buy it, it's probably going to be Craftsman.

Best Advice
Get a locking tool chest and a heavy beastly chain and Thick Wire type of chain like an expensive
Get the best and easiest lock to use you can find.
Lock it up when your not in the shop
Just explain to people its a force of Habit you learned somewhere like the military or high school so they will not be offended your locking your stuff up.
Get the expensive snap on deep well sockets
and the cheap craftsman shallow well
The craftsman deep well sockets are constantly splitting on me.
Most of the new stuff is all metric. but I work on the old stuff so the metric stuff takes a back seat.
12 points basically suck they strip more bolt heads than the six.
Make sure you get a good set of torx screw drivers and sockets the smaller sizes at least.
you know the star shaped stuff torx or torqs however its spelled.

Get a good universal joint 3/8 you wouldn't believe how valuable these are to have and all different assortments of extensions and screw drivers of every different size.

You've got a good starter set just keep adding to it and you'll be set. You may want to get a cheap set of air tools to start with. at least an air ratchet. ant oil them before every use. A shot of WD 40 get a big ol can with a fold down straw. in the air inlet. I love the fold down straw I allways used to loose the damn straw.
2.5 double faced engine hammer or sledge for those micro adjustments or attitude adjustments.
