Upgrade Device

Sometimes when creating a data run you don't have the luxury to install face plates and Cat5 Cap stones for an inside run. You can still create an Ethernet point with a Cat5 surface mount telephone jack that you can mount on the outside of the wall without having to cut extra holes or having to run conduit.

This is generally done post construction for an extension of the central demarcation point for anything such as a T1 smart jack, cable modem, patch panel, switch, or router.

First you have to use a standard straight through cable from the demarcation point. The pin out of this has been mentioned before, but I'll show it again here to save some time:

RJ-45 Cat5e Standard Straight Through Pin Out:
Make sure the clip end is facing down and the pins will go from left to right Pin 1 - Pin 8. The gold leads in this picture should be facing you.

This will be the business end for the cable that will plug into the smart jack or whatever you are starting the run from. The other end of this cable will be wired up in the Telephone Jack.

The first picture of the jack is the common color layout of a Cat5 Telephone jack yours could be different depending on the manufacturer. What is really important is what is shown in the second picture. That is what you want your end product to look like:

Cat5 Telephone Jack (Before):






COLORS VARY BASED ON MANUFACTURER

The top end of this jack is where the Ethernet cable will plug into to connecting the demarcation point to the end device.









Cat5 Telephone Jack (After):





This is the pin out for how it should be connected.

So if using the colors from the picture above you would connect your Orange/White wire to the Blue wired pin and so on.











Once you have completed connecting all the wires together you should test for continuity with a LAN tracker before mounting and closing up the biscuit to save yourself some time and heartache if anything should not work out correctly.

This picture came to me in an installation guide that I thought would be nice to share with others and to have it when I am out on sites and do not have a reliable picture or book to verify my information.

This picture also gives a real life representation of the pin count on a RJ-45 end.
