I have a friend who can do data connections in his sleep. He’s Asian, though, so he has the right genes. For the rest of us, how do you make those connections without copious amounts of profanity and throwing things at the wall?
I'm white and can punch down just fine.

The only reason to do it is if there's no good place for a jack and patch cord.



Lighting control panels with ethernet connections on the controller inside - I put a jack outside and run a patch cord to the controller inside. This way if someone (like me) is servicing the network there's no issue opening the panel, you can do what you need to do from that jack. If you need to test the controller, you can plug that patch cord directly into your laptop. No need to shut the lights in the middle of the day.



For time clocks, putting the jack on the wall is a bad idea, people like to tamper with time clocks. Many brands there's room inside the time clock housing for a jack and 1' patch cord, if not, terminate with a plug. Similar for cameras.

I'm not talking about a lighting panel, I'm talking about distributed room controllers, where there's a controller in the ceiling of each room, and the sensors and switches are daisy chained with Cat5 to that controller, as well as the controllers being daisy chained with one another. I could see putting jacks at the room controller end, but the sensors and switches it's easier to terminate male plugs at the device.

That makes sense to me. If it's what I'm thinking those are not ethernet devices, those are RS-485 and totally different rules apply.

I trained my 32 yr old son to install the male jacks about seven years ago.
He gets it right every time. Needless to say, his eyes are better than mine.

Taught my kids when they were young. Told them i was to tight to buy all the cables for there game systems so they either made there own or
went with out.

They enjoyed it and would fight over who got to make a cable then bet on the results of the tester. It probably cost me hundreds of wasted ends but it kept them amused.

Use flush cutters. The steps are pretty simple.


1. Strip back a few inches of wire.
2. Untwist all pairs
3. Get your wires lined up in the color order (Typically OW-O-GW-B-BW-G-BrW-B)
4. This is the trick. Match your thumb up with the spot where the sheath has been trimmed back. Press it against your forefinger and let it hold these wires in place. You will trim right at the edge of your thumb. This keeps the wires straight, gives you a spot to cut that isn't too long so that the RJ-45 can't get a good crimp on the cable jacket.
5. Trim the cable with FLUSH CUTTERS or LINESMEN. Diagonal cutters give you just that and make it hard to get your wires in the hole.
6. Check, check and check again.
7. Insert into crimpers, and give it a good solid push prior to crimping.



Bonus: The wire is cheap. Leave yourself plenty of slack so it isn't an issue to rework. The exception here being on large data racks.


That is all just for male connectors, though, and not jacks. I'm a fan of the tool-less jacks myself.
