We have a spaghetti tangle of various wires behind the hifi, which looks awful. So we decided to do something about it. Most of the wires can be simply replaced with shorter ones (hdmi, power, ethernet), but two of the ethernet/network cables come from another room on the other side of the house. One is a flat ethernet cable, one is a standard round one. The standard one wasn’t particularly well fixed to its plug, and the wire sheath was a bit short, exposing the inner wires.
So I decided to replace the ethernet RJ45 plug.
Well. What a to-do.
Luckily, there is tinterweb and YouTube, which helped enormously.
Inside each ethernet wire, whether it’s “Cat 5e” or “Cat 6”, are eight very small wires, twisted into four pairs. All different colours. They have to go into the tiny little RJ45 plug in the right order. But they are not twisted in the right colour order. Why not? you might well ask, but I have no idea. And of course the twisting leaves the tiny little wires curly, so they have to be straightened out, then sort of wangled into a flat row.
Long story short, I found the best way to manage it, having practised (a lot) on a spare standard Cat 5e cable, is the magic “pass-through” RJ45 plug. That means that you can leave plenty of length of stripped wires, push them all the way through, and then check they’re in the right order before you crimp them. Saves a lot of trouble, and many plugs. Also, once you’ve crimped and trimmed them, you can be more sure that it will all work. There are apparently crimpers which do the trimming, but my crimpers didn’t, so I just used a kitchen knife and sharpened it afterwards.
You can buy network cable testers and I guess it would be worth it if you’re going to do a lot of this. I’m not, just a couple here or there, so I tested mine on our laptop, plugging the spare cable, with new plugs on both ends, into the laptop and a switch box. Oh my, the glee when it worked!
So now I’m awaiting short HDMI cables, and we have a plan for the power wires, so it should start to look a lot better soon.
And here, to lighten things up a bit, is a photo of our lovely black elder with the pink flowers. It stinks, though, of tom cat. I don’t remember it being smelly in years past, so I’m assuming it’s actually a tom cat. Am currently spraying a diluted solution of white vinegar, each evening, round the base of the plant, and on the patio flags nearby. Today our cat won’t go out. I really hope it’s not because of the vinegar!
