this 9 year old video helped me so much to understand the cables thing. i have a lab test where we have to make this and we have never done it before. hope i dont screw up the crimping bc idk how much strength is needed for these tools in RJ45. Thank you so much for the video!
Crossover cables became a thing of the past 20 years ago. All computers, switches and equipment built in the last 20 years is able to identify and correct TX and RX on pins 1, 2, 3, and 6 so it doesn't matter at all. I prefer to wire in A because Blue and Orange are in the middle for phone.
Exactly the feature is called auto-mdix in Cisco switches !
Excellent. Very clear and easy to follow. I wish all instructional videos on RUclips would be this clear.
Thanks for your feedback.
Thank you so much! I'm glad to have watched this at such a young age, I'm told that learning all these is required in an electrical job. Thanks again.
Very helpful video, took me about 10 minuets to get all my connections done
just finished my straight through and crossover cables, both tested it on my cable tester and they both passed in flying colors. tnx for the vid instruction. jimi from the Phlippines.
Excellent to hear. Thanks for sharing!
For straight cable, the color order doesn't matter as long as it is the same on both end.
You make look simple and I think I finally got the hang of it. My advice to you is buy pre-cut assembled cables if you can because it ain't as easy as it seems. If you proceed do it on a day when you are at peace with yourself and have incredible patience. At the point when you are ready to push the wires into the connector make sure you see every wire in a straight line under your finger/thumb,all flat in a row and in the correct order. It is so easy for one wire to slip under/behind another and you are screwed. If I did this over again I would use pass through connectors. Murphy's law applies here and you will never succeed on the first try which is why you need lots of connectors. This job is a real bitch.
Very Nice narration with Clear view! Great job!
sorry, Just for clarification....using the 568A at one end and the 568B at the other end makes it a crossover cable just like you showed on your video? using 568A or 568B on both ends make it a straight through cable. am I correct? I appreciate your answer....thanks
+rhy Lasquite Yes that's correct.
yes u saying right so i agree with you
Thankyou now i know how to do the crossover in my school
Excellent Video, I did it my first try, I have the tools and the tester, I kept wasting connector after connector and couldn't figure out why the tester would not work, I finally looked up a video which was yours and realize my color platform was all wrong, I did a cable this morning with your color chart and the way you did it and the tester worked perfectly, Thanks alot.
John40ish Once you get a hang of it, then it's not too difficult. Glad you gave it a try.
John40ish It's great that you succeeded first try. I wish that the "whys" for doing straight through vs crossover would have been explained during the demonstration. For example, why flip colors? Not explained.
it's good to know how to make cable as an Network Technician
dial2fast....
If I use a "cross-over" coupler, I should be able to just terminate both ends of seperate cables as 568A and plug-in to the coupler (the cross-over would be performed by the coupler).... is this correct?
Thanks much
Thomas Crawford
Yes. As long as pairs 4 and 5 colors are reversed along the path, you're good.
If it helps imagine two people trying to talk to each other. It works best when one person puts their mouth ( the outgoing port) up to the ear (the receiving port). One pair sends communications and the other receives communications so they need to be "coupled" so the sender is sending to a receiving port and not another sending port that cannot hear anything.
This is the basic concept of a crossover cable.
Sweet vid mate, just made a cable run from 1 side of the house to the other following this guide, worked first try, GGez. Especially useful when he reminded everyone that the 1-8 is reversed when he flipped the connector over so noone missed that detail.
Thank you for your video regarding How to make Ethernet Cable RJ45-Straight Cable & Cross Cable
Awesome!! You explained something so alien-like (to me, anyhow) thoroughly and well. It's great that videos like this exist on YT. Noice!
Thank you for your comment!
The Best Vedio.. ever explained to very biggners
Studying for a Network+ and is crazy helpful so thank you very much !
Good luck with your study!
IDK but aside from T568B of A, I have been using non-standard color coding when setting up LAN ang it's working well. I just made it sure that whatever the color combination on one end is also the same on the other end. Is there a special feature with the copper wire inside a Wh-Or, Or and the Wh-Gr, Gr plastic cover with regards to Transmit and Received function?
i don't get it why there are people that disliked this useful video
Surely they are both wired exactly the same, just with different colours?
I had that uneven crimping experience too...looking head on it was like a hump back bridge, I noticed straight away...and was scratching my head...though in my case the connections were made enough to be reliable??? didn't have another tool on site to redo.. It was a ratcheting crimper also, never found the cause. just chucked the tool.
Perfect I kept wondering how do i remember the color order ever since i took the network plus exam
We did this in school. Our class wasted 200 of those RJ-45s
They're not wasted.They are reusable.
@@kellyash45 not if you crimp the wrong wire in the wrong pin. They dont just come out. You have to either cut the wire at the base of the terminal or crush the terminal itself and take the wires out.
How did you waste 200
💀💀
no way _💀_
i have a straight through cable in my house that has: WO/O/WG/WB/B/G/WB/B on both ends... so they messed up the blue and white blue's position, to my surprise it works fine though.. How is that even possible? I guess it doesnt really matter wich order you use them then as long as 2 sides are the same?
If wire color match on both sides, the cable will work, but the standard is designed to have specific wire in a specific pin position to minimize noise. This is why they use twisted pair instead of untwisted.
Good job. Straight forward. No BS. Looks idiot-proof.
Thanks for your comment!
thanks for this video, a such a very easy and clear how to make both types of cable, specially when you said remember the colour and just flip the green with orange .. learnt. and confusion removed, good Job
Glad my video was helpful to you!! Thanks for your comment!
Very thorough and informative. It would be beneficial though to know when you would want to use a straight or crossover connection.
Rick Regazzi crossover is for computer to computer or networking equipment that is similar ( majority of people would do straight through)
great video. The explanation is easy to understand. The advises are really helpful too. Thankss
Do you need to strip the end of the wires? Or does it make any difference?
Thanks too much, you really have helped me to terminate a crossover cable ....soo good well done & keep up. kindly what a bout straight through cable?
Helpful! Will be trying this out this coming Monday
I connected using only EIA 568B. Is this ok?
Many thanks man ! you just had me cleared from confusions about making of crossover cable.......
Glad my video was helpful.
Eether .
Ether
Man thanks😢😢😢😢
in making crossover..... do they have the same color combination in both ends?
your explanation is perfect, thank you
So it won't work if I just randomly ordered the wires but kept the same random order at both ends? I connected a head to a wire with a random order but repeated the same order at the other end and it didn't work. So the wires HAVE to be in that particular order?
The wires need to be in a specific order because there are Tx and Rx lines and the twisted pairs are put in a specific order to reduce EMI interference.
Thanks for explaining that for me... it was very easy to follow... and the cable pin up was a big help as well
Thanks for your comment!
What is the difference between straight through and crossover? would both work for internet connectivity?
you're the man ! you just had me cleared from confusions about making of crossover cables.
I have a Line 6 Spider 4 Guitar Amp 75watts - (non tube). It connects to a floorboard foot control via RJ45, the floorboard is powered through this connection. I would like to be able to "split" the cable somehow to connect one pedal board into 2 Amps. (Identical amps). But I don't want to blow anything up...
Any help would be awesome. Many people in Guitar Forums are wondering the same. The manufacturer offers 0 advise of course.
Thank you
Use an ethernet hub?
Angry Dergon
thank you, I'll check that out.
I know this is 2 years old but I'll give my advice anyway on this unique application.
I've never seen this application but if it's possible to split the pairs, as you can do in fast ethernet applications, which is what you might have for a guitar amp/floorboard connection transferring a small amount of data, you would make a "split, straight through cable", meaning you split the pairs but use a "straight through" pin out using two pairs for each connector and I'd label the cables near the mod ends "Amp 1" and "Amp 2".
The orange and green pairs would be used for one mod end "Amp 1" and the other two, the blue and brown pairs would be used for the other mod end "Amp 2", thereby "splitting" your cable. Both ends would be terminated with the same pin out.
Your orange and green pairs (O/W, W, G/W, G) land on pins 3, 4, 5 and 6 on one connector. Which color you put where does not matter as long as both ends are terminated the same, although you do want to make sure that only one color pair occupies pins 4 and 5 and pins 3 and 6 are occupied by the other color pair with the white wire landing on pin 3 so your pin out for the two mod ends of "Amp 1" will look like this on pins 3-6: W/O (pin 3), G (pin 4), W/G (pin 5), O (pin 6).
The other mod end pin out would use the Blue (B) and Brown (Br) pairs in the same fashion as above for a pin out on "Amp 2" cable and will look like this: W/Br (pin 3), B (pin 4), W/B (pin 5), Br (pin 6).
Let me know if you see this and try it and if it works for you in this application. Thanks!
What is the most important steps that should not miss?
very much helpful vedio for my pratical exam.. thanks man..
I am wondering if 100base TX uses only 4 wires, will cutting off the unused blue and brown pairs affect the speed? I am planning to cut them off on both ends for power delivery.
Wonderful tutorial, Sir. From Shashamanne, Ethiopia
+Joseph Jacob Happy to have helped!
working baby !thank you !
excellent 👍,,, atleast have understood
keep up the good work
I have a cat 5 cable, I use it to connect a wire from my router to a PC in another room. when I am working on equipment. like building PC's. for that cable, I would create just a Straight through, Right? What is exactly a cross over used for? I am thinking different type of equipment.
+Scott Castille Crossover cable is used for similar devices. Like switch to switch, or router to pc(similar in the way they send data). A straight through cable is used for dissimilar devices like pc to switch. and router to switch. If the router you are talking about that you are connecting your pc to is what typically gets provided by the ISP you are actually connecting it to a switch. Most home routers just have a 4 or 5 pin switch built into the modem. In that case since its pc to switch it would be a straight-through cable.
Hello,
My Question is that, Is it 568A Straight through or Cross over? Please let me know.
Thank you so much in advance.
Who else here from Mr V class , shoutout to yall
I'm trying to do this myself as professionals want £100 to fit the cable. The thing is as soon as I let the wire go when pushing the wires into the plastic end they cross over, so the wires aren't in line with the correct pin. It's very frustrating lol.
+Wes It does take practice, but you need to use your fingers to pull and straighten out each wire before lining them up. Move them around if you need to so each wire is not wrapped around another. Once you know they are straight and in order, then you cut to length and insert it (while still holding it down).
+dial2fast Okay, I'll give it another go. Thanks :)
This is one of the MANY reasons we get paid what we get paid. We have spent decades, usually, developing the education and skillset to be able to do what you cannot.
Pay the man and thank him for his expertise and give him the respect he deserves and stop being a cheap skate whiner.
My struggle is that the wire order becomes uncrossed when I insert the cable into the plug.
Very helpful video. Q: When would I use a straight-through vs. a cross-over cable?
Used when you have two 'like' similar devices, you would use xover cable (ex: from one computer to another), but now a days, many devices auto sense and switches for you.
thanks for this video it helps me a lot for my final examination later.. like!! :-)
Awesome explanation
thanks for the wonderful lecture
great tutorial!! If making a LAN to LAN connection (router to router) do you use a straight-thru or crossover cable? Thanks !
Group A: Router - Host
Group B: Switch - Hub
When connecting two elements from the same group use cross-over, otherwise if you're connecting 2 elements from 2 different groups use straight through
Great lesson. Thank you.
Thank you for video where can i download that great wiring cheat sheet
Hello Dial2fast, how do I pin up to match the keystone jack connections with the rg45 plug connections?
I just wired my home with ethernet cables, but now I need to make connections for the keystone plates on the wall and then rg45 plugs to connect to the keystones. do I pin up all the keystone connectors all the same configuration, and the rg45 in a straight or cross configuration won't matter??? thanks in advance for your help
From your switch all the way to your RJ45 wall plate, you wire it up straight through. So each connection will have the same color code and pinout.
Thanks for sharing, i just made my first crimp by using your video.. I am a beginner in the industry any recommendations or videos for installs ? thanks again
This help me a lot, wow! i did mine to. Much thanks.
Hi , what's the process for poe, cat5 cat6
When would you use a crossover set up or a straight set up ?
Thanks
Cross Cable for Similar devices and Straight Cable for different devices
❤❤❤Thank you...great
An excellent video! Good teacher!
Thanks for your comment!
Which color is mainly the data receiver?
I know that brown is mainly the data sender.
Actually, unless you are using gigabit, the blue and brown pairs are unused, on regular 10/100 Base T networks pins 1 and 2 (Orange for B Green for A) are used for transmit (TX) or upload and pins 3 and 6 (Green for B Orange for A) are used for receive (RX) or download
Here is a diagram for what all the pins are used for (Note: I may have polarity (pos/neg) backwards, and the unused pairs, while unused, are considered as ground (GND)
T568A T568B
1. TX+ White-Green White-Orange
2. TX- Green Orange
3. RX+ White-Orange White-Green
4. GND Blue Blue
5. GND White-Blue White-Blue
6. RX- Orange Green
7. GND White-Brown White-Brown
8. GND Brown Brown

Thanks for your comment.
is this the same for cat6

thank you. it helped a lot.
For a straight thru cable, does the sequence really matter? As long as it's the same on both ends then it shouldn't matter, correct?
If you simply match up both sides, the cable will most likely work. However you should learn the industry standard so you make the cable properly. I made a similar mistake when I first started in the industry, and the customer I was doing work for made me cut all the ends off and recrimp about 100+ connectors. If you want to be treated as a professional, then your work need to reflect that.
I think the reason for color code is to help eliminate distortion due to the corona created by the signal. Otherwise you might end up needing shielded cable.
The reason for the color code is so then when a tech replaces an end he doesn't have to hunt down the opposite end and color match. (imagine in a multi-floor office how tedious it would be so have to run to the bottom floor, write down the color order of 1 cable then go to the top floor to make the end, then back down for the next wire. Not to mention even trying to figure out which end is the other end when you have 100's of wires all coming out of one conduit)
Viper90087 Why the crossover of the twisted pair on pin 3 and pin 6 then? It'd be much easier to make the end if I could just do the color and it's white brother all the way, then just make the code: orange, WO, green, WG, blue, WBlue, brown, WBrown or something.
That was just a reason I came up with to get my guys to do it right, because I couldn't fathom doing it this way for no reason.
I'm an electrician btw, and almost all commercial lighting is requiring CAT5 now, so it probably doesn't really matter for me, but you're right, it is aggravating to change out an obvious bad end, just to find out that now you have to remake the other end, because they used a different color code.
I probably should have added that you were correct as well habib levi.the color code is also in part to prevent signal loss, cross talk, distortion etc..The other part of it is the pinning for networking 1,2 is transmit and 3,6 is receive. That's why they are not paired color, Wcolor all the way through, because of that receive pinning.Blame the idiot that invented routers and what not.would have been much simpler to just swap pins in the device where needed rather than require 2 different types of cables.Imagine if every electrical appliance like your toaster and coffee maker used a standard 3-prong removable plug, then were varied as to which side of the plug was positive, negative and ground. So then you'd have to buy a normal or crossover plug depending on how they connected the positive and negative inside the appliance.That's how big of idiots smart people can be sometimes.Routers, switches and what not have been around for how many years??? They still haven't changed it, because then they would have to admit to a mistake. So instead they spent 4x as much research designing switches that cost more which can automatically switch pinning. Maybe it was just some jackass's joke to annoy the world.
Wow artist
i enjoyed the video..thanks
Great video
Thanks for going to the trouble
awesome ... thank u
How much utp cable bro?
Awesome
Straight Through & Crossover, witch is faster?
Neither are faster. They are the same.
may issue ako about sa modem B525 using smart corpo ko to smart switch tapos kumonect sa switch 10 pc sa computer shop ko at isa sa kabilang bahay tru lan cable papuntang router nila always nawawa net nagkala kulay yellow triangle sa internet icon sa ng mga PC ko if bununutin ko connection ng kabilang bahay na kumonect sa TP link swith ko at ibalik after 5-10 seconds bumabik na connection nawawala na ang yellow triangle sa icon mg internet sa mga PC ko sa shop ko, ano kaya probs? salamat sa maka sagot
Annoyingly I'm trying to crimp some cat5 for poe cctv cams and there are only 6 cables. Black, red, green, green/white, orange and orange/white. Is this something for cctv cables as this cat5 cable came with the cameras. Can't find any reference to this wiring diagram anywhere, nobody referenced black and red cables. Some of the pins have to be empty cos there are 8 slots, so which ones are supposed to be empty? lol.
6 conductor is not an Ethernet cable. The company that made those probably thought since they only need a few conductors to work with the cameras, and to save cost, they are using a 6 conductor twisted pair cable. Doing it this way, you have no idea which pin goes where because it's a non-standard custom wiring. You can perhaps try to match the color on the existing RJ45 connector that came with the camera system.
@@dial2fast hey thanks for replying. I'm going to match it with the other end of the cable when I can get access to it.
isn't EIA/TIA 568B more common nowadays?
thank you.
what wire strippers are you using
You can check out this crimper set: amzn.to/2mfzhjJ
think you
Thanks
the top is Crossover and the bottom is Straight Through
Applying both at different ends of a wire makes the wire a cross over. If the ends are the same... it's straight through
