Re: [Elecraft] K3S RJ-45 Pin Alignment

I find these connectors to be among the most reliable connectors I use. I use them for my home network, as well as various other places where manufacturer's have placed them (e.g. the IC706 mic connector in my 4Runner). The pigtail I use to connect my computer to the network is missing the

Re: [Elecraft] K3S RJ-45 Pin Alignment

Unfortunately it's not the plug that gets flogged by the wiggle wiggle wiggle... it's the socket. \Replacing the socket of a RJ45 in any piece of equipment that has been flogged to death is a little more than most Hams can cope with. The quality of the sockets that most manufacturers use is also

Re: [Elecraft] K3S RJ-45 Pin Alignment

Microphone connectors fail eventually, even the well-made ones with set screws and clamps. There is one advantage to the RJ-45 -- it's easy to clip off a little wire and crimp on a new one. Replacing a more traditional connector is much harder. 73 -- Lynn On 5/1/2016 9:35 PM, Edward R Cole

Re: [Elecraft] K3S RJ-45 Pin Alignment

I've seen so many uses that were not adhering to the standard 4-pair. But the most miserable use is as a mic connector which Motorola went to. Now I see many ham radio mfr's copying. Instead of molded multi-contact connector with set screw which holds contact tension its just wiggle wiggle

Re: [Elecraft] K3S RJ-45 Pin Alignment

There are 2 wiring standards for cat5/5e/6 cable into RJ45 style modular plugs: EIA/TIA-568A and EIA/TIA-568B (aka T568A and T568B). They are slightly different, and both work to gigabit speeds. You can mix them, but in a data center, for example, they will try to stick with 1 or the other. For

Re: [Elecraft] K3S RJ-45 Pin Alignment

Just to be more accurate the term RJ45 defines the wiring of a 4 pair twisted cable (like a CAT3, CAT4, CAT5, CAT6) to an 8 position, 8 contact modular plug. The plug and jack are described by the number of available contact positions and the number of contacts installed in those positions.

It is so easy to bust an RJ45 cable it really isn't funny. There are so many ways to screw up the connector it isn't funny. Never trust an RJ45 cable, it only works if you can prove it works. Otherwise it's something that Murphy has slipped into our usage to get even. Maybe something inspired by

Re: [Elecraft] K3S RJ-45 Pin Alignment

I agree with Don. Try a new cable. It doesn't take a lot of flex to break one of those small solid copper wires. If it's broken in the connector it wasn't crimped well, as the standard RJ-45 has a strain relief built in that clamps down on the cable to keep it from pulling out. I just

Re: [Elecraft] K3S RJ-45 Pin Alignment

"Click" is all we have to determine if it's seated, so I guess "Yes", that's all there is. I'd try another cable. My experience with RJ-45's is in large, tied bundles fanning out to a rack of routers or other devices. Nothing moves, it's all tied down. In single lots, RJ-45's leave a bit

Re: [Elecraft] K3S RJ-45 Pin Alignment

I use the RJ45 all the time now [P3]. Found that you have to make sure it is fully seated, and that the plastic spring-tab thingie has completely engaged (decompressed). I've heard that IT techs force them into the RJ45 socket, so it's not a problem isolated to the K3's RJ45. Otoh, IT

Re: [Elecraft] K3S RJ-45 Pin Alignment

Another thing it could be is a bad connector to cable connection. It can be intermittent. Another thing to look at is have any of the wires in the jack been bent. They are pretty flimsy. David K0LUM > On May 1, 2016, at 5:59 PM, Byron Peebles wrote: > > I have indeed done

I have indeed done all the clicks and boot removals and been unable to resolve the disconnect. It even happens when the radio is in-use and suddenly has the radio disconnect from the computer. So, the only answer is the standard "make certain it clicks", which it does? 73, Byron

Re: [Elecraft] K3S RJ-45 Pin Alignment

Some times the tab has been pressed down and does not spring up enough to lock properly. I prefer non hooded ends and lift up on the tab before inserting to bake sure it will click and lock properly. David K0LUM > On May 1, 2016, at 2:19 PM, Guy Olinger K2AV wrote: > > Hi

Re: [Elecraft] K3S RJ-45 Pin Alignment

Hi Byron, If an RJ45 cable does not make a "snap" sound upon insertion to the socket, it is not seated properly. Also, what happens very commonly, is that the little tab on the plug that locks the plug into the socket has been broken off. Again, VERY common for the tab to be broken off. An RJ45

Re: [Elecraft] K3S RJ-45 Pin Alignment

Byron, There is a latch on the RJ-45 plug - if the plug is inserted sufficiently, you will hear a slight click when it is fully inserted. Once latched, it will not fall out. You may have to move the boot back a bit and push on the plug assembly itself to get it to latch. Once latched,

I continue to be plagued with the radio disconnect azssociated with the RJ-45 interface on the K3S. Has anyone ever heard of an RJ-45 Pin Alignment tool? I suspect there is some physical issue that is not resolved by removing the boot and everything else that I've tried. Forget about it
