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 Satan to temp people to falsely blame the
people at Aptos and stir up strife on the reflector.
If the radio ever accidentally gets lifted or pulled by an RJ45 cable...
Heh, heh.
It's possible to have one of the wires in the cable break and have the rest
of the cable hold it together, with two broken ends touching each other,
whenever they feel like it. Very intermittent. When you move the rig to
find the trouble, the movement of the cord can re-touch the wires and the
trouble go away. As soon as you put it back trouble comes back.
You think I'm exaggerating or kidding? I'm not. Been there, done that, been
exasperated, gone round the bush multiple times trying to chase down a
@$*&^@&%$% intermittent trouble.
Treat them like they're cheep cr*p, because they all are. They were
DESIGNED to be cheep and do away with all that manually expensive cording
for phones and phone style connected devices. Larger stranded wires with
crimp screw eyes are much more durable, but cost a lot more. It's all about
money and easy to assemble at the factory, or dump it off on the installer
and don't pay for installation at all.
Never pull on them. Never drop anything on them. Never stretch/straighten
them out by holding the connectors. Never force an RJ45 into its socket if
it doesn't want to go. Find out what's wrong first. Never use them to
connect to something that is vibrating, or gets regular motion.
If anything involving an RJ45 cord doesn't work, rule out the RJ45 first.
Save yourself time and frustration.
There may be a pure, kind, likable, friendly, softhearted and honorable
RJ45 out there, that never caused anyone any trouble, that will suffer
prejudice on account of this. Poor thing will just have to deal with it.
His fambly has a terrible reputation.
73, Guy.
