Excellent. Good to know you’ve got it going.
I’m a little suspicious of that cable. It appears to be a telephone cable that’s been used (certainly it uses the standard colours for a 4-wire telephone cable: blue - orange - green - brown) and I think it’s got stranded conductors, which raises two questions: first: are the cable overall dimensions correct for the RJ45 that’s been used, and second: has the RJ45 got the correct insulation piercing tang for stranded conductors?
I question the first because I don’t think the cable clamp is doing its job, and the second because there are two sorts - one for solid conductors and one for stranded, and if the wrong one is used, it won’t be reliable. Done properly, IDC connections are good. Done wrongly, they’re very bad, and there’s no middle ground.
