Hello, The "high speed hdmi with ethernet cable" I bought looks something like this: https://www.cmple.com/learn/hdmi-cables-28awg What I want to know is what are these very thick sections on this cable ? Looks like some kind of adapter/device is on this cable ? What is it ? What is it named ? What does it do ? (They look like two big fat round cylinders ?!?) Bye, Skybuck. ...

We make a bunch of boxes that go into a semi fab tool. One measures an optical waveform and shoots it to a bigger box, over three twisted pairs (clock, data, data) using shielded RJ45 ethernet type stuff. When we originally did it, they told us we were exempt from ROHS and EMI standards, but now we aren't. ROHS is no big deal, but the little box makes a continuous 62 MHz clock, differential...

I was looking up the wiring diagrams for Ethernet cables and found TIA/EIA 568A and TIA/EIA 568B wiring diagrams. They seem to be wired the same, but for the colors used. They swap green and orange. At first I thought I was looking at a crossover cable, but no, they clearly say they should be connected the same at each end. One uses orange and green pairs, while the other uses g

I did the following: 1. Replaced winfast motherboard with backup winfast motherboard. The backup motherboard is same model yet strangely enough missing one ethernet port, it only has one, while the other has two, also firewire pins missing but ok. 2. Put some new artic silver 5 on the cpu. 3. Struggled to get the scythe ninja heatsink on it, pulled it off then put it back on ? I know thi...

This is a common type of jack with integrated magnetics http://www.kosmodrom.com.ua/pdf/HR911105A.pdf It connects the txf centre taps via 75R resistors to a 1000pf cap which then (pin 8) goes to the circuit ground. What does this do? There are versions of the 10/100 jack which don't use the centre taps at all e.g. http://peter-ftp.co.uk/screenshots/20191119201261014.jpg

We need a 1-meter length of 100kHz (or slower) I2C onnection. It'd be nice to use a pre-made cable: micro-USB, 4-wire RJ11, or RJ45 ethernet. Some considerations: SCL and SDA crosstalk(?), high ground capacitance. Also need 3.3V, Gnd. Micro-USB: SCL and SDA twisted together, bad? RJ11: flat, SCL and SDA on outside lines? RJ45: SCL and SDA shielded from each other. -- Thanks, ...
