But there would be analog and digital signals in the same cable. Is this a problem ? It can be a problem depending on the nature of the signals, the type and length of the cable, and what's at either end. In other words, there are many variables. If so, what are the solution to transmit digital and analog signals at the same time ? Use cable that shields ...

On a first look It is a TRRS 3.5mm splitter. Being TRRS an abbreviation for tip, ring, ring and sleeve. But since your are going to use this in a headphone I think you will be better served with the results of a 3.5mm TRS splitter or stereo splitter search. TRRS will be hard to find because the existing cables split the audio from the mic and it seems to me ...

The end that appears closer in the picture is a 3.5mm TRRS (tip, ring, ring, sleeve) connector, while the other two connectors are both 3.5mm (most likely, it's hard to tell if they may be 2.5mm) TS (tip, sleeve). This means that if the cable is wired normally, the TRRS connector goes like this: Tip = Left Audio (The hot lead on one of the TS connectors) ...

That's microphone and headphone cable combined, having a TRRS 3.5mm audio jack of unspecified pinout, with 2.5mm mono audio jacks at the other end. There's no better name for it, and your picture sadly doesn't fully specify how the microphone and two stereo channels should be connected to the TRRS, which depends on the device you plug this into. So: "...

I can confirm that a miniDP cable is capable of what I intended to do. The only thing is, power should not be carried by pin 20, since in most (if not every) commercially available cables, it's an unconnected pin. So you have to choose another PIN to carry Power. At the moment I am using pin 2 and 19 (for redundancy) The setup works

You can shuffle conductors but: if you swap pair-for-pair, MDI-X auto-negotiation might unswap them on the fly. Someone will connect their laptop and it'll "just work". if you mix conductors between pairs and then run it over normally wired segment, you'll get crazy crosstalk that will probably kill the communication, receive lots of interference ...

(1) Cut the locking tabs on the plugs on the patch cables so they can't easily be removed from either end (2) Use a locking device eg http://www.rjlockdown.com/patchcordpage.html https://cpc.farnell.com/tuk/kpj2nt/t-lok-tamperproof-faceplate/dp/CS31332 https://patchsavesolutions.com/236-rj45-patch-cable-locks (3) Run a script on your VoIP server that if the ...

Oooh this is (not) fun. Didn't see it used for power transmission yet; As I see it, they attached an impedance meter between each of the ABCN (L1 L2 L3 N for us europeans) on the left and every other ABCN on the right, the recorded Z is put on the table. The matrix has to be symmetrical (otherwise the cable from a two port system view would be… interesting) ...

switch to using drivers and receivers to put the signals on the cable eg MAX3232: these are 25V tolerant, and I've accidentally connected them to USB ports without causing any damage to the USB port.

Cat6 is a standardised twisted pair cable for use in Ethernet and other networks. Source Fibresales Cat 6 patch cables are normally terminated in 8P8C modular connectors, using either T568A for horizontal cables or T568Bpin to match the older AT&T assignments. Source Wikipedia The only difference between these configurations is that pairs 2 and 3 (...

The purpose of a ferrite bead around a pair of cables is to balance the impedance of unbalanced signals like VGA signals and microphones and more over the spectrum that may cause interference. By raising the CM impedance the differential impedance remains constant while the percentage of imbalance is reduced. While not used on most HDMI cables they are ...
