I bought some CAT6A to wire my home, Commscope 1091SD CMR-LP U/UTP cable, and bought Simply45 S45-1100 load bar type modular connectors to go with the cable, but for the life of me I cannot get my test tool to read anything but shorted pins with these modular connectors. Even a connector built and crimped with no wire inside reads shorted pins. I've made CAT6 cables with pass-through modular connectors just fine but I have had zero success rate with these load bar type connectors.
I have used an Ideal FT-45 Pass-through crimper on both my successful cat6 cable and unsuccessfully on this cat6a, and also borrowed a hardware store special southwire ratcheting crimper to see if it would do any better, ended up getting the same results.
Am I using the wrong crimpers or are my modular connectors somehow faulty?
Hello everyone,
I was looking for some advice, I don't really know a lot about all kinds of different connectors (not speaking exclusively about audio gear, also industrial etc.), and I'm looking for a really minimal way to create a modular cable, such as the ones in this posts:
https://www.reddit.com/r/DIYAudioCables/comments/c44t9v/finished_my_diy_modular_headphone_cable/
https://www.reddit.com/r/DIYAudioCables/comments/kgzizc/modular_balanced_cable/
So I wanted to ask what would be the shortest and lightest set of connectors, with 4 pin/5 pins (balanced+shielding), to use, I wanted to avoid using mini XLRs due to the length, maybe there's some kind of easily available connectors (possibly screw on ones), hope someone can help me out, just wanna avoid having 21321 adapters always hanging out of my Amps HAHAHAH
Wish everyone a nice day
My son is 12 and fascinated with home networking. I have shared some content from this sub with him. He is using our house as a learning lab and just posted his first video on terminating Cat5e cables and is working on a video on setting up a WiFi mesh network. I’m not sure if posting a link to his channel violates any rules of this sub but please check it out if you get a chance.

Hi --- I have 2 seasonic psu. After moving around I could not find the extra connectors for my PSU. Are all seasonic modular interchangeable?
PSU 1 Seasonic PRIME TX-1000 (lost my extra cables)
PSU 2 SEASONIC FOCUS+ 650W 80+G FM ATX (have package of cables)
can the focus cable used for PRIME TX?

I am designing a prototype for a modular USB-based system of modular HIDs (midi devices for the time being) where each module can serve as a standalone USB device or can be docked to one of the four sides of another module (preferably no matter the orientation, i.e. rotated 0, 90, 180, 270° ) . The smallest modules will be around 10x10cm (or 4x4") in size , with some larger modules possible (with edge lengths as integer multiples of the smallest module sizes) . Total setup size for most use cases would be around 50x50cm (20x20") or smaller, with up to 25 modules in most cases, although ideally the system would support setups of up to around 300x100cm with module counts in the 100-300 range. Additionally, if possible, modules connected to a USB host would act as main devices and auto-detect other sub-modules attached to its sides as well as their orientation.
Power supply would be USB-bus powered 5V for most setups, I'd like to have it rated for 2 or 3A. Some modules may need higher voltages, ideally I'd like to make use of USB C PD and have that rail specced to the full 20V 5A , but 12V 3-4A would be ok as well.
Communication between modules will probably happen via I2C and 2 more GPIO (one Tx, one Rx) per connector. I feel like these will help detect physical position and orientation of attached modules.
As far as connectors, so far I have come up with 2 symmetrical 6-pin pinouts , one for power, one for signals. The idea was to try if a combination of magnets and female pogo pin connectors (basically, just elevated pads sticking out from the PCB and enclosure) will be enough / will work at all. This was the pinout i came up with:
Rx SCL SDA SDA SCL Tx
12V GND 5V 5V GND 12V
The Tx/Rx lines will probably be low frequency, so i put these on the outside. The pins marked 12V are for the ~9-20V (12V nom.) higher voltage through PD (or worst case, a regular dc adapter).
My main questions are related to the communication bus and to connector choice and pinout. I figured I2C would be an ok choice for ease-of-use and because I don't expect to need huge amounts of data throughput
... keep reading on reddit ➡I'm asking because the online support for this isn't comprehensive or easy to understand at all. The pci cable from the psu has a 1 to 2 connector as in there is one plug psu end and the end that goes to the gpu has two 8 pins that split off, similar to how SATA cables have multiple plugs on one cable.
Or do I just use entirely separate cables for the 2 8pin plugs on the GPU?
My 3080 has arrived and it has three 8 pin connectors. I thought I had 3 8 pin pcie cable I’d cables but it’s actually two. Can I use my old split 8 pin and a modular one to make up the three connections or order another extra modular 8 pin?
So as you might understand I'm still trying to learn things here :). I'm about to build my first PC. Bought everything except for the PSU and the GPU. GPU because of hopefully the wonderful news that will be announced on the 31th of August (and me hoping I can order this straight away). But also holding of on purchasing a PSU because of those 12 pin rumors. Following the rumors and if the naming is correct I would be going for the 3080.
I've been trying to read about the answer but it feels like this is just very basic info that is not really being explained. So thought I'd just drop my question here so hopefully this wonderful community can just take away my doubts right away.
The PSU I was having my eyes on was the Corsair RMX Series, RM850x, 850 Watt, 80+ Gold. The rest of my build is a r7 3700x, x570 aoros elite, 2x16gb and 4 fans. The 850 watt definitely is overkill but I don't care spending a bit of extra money to be safe for the future for whatever I'd like to upgrade.
Thanks in advance y'all
