SpeedyV Posted January 24, 2018 Share Posted January 24, 2018 Huh. Never tried it. Don't know if it will work but I doubt it would damage anything. If you do try it please do post your results. Google may turn up something. Link to comment Share on other sites More sharing options...

Google may turn up something. I decided to go ahead and test the parallel setup and yes, the strips synchronize successfully in parallel!! :biggrin: Now to see if you can chain parallel sections in serial on each channel.

dorbot Posted March 15, 2018 Share Posted March 15, 2018 (edited) I noticed these LED strips are directional. First time I got lucky, but the second strip didn't work at first because I was starting from the wrong end. The strips have arrows on them. Didn't see that mentioned anywhere before. I played around in SIV with 96 led strips but really 96 led strips are too long to be practical. I had some high density LEDs too and that was about the right length if using 96 LEDs but Corsair link 4 only addresses 40 which is about a foot long. So, I too am hoping Corsair allow more LEDs in firmware, so that high density strips are more practical. I like the parallel wiring mentioned above, but I think we need to watch the current draw. Is there a reachable current limit per channel? If we are powering our Node Pros or link Commander Pros via SATA?

Some of that is used for the MCU in the NoPro but exactly how much isn't exactly clear. It's pretty safe to be able to go up to 60 LEDs per connection (6 of the Corsair strips). Over that you start getting into dangerous territory. Link to comment Share on other sites More sharing options...
dorbot Posted March 15, 2018 Share Posted March 15, 2018 (edited) I think siv estimates the current in amps drawn per channel, but I don't know what the total limit is. Anyway, I've decided to use Link 4 for the LED's at the moment and to just use 40 per channel for now because frankly I'm struggling to fit it all in the case. I'll need to buy some more strips at VAST expense from China if I want to use Siv to control everything with 96 ( or more later I hope) led strips. I might put a long strip along both sides and the back of the desk or maybe 2 in opposite directions for the true pimp look. But my computer already looks like some kind of seedy neon brothel from a dystopian sci-fi future..... EDIT : 4.5 Amps is the SATA 5 Volt current limit apparently, correct me if I'm wrong.

But my computer already looks like some kind of seedy neon brothel from a dystopian sci-fi future..... EDIT : 4.5 Amps is the SATA 5 Volt current limit apparently, correct me if I'm wrong. Yes its 4.5 amps total for the Commander Pro. You can make your own cable so only ground and data come from the Commander Pro (or Lighting Node Pro). Take the 5VDC pin from the LEDs and tie it to a 5VDC ouptut from the system power supply. I have done this and it works. That way, the drive current is not flowing through the Commander Pro (or Lighting Node Pro). I have never tried putting stips in parallel so good to know that it works. I would not try doing it with more than 2 strips in parallel though. It might work... I only use SIV for control of my Link products. I have a total of 261 LEDs running in my rig - 159 under SIV control and 102 under Asus AURA control (plus the MOBO LEDs). I have 3 different Corsair fan types and 114 WS2812B LEDs divided into several strips. I have a Commander Pro, 2 Lighting Node Pros, and and LED hub for the fans. Those high density WS2812B strips do get awfully bright. I just cut one up into smaller sections and soldered connectors on the ends (which is kind of hard to do on those strips). It all works great though I do have some of the high density strips dialed back to 60% brightness due to current limitation concerns. I am pretty sure that Link could not control all of this the way SIV can. SIV can do everything Link does except the software playback for LL series fans. It can also do a lot of things Link cannot do, though there are other limitations imposed by the Commander Pro and Lighting Node Pro firmware that you just can't get around. Anyway, it's good to see people exploring, trying new things, and pushing the limits. If anyone is interested, I posted more details about this LED crazy rig here. http://forum.corsair.com/v3/showthread.php?t=174049 Have fun everyone! And watch those current limitations.

CrazyAngel1990 Posted November 2, 2018 Share Posted November 2, 2018 So if I understood correctly is it possible to connect any addressable led strip do I make the right connections? Link to comment Share on other sites More sharing options...
DevBiker Posted November 2, 2018 Share Posted November 2, 2018 So if I understood correctly is it possible to connect any addressable led strip do I make the right connections? Yes ... and as long as you keep the current limitations in mind. Link to comment Share on other sites More sharing options...
CrazyAngel1990 Posted November 2, 2018 Share Posted November 2, 2018 Yes ... and as long as you keep the current limitations in mind. What would be the limitations? Because I would like to put a strip across the desk so I can command it from the icue software but I would almost always keep it one color, would it be possible?

DevBiker Posted November 2, 2018 Share Posted November 2, 2018 It's limited to 4.5A overall; so little over 2.0A for each channel. And yes, that's certainly possible. Check out Zotty's setup in the RGB FAQ. Link to comment Share on other sites More sharing options...
CrazyAngel1990 Posted November 2, 2018 Share Posted November 2, 2018 I looked a bit and I did not understand very much, also because I do not Italian so I can hardly understand everything. I saw the photos of the links in the previous place but I did not understand if I have to take an external power if I wanted to put a stricia of 3 meters. In other words, how do I need to connect the cables if I buy an inexpensive addressable strip on Amazon? Link to comment Share on other sites More sharing options...
DevBiker Posted November 2, 2018 Share Posted November 2, 2018 There are two ways to connect: 1) Get a Lighting Node Pro (which comes with strips) and a PSU that is separate from your PC's PSU (and is outside the case). Put a switch on the PSU, power the LNP from that PSU, and use a standard miniUSB cable to connect the LNP to an external USB-A port. As an alternate to the PSU, if you can get/build a 5V power source with a SATA connection, that would work too. 2) Run cables from your PC to the outside. Depending on your case, this may require a bit of modification. However, USB header brackets, with the USB ports removed, actually work pretty well for this.

CrazyAngel1990 Posted November 2, 2018 Share Posted November 2, 2018 I like the external LND very much. So after I have to feed the strip with a 5V power supply and the LND takes power from the usb if I understand correctly. Is there a picture or a diagram where I can understand how to colleagle everything? So can I take any strisia addressable? Thank you very much for your help Link to comment Share on other sites More sharing options...
DevBiker Posted November 2, 2018 Share Posted November 2, 2018 You need a SATA power connection; the LNP takes very little power over USB (< 100mA). USB doesn't provide anywhere near enough amperage to run the lights. And Zotty's diagrams on the RGB FAQ would be the best source - he's got several of his running "outside the box".

Found, I looked a bit the various explanations but does not speak to connect the normal led strips. Reading the previous posts I realized that there is a limit of LEDs due to the Amps and the maximum number of LEDs controllable, what are the exact limits of both? Then just connect the two wires as in the picture to make the LEDs go? Link to comment Share on other sites More sharing options...
DevBiker Posted November 3, 2018 Share Posted November 3, 2018 The entire LNP or CP is limited to 4.5A at 5V. You want to keep it at about 2.0-2.2A per header. That's a limitation of the SATA power connector. And it looks like you have it working! Nice!! Link to comment Share on other sites More sharing options...
CrazyAngel1990 Posted November 3, 2018 Share Posted November 3, 2018 Maybe I did not specify that the picture I took from previous posts. I wanted to connect a strip of 3M for a total of 90led 5050, with a connection as in the picture I can or burn everything for too many A? Link to comment Share on other sites More sharing options...
DevBiker Posted November 3, 2018 Share Posted November 3, 2018 90 LEDs is likely a touch more than you have to work with. You would have to check with the maker of the LEDs for their amperage rating, though. Link to comment Share on other sites More sharing options...
CrazyAngel1990 Posted November 4, 2018 Share Posted November 4, 2018 (edited) Specify these values: 9.0 W / m 0.3 W / LED Are they ok even if GRB instead of RGB? these would be: http://www.btf-lighting.com/productshow.asp?ArticleID=0&id=155&cid=001 Thank you so much for the immense help you are giving me Edited November 4, 2018 by CrazyAngel1990 Link to comment Share on other sites More sharing options...
DevBiker Posted November 4, 2018 Share Posted November 4, 2018 You want to keep each channel to about 2A max. That'll be 10W. So you can do a bit over 1m per channel. From there, you'll need to configure the channel based on the number of LEDs. So you might have to actually configure it as a fan rather than a strip. 1 LED Strip = 10 LEDs; up to 6 per channel (60 LEDs) 1 HD Fan = 12 LEDs; up to 6 per channel (72 LEDs) 1 LL Fan = 16 LEDs; up to 6 per channel (96 LEDs) There's the math. Now ... in all seriousness ... you do realize that you are entering into "unsupported" territory. If you need this level of assistance ... where, given the specifications, you can't determine your max load ... you may want to seriously rethink if that's a good idea. Not trying to be harsh, dude - just suggesting. Because you're also gonna need to do completely custom wiring to get it to work. Given the pinouts, will you be able to do that?

CrazyAngel1990 Posted November 5, 2018 Share Posted November 5, 2018 For this I ask you, to be helped because they are able to make the welds connections but here I did not understand how to connect everything. So I understand now how the thing of the maximum controllable LED works. Ok so ineria configuring as LL fans I can do it. Now I have a commander pro, with a connected 3x ML120 PRO and 4 corsair strips, so if I connect an additional LNP, can I control 90LED if I set up as LL fans?

However, you may overload the single port on the LNP. Keep it under about 2A ... you can maybe go to 2.1A (I'd have to check the fuse) ... per port on the LNP. In most cases, 90 LEDs will be more than that. Link to comment Share on other sites More sharing options...
CrazyAngel1990 Posted November 5, 2018 Share Posted November 5, 2018 What a mess, corsair had fun doing a closed system :-( If it became too impossible I took two kits of strips only then I can use only 6 so even there it is not convenient. Given the unified system and the software done so well it is really a pity that you can not easily connect non-proprietary strips. Can I feed them externally and use only the LNP to control the colors? The limit of 2.1A is for sinoglo connector sin or in total of the two?
