as you know if you one an antminer S5 there are 2 open data cable ports on the controller board. I'm looking for these data cables that connect the hash boards to the controller board. Why you ask? because i want to connect the 2 hash board from my second antminer S5 with my 1st antminer S5. I want to do this for these reasons:

1. I want to connect all of the hash boards to one controller. I dont want to have to buy a switch
2. Its easier to manage one controller than 2.
3. its easier to port forward to one controller. i dont want to do anything to the firmware to switch ports. this would make that possible with little work. i also would have to leave my computer on all day so i could remote into it.
4. because its possible and i want to do it. I emailed bitmain asking if its possible to connect 2 more hash boards. they said its possible.


Anyone want to help me with locating these? i need longer ones basically. did bitmain get these cables/connectors custom made?

I tried googling for a while. no luck.

They are custom made cables,  you can easily get the parts and tools to make them though.

Port forwarding to multiple machines is almost trivial even without access to the miner itself (and zero firmware changes), if your router has even basic config ability. Set one incoming port to one miner's port 80, and another incoming port to the other miner's port 80. In a browser navigate to your IP and the first port, you have the first miner. Your IP and second port, you get the second miner. No firmware changes, no local remote access server required.

Not saying that's a great idea, and you'll definitely want to change the webconfig passwords since it's open to the internet.

Also I know that doesn't help you find the cables you want, but it does negate some of the reasons. Also I have some of those cables that I might not need, thanks to an acquisition of some dead S5s a while back.

One other item to consider in making a "4-blade S5 Extreme" miner. The most recent firmware that Bitmain has released will NOT support four blades on a single controller. If that doesn't bother you then feel free to proceed. I personally would keep it as two separate miners. I think Ethernet switches are pretty cheap. A used one couldn't even cost $10, could it?

I would suggest talking to Bitmain support.  I imagine if you want to buy them they will sell the cables.

For other miners they sell parts or have parts for warranty.  So I doubt they would turn you down if you contact them wanting to buy these custom cords.

i have tried contacting bitmain about this before. they were not willing to let me purchase it separately. so i've made my own cable. has been working fine for the past month

they quoted me the price and did not get back after selecting the shipping option.

I'm surprised they are normally very good. Was it the US or China team?

I still suggest OP try to contact them.  I think there is a decent chance of sale.  If in US or China you can easily call them aswell.

I'm not sure what happened on your's stinks it dind't work out.   But normally after talking to them and pick shipping they will send a BTC address to send to and after they send parts.

Anyone knows the name of the connector?

In the help material - https://bitmain.zendesk.com/hc/en-us/articles/204875015-How-to-diagnose-S5-hashing-PCB

They describe it as: Data Cable to Hashing PCB.    Which is a good description.

I believe it's a custom cable(I could be wrong on this).  Not sure on endings what I should consider them.

If you want to use a single controller by more than 3 blades,  you also need software

Software you get here www.perearstike.ee/S5/softold/SD-S5-20150107.tar.gz

It works 100% with 3 or 4 blade.

I can't tell you the exact model, because there are literally a ton, but I can tell you who is probably the manufacturer, and that is JST - here's some of the family of products that I thought looked like close matches:

If you try contacting them and sending pictures, they might be able to tell you for sure...

nice! i dont know if it matter now. i somehow was able to connect all of them to one controller and it only shows hashrate for 2 hash boards. they are all connected though. ill see what my poolside hashrate is....

back to normal. just wasted 3 hours of my life doing this. hope this helps someone if they are thinking what i was thinking.

As someone mentioned earlier, the latest firmware doesn't work with 4 boards - but if you run the older one, I believe it works fine.  There's also the nicehash custom firmware, and I thought I read somewhere that it supports 4 boards also, but don't have any firsthand experience.

I was running the nicehash firmware.

Nicehash/Smith firmware does not work with 4 blade.

There is only one functioning software for 3 or 4 blade.

This is a pure Bitmaintech   software . (There is no longer on their  website for download)  See my earlier post in this thread, and from there you can get the link to download.

Bitmain will not sell the cables to u. I asked a long time ago and they replied about them being custom cabled so im guessing that means basically they are all premade and they ordered the entire batch of cables for every s5 that could ever be made and some so they cant start new orders for only a handful of cables which i personally agree with 100% because they buy in bulk to get the huge discounts on either premade cables or the parts to make the cables themselves but i highly doubt they made them in their factory and its likely they outsourced it to another factory near by. But i can splice all the cables with some digikey ribon cables i have to extend them but thats annoying for sure. I need them for the water cooling kits for s5's.

On another note....i also want the firmware modded to stop the waste bitmain said they will fix but its been weeks since they emailed me that reply so i might need to shoot them another email and ask about the status. Basically the miner will run full tilt with or without connection to the internet. That is wasteful especially if your network goes down randomly without warning for a period of time but also since it runs full tilt 24/7 no matter what i noticed the 80 degrees cuttoff doesnt work. I left the fan slightly unhooked by mistake when i reassembled it and plugged the miner up to my laptop not to the network and when to config it and add a second pool to the miner and i noticed i could feel radiating heat and when i looked at the status page the fan was at zero rpm (my fault completely) but the temps were at 94 degrees c. Thats 14 degrees past the auto cutoff for mining so it should have stopped then waited for it to cool off then start again over and over but since it runs full tilt 24/7 it makes the auto shut off stop working and keeps it running. Now this was only after about a minute of it being booted up so i got extremely lucky but im hesitant to move the miner to another location after finding this out because what if a pump dies or if a fan dies?? It will end up like asicminer prismas all over again. Bitmain said this was going to be fixed for sure but its a hugeeee risk and im not sure others know about this yet because whos stupid enough to accidentally test the auto protection thing for overheatting?? Well damnit!!! This guy is! Ur welcome! Lol jk but ya bitmain said its a built in feature to test the boards out for when network is reattached however long down the road but thats a stupid feature in my opinion. It only wastes the electricity the miners saved and people with comcast know that comcast cuts network connections in md at least without warning sometimes or they reboot stuff that takes 15-20 mins to come back up and authenticate with the main comcast servers so this wastes alot of power especially during a rain storm or just a standard internet outage. Ne one else notice this?? I havent seen other posts about it.

Works for me. 

But  I have almost  lost  water-cooled S5 with this Nicehash soft.

1. With Four blade, he can not turn itself off at 80 degrees.

2. This soft is not been able to work  with  three-or four-blade .

Luckily my 4 blades  all  working , but I got more, as 120 degrees Celsius , after syscooling pump failure.
This is the first time that I had to  replace the hoses after miner overheating.
I'm even pleasantly surprised, that all 4 blades  survived.  After remove the hoses,  came out only  hot steam and boiling water  ;D

https://bitcointalk.org/index.php?topic=902305.msg11147009#msg11147009



But now I have  one bad termosensor, and I have a couple of times a day to make a restart . So I know that the 80 degrees cuttoff works  for me.

Not to sound rude but im confused by ur reply and its probably on my end...u say the cutoff works and it stops sucking up full power when it hits 80 degrees c or higher right?? But u say urs reached 120c+ which is 40 degrees higher then the cutoff. If your refering to cg miner stops hashing then ur right and wrong because yes it drops to 0gh/s BUT the miner is still using 600w at normal 12v power so the issue isnt that it doesnt go to 0 its that its still running in the backround which negates the shut off function that is in place. If they use 600w while hashing and while not hashing something is hashing that isnt visible. Bitmain replied to my email saying im right and that this issue was being worked on by their "engineers" and that they will provide info shortly and thats the last i heard from them. They said it has been programed to run hashes all the time even with no network conectivity it just discards the packets over and over which is y it uses 600w all the time. As a comparison if u look at the sp20's when there is no network connection it stops hashing period. The power drops to less then 50w but bitmain doesnt. So if it hits 80 degrees it should stop all activity with the exception of the controller until a set period of time has passed then it checks again and if the issue is resolved it fires back up but if not it stays shut off until the next check and so on but it doesnt. If one feature is broken the other will not work either so since this whole no network shut off doesnt work it makes the overheating temp shut off not work and just keeps pushing 600w through it until the board fries or catches fire. My damn heat sinks after less then 1 minute were ticking like a warmed up car does when you get out. It shouldnt have hit anything higher then 80degrees not 81 or 82 or anything else.

Make sense??


I should prob add the following:

1. Running stock s5 image not this nicehash image or whatever ur refering to.
2. Not running the latest firmware update from april....i updated when i got the miners and that was to the one with the date of the 7th.
3. Running 2 blades at the time of this issue. I have tried with 4 blades without issues but this actually happened when i separated the 2 miners and went to configure it after placing the controller back on the one that had it removed. It was by chance this happened because again i didnt fully seat the fan cable by mistake which i know was silly to do and im at fault there but that doesnt change ne thing else im saying.

No. Miner only stop hashing, however, miner will not continue give out warm.  But now I have a bigger and better pump.
SC-750WATER PUMP  http://shop.syscooling.com/goods.php?id=26

However, too small radiators for 2 x S5 . I  use a total of three sets of Antminer C1 radiator  connected together.

All my C1 have been rebuilt for S5 style air cooling.


https://bitcointalk.org/index.php?topic=914354.40

anyone know where i could find 2.0mm jumper wires? cent seems to find them

1- The name of this part is called an "ECB SPI Cable"
2- Bitmain will not likely ship it no matter how much you ask; you'll only get run around... I fought for weeks and got nowhere.
     2b- Reason being, they don't have a department for parts only.
3- They're a manufacturer, parts should be the job of retailers... but if you buy from the builder, you're SOL; no retailer sells parts.
4- I guess you could make them, those things tend to go because of a bad connection or grounding itself at the wrong place.

If it is still under warranty, I would get an RMA in motion.
If not, run the miner as it is, keep your eyes opened for something that could work.
As others mentioned, you can make your own wire.
But if you're like me and time is limited, you're better off to mark it as "sick" and keep it for parts.
It's funny the shit you scavenge in mining... both on and offline.

If it's just one miner out of many, just replace buy a new miner and/or sell for parts.

You can take the cables from a s3 and modify them to work. Thats what i do.

exactly!! this has been confirmed by support that its caused because bitmain set the miner to run test hashes for whatever reason. this causes the miner to mine locally and constantly discard the hashes because they cant be submitted anywhere. bitmain said it will be changed but i still havent seen said change made yet and judging by their updates i might not want to upgrade to this change anyway because it breaks support for 4 boards. but really this feature is wasteful and not needed at all! it defeats the purpose of having the miner stop hashing when it hits 80 degrees because in the backround the miner will just continue to hash away. sure it isnt submitting the hashes to a pool but it is still sumitting hashes....just into the trash pile locally so again it doesnt actually stop hashing.





now on a side note who wants cables?? i can make them for people....noy spliced together cables either but 1 solid cable allowing folks to connect 4 boards to each controller....the only thing is you will need to reuse the plug from your current cable. so you will have to pop the old connectors out of the plug which takes all of a few seconds and then you slide the new custom length cable in there. i will start a thread in the for sale section when everything arrives but until then shoot me a pm if you want cables made. i can take pp and btc as payment and inside the us it wont cost more then 2 bucks per shipment since i can pop them into bubble mailers i use to ship stuff on ebay so ya. outside the us will cost whatever that costs. i made my own cables by splicing them before finding the stuff to make them myself and let me tell u splicing them is a huge pain in the ass even with the use of the "helping hands" tool.

but ne way lmk if interested via a pm so i can guage the interest in this and see if its worth offering the service to folks.

2.0 mm refers to the 'pitch' or the distance between terminals if I understand correctly.

Are you looking for just wire, like to splice your existing? I did that with 22 guage 'hookup wire' from Radio Shack.

I thought, based on your screenshot, that you already had found longer wires or spliced them or something, and that you were using some nicehash firmware. NOTE: I just spliced my connectors and, at first I had the same problem as you, no, or very few extra hashes (mine actually went up to like 1300, oddly), even though the hash boards show up as all o's. Others have said the latest firmware doesn't work. So I flashed the Jan 7 firmware that I happened to have saved off, and it WORKS! Getting 2300 gh now. I tried to post a pic but I'm getting 'invalid image' so I'm not messing with it. But, it works!

So don't give up on it. If you want the Jan 7 firmware I can get it to you. It's still the .tar.gz file that bitmain provided.

Should it not be fairly simple to write a script which will stop cgminer if loss of connection to the internet is encountered?

(I don't know why I'm posting that as a question. It is)

That cgminer stops actually is the problem. It can happen that the chips continue to do work even if cgminer stops, which since I saw it happen once on a Compac I think it's more a chip thing than cgminer. But cgminer I believe controls the fan speed, so when cgminer drops out so does the fan. What you need is something independent of cgminer to wrangle the fan based on device temperature.

Also I'm not sure how many people are still worried about it four months after the last post in this thread.

Hmm. Interesting. I wonder if there is a way to make the chips stop working. I'll have to try some measurements.

And I've resurrected zombie threads a lot older :)

Or do what many of us did.
Cut the blue wire and fuggedaboutit.

I do think it is a cool project to run several hash boards from one control board, but I still put second fans on my S5s and clip the wire.

I have one S5 with a flaky hashboard. I never know what I am going to get when I cold boot, and then software boot. Usually two xx.
Input power is great.
Methinks temps are good.
I need to get off my arse and swap the boards and then check cables if needed. But she is running today. I have a feeling she will not do that for too much longer though. I thought I'd have a reason to go move things around and pull her by now. Maybe next week.  :(

Mildly curious (only mildly) about how the blades are controlled and whether it would be possible to replace the controller board with a Pi (for example). More effort than it would be worth for me though.

(Sorry, definitely getting off-topic there)

I've got a two-chip test board that I can wire up to either an S5 controller or to a USB adapter. Since we don't have multi-chip code yet (soon though) it was fairly irrelevant to run it off the USB adapter but irrelevant is not impossible. Shouldn't actually be that difficult to run an S5 board then, I think, provided you had a working cgminer driver.

There are a few ways one is use this http://www.ebay.com/itm/181694032917?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT I have one or two i need to test out if they work they may save a few S5 but not stop it  .

but they keep selling on ebay it seems so they may work, i haven't got around to testing the ones i have but plan to soon.

as for S5 cables 16 pin or 18 pin  


J4bberwock ,  said he will have a lot in stock at the end of the week . better then the ones on the S5's now, I believe it, by some stuff i  have bought form him, it's better then bitmains stuff as a replacement.

Since this thread is already here, I might as well use it. Today I resurrected a dead S5 board but it's the early version with 16-pin cable so I had to borrow a controller to test it. All the controllers I have running around use the 18-pin. I have the 18-pin signal pinout already figured out but I haven't done anything with a 16-pin before today. Anyone know offhand what difference there is between the two?

I am not certain, but the top diode in the level shifters and an additional buffer chip (U3 on the bottom Stage) were fitted when they went to 18 Pin and I think it's something to do with Test Mode for the chips?

Rich

I repeat my earlier post. Maybe this will help.

I share  again one finding .

You can use new S5 Hash PCB  ( 18 pin connector)   with S5 Control PCB  (16 pin connectors) Need only a 16 pin cable.
Picture of my water cooling S5 project    3 x old blade + 1x new 18 pin blade.

That's great, but it's the opposite of what I need. I have 18-pin controllers and a 16-pin board. If I have time today I'll just do the probing and figure it out.

How do you create the image? I took the files that you posted before but doesn't work for me. I need to connect 4 blades with one control board

This  works for me with 3 and 4 blade
SD-S5-20150715-fan_ctrl.tar.gz

www.perearstike.ee/S5/fan.cntr/SD-S5-20150715-fan_ctrl.tar.gz

Thanks for the link. I'm about to have to run a few S5s with 4 boards and I was worried that I might run into problems with the software because of a few things I've read. I'll try reflashing with this software if the stock one gives me any grief.

Thanks for the link, but I meant to the .imgc file yoy have it? Or can I just copy the 4 files over any SD to put it on the control board? I'm asking because I've read from Bitmain that I meed a soft (like HD Raw Copy) to create the image

All right i never done this before, so I've to select "Upgrade" on the miner's menu and choose which one? I mean to the files, in my menu appears: Backup/Restore ; Flash New Firmware Image (and you already said that's not image file)

select "Upgrade" on the miner's menu, then Flash New Firmware Image  and use this file SD-S5-20150715-fan_ctrl.tar.gz

Hi again

I tried this morning the upgrade and i got this: "tar:invalide magic tar: short read"

That error message were shown immediately and said "Upgrade Failed"

Please help

I downloaded and tried to upgade  now,  all works.
You can not unpack the file, before upgrade.

Can you send me the file again? maybe the old link it's broken. I tried to make the upgrade without the others blade (3 y 4), can be this the problem?

Link is not broken. I used downloaded file.

Im about to add a third hash board too I'd expect the file is still good to use? thanks btw Tupsu! :)

also on the topic about data cables if anyones still looking

or buy from me S5+ single cube and (re)use your S5 controller.
https://bitcointalk.org/index.php?topic=858962.0  ☆ Offer your price ☆

Latest bitmain S5 software still works with 4 blade, i use it with S5+   3 blades at freq 325  and with S7 controller

My S7 does this.......  running full-tilt when connection is lost.

I sent you a PM

& Thanks for the clarification on the FW, it saves me flashing it :)

whats the speed on an S5+ blade?
will it work on the S5 controller or do you need the S5+ or S7 controller for it?

I actually have a question about the S7 controller, some come with 3 connectors and I have seen some full of them,
can you just populate the connector sockets (if you know what part it is)to add more or are there smd parts needed too?

S5+ single cube is 2500 GHs  (one blade about 850 Ghs)

It works with S5 controller and with S7 controller with 9 sockets.
Works with S5 software and with S5+ software

With S5+ software and S7 controller you can put together  3x S5+ cubes in one single unit. 7500Ghs

ohh thats awesome thanks

i made a diy mount for my one blade and extended the data cable, wish they had sold longer ones,
however cooling is not enough, also had to use a second supply as my 1440w only puts out that on 220vac
shuts down when it goes into hashing routine
so now Im looking for `some used end plates so i can use a spare 120mm fan I have to cool the blade
I`m going to buy another cube sometime soon but trying to work with what I have for now

nothing fancy for a diy

Ok just an update

the 3rd blade works great, clocked at 450 i get temp of 62 and 1,838.90gh/s the other blades run at 52,55 but have a stock fan in the cube
so im looking for a stock fan and awaiting cube end plates to mount it in I expect that will help temps lots, have to make a spacer as the second sink to hold the cube square i expect, & plan on attaching it directly to the first cube and using that plastic side as the new Siamese twin cubes side thats exposed

I didnt run it longer than a few minutes to try the hash speed after boot

what are the max safe operating temps? I always try keep it under 60 if possible

If anyone needs extra long data cables (~12"), I have a couple hundred of them.

awesome sent you a PM :-)
dont really want to go through soldering again

I am really glad I ran across this post.  I have 2 s5s.  the controller board went bad on one.  I simply turned them both on their side toward each other, then connected the data cables and the fan on the bad s5 to the controller board of the good controller board and walla!!!!  4 boards running at 59C and clocked at 400mhz.  Thanks a great deal guys.  Probably never would have tried that without seeing this post.
