Topic: S7 controller has nine 18- pin jacks So what can we do with it? (Read 10954 times)
So... Will Batch 6 S7 IO board handle 6 S7 blades?

Unless the IO board has a nice high-current 3.3V buck regulator on it, and the FPGA on there functions as an IO expander.

Are people still doing this one controller and 6 blade or 9 blade hack? I'm confused as some of the above comments make me think its not a good idea. I have a batch 7 that has 9 18 pin slots but came with the 162 chip board. Can I take the 162 chip boards out and put in 6 135 chip boards as long as I have enough PSU?
My 1st guess is that the BB's GPIO circuits can't handle the load of that many hash boards tied to it. Betcha Bitmain is using unbuffered BB' signals and that when overloaded it takes out part of the BB....Since small computers like RasPi, BB, Audrino, et al are not known for um, 'robust' power protection, if the feed for the 3.3v used for GPIO is overloaded that could lead to Majik Smoke getting out...

any help to find controllers for sale ? I can't find it :-(

Can you test if it's the IO board or the BeagleBoner itself that is messed up? I believe the 'boner is the same on the S7 as is was for the S5 and S2 (but someone who can say for sure should verify that). If the IO board is okay, I've got a stack of the 'boners laying around.
Well , I think the IO is dead is one controler , and the BB is dead in the other. Because the effect was not exactly the same.
So I trid to melt the part , and now I have a controller fully ok , and a controller fully dead (with BB dead from one S7 and IO Dead from the other).
The good thing is I have one of the two s7 back in game , but the bad news is I have to get a whole controller unit for the second one now.
Any good deal somewhere ?
I wrote too early , my rebuilded controller did not work for long , after one hour it stopped hashing too. I guess today small unexpected power shutdown got it burned too... ultra bad luck.
It is weird because the s7 is making hot air , but the green blinking led (for hashing) doesn't light..
So I think I still need two controllers ... or one able to drive 6 blades.
Thanks guys

You can use B.B.B. from S5 together with S7 controller.
Even S5 whole controller works with S7 software. (look at the picture S7 Batch8 2 blade with S5 controller)
But as it turned out, it shows the wrong temperature. always around 46 C

It seems that when using the S5 Controller with an S7 Blade that after booting it reads and reports a temperature, however no further readings are taken. If you boot from cold you get a low number, but if you then reboot after a few minutes you get a higher number?

Completely off topic, but "deserve" is one of my least favorite words.
Sorry. How about 'earned'?

You want some to play with? I'm already booked solid on stuff I know what it is. And, to be fair, some of them came from your miners anyways. I figured on putting up a sale post sometime to get rid of 'em anyway, I got about a dozen.
Heh heh.. I already have 3 new-in-the-box Pi's from the A1/AMT days that I've yet to do more than open and look at.... Not to mention that I still have 6 more s5's and a couple s3's, s4's and even 2 s2's kickin' around. And the Demon of Time is at work here as well. 
However, the cryptoGlance/Pi seems rather appealing so I WILL try it on at least one of mine. As for the pulls you got - sell'em off. You deserve the money.

Here's an off the wall thought for using PI's and Boners...I'm currently playing with CryptoGlance for monitor software and in a nutshell, it sets up a Command/Control server on whatever PCish thing you have around. It's open source and loves Debian Linux. They have pre-built RasPi images for it. So...
How about cobbling together some some RasPi or BB plug& play cryptoGlance servers with them?

i would love to know what i can do with these pin connectors
sorry for getting this old post up,
but after an thunderstorm , I got 2 controllers out of service on batch 9 S7s..
I don't have old S7 with controllers able to drive 2x3 blades , so I 'll have to buy new 2 new controllers (1 by damaged S7), or maybe 1 old controller able to drive the 2x S7s.
Would you guys advice me ? the best place to get some ? (cheap and fast ?) maybe another idea ? thank you !

I just hooked two units together via the rails and then unmounted both control boards and place a single bb board and data port board in between the two miners held in place with a little velcro. The original cables the S7 ships with are plenty long enough when set up this way...

point them upwards top to top that allows for vertical and hot air raises.
stack them on a box fan which allows for more air to help fans. also if fans fail the box fan may save the day.

It would seem to me you could lash together two S7's with a single controller if you were to lay the miners on their sides, so that the "Top Side" were facing each other. Kind of awkward to wire up, but it shouldn't take any "long cables" to accomplish.
It would be interesting to know if the S7 cooling actually requires that the blades be vertical to work OK. While it's obvious what the "expected" orientation is, does it still behave well if it's laid on it's side?

thats what i did, works great.
thx for sharing the info guys but i noticed they do run slower than individual controller
how much slower? 4800 + 4800 = 9600
are you dropping to 9500 or 9400 or worse?
I theorize the controller is running 4 fans vs 2 so that the pcie runs volts say 12.0 vs 12.1 and thus lower speeds.
I also think 2 s-7s on two controllers give two sets of psu readings so if one psu is 12.1 and the other is 12.0 one s-7 will run better.
but 1 controller uses the lower reading so it reads the 12 and both s-7s run lower.
voltage is minimum of 12.2V & i might up it soon (12.5V) after modding psu's.
i can run 3 s7's with 2 x 2000bb psu but i'm running 1 x 2000cc per s7 so power is not the issue.
i think finsky might be right about connection between chips & controller ?
after i've modded psu voltage to 12.5V or more i will try again & see how it goes.
tests will be at stock speeds. 12.5V & 12.8V will be tested & see if there's any difference.
lucky for us, no need the long cables like the s5's to merge 2 in 1.
more ideas & suggestions, results are welcomed.

Phillip, wouldn't you think that the voltage at the chips (powered separately than the connector powering the controller) would have more of an impact on performance? Maybe it has more to do with the amount of connections between all the chips and controller or something? I thought I remembered sidehack touching on the idea of communications between chips and controller and some limitations.
