Topic: LightningAsic usb miners based Gridseed GC3355 Tech Support Thread - page 30. (Read 73513 times)

Also, does anyone know if it is possible to run 10 miners in LTC mode off a single power supply?  Or more, say 20 or 40?

I'm thinking of doing something to others in this thread, use a 4U case and remove the fans.  Run 20+ miners, and use some fans at the front/rear of the case.

Can anyone figure out how to get into the controller?  Is it possible to hook up via USB to the computer and access the filesystem somehow?

It can be any pool especially if you are gonna use scypt only mode. (you just need the info in there)

Thanks. I was going to try that next. Now I have to find a BTC pool to join.

Ok, so I've solved this based on what I saw on this post by velvethammer2 (https://bitcointalk.org/index.php?topic=421921.900).

Here's what I did:

1. I added in my LTC pool info (just 1 URL/worker/pwd)
Ex:  stratum+tcp://crypto-coin-pool.com:3333
      myworker.1
      mypwd

2. I added in BTC pool info (same as shown in #1 but for a BTC pool)
NOTE: Do NOT check the box for "enable BTC".  Just add the info in the fields.

3. Click on "Save and Restart".

4. Count to like 5 to ensure the save is done.

5. Turn off (or disconnect) the USB hub from the controller.

6. Pull the power cord out of the TP-Link controller.

7.  Count to 5, then plug in the power cord on the PT-Link

8.  Make sure it starts up fine, the Dashboard shouldn't find any miners attached to it.

9. Plugin the USB hub of miners.

10. That's it...it should work and the error message will no longer show at the top.

I'm able to start mining now! :-)

Looks like we're in the same boat...

I've connected the wires/cables for a single miner to the controller/usb hub.

Now when I go to the GUI interface I keep getting this error message:


Here's what I've tried so far:

1. LTC mining and config only.
2. I've tried rebooting the controler (unplug it, plug it back in).
3. I've tried adding more than 1 miner to the hub.
4. I've tried starting the controller first, letting it settle for 2-3mins, then plugging in the hub and 1 miner.
5. I've tried a couple of different miners (in case the first 2 were bad somehow).
6. I've tried different USB cables to the miners (in case a few were bad).
7. I've tried plugging the single miner into different USB ports on the hub.

In all of the above scenarios, the GUI throws that PHP error at the very top of the screen and the LTC miner always shows "Offline".

I pinged Jack on Skype, and he tried to put me in touch with one of his tech support persons -- but that person is offline -- Tech support person is located in EU so very likely the he's off enjoying his Friday night.

Suggestions?

I attached one miner to see if everything is working. The miner spins up and lights blink. However, I get the error message at the top of the webpage:

"Warning: Invalid argument supplied for foreach() in /www/class/miner.class.php on line 414"

The controller recognizes the miner (Name: LTC Miner 1:8, and changes depending upon which slot I plug it into). The status of the miner is "offline".

Any thoughts on how I can get it to start mining?

For the script pool url, I am using: "stratum+tcp://crypto-coin-pool.com:3333"

Power connection summary:

Note: I received the PSU configured for 220 volts, and a power cord not compatible with my country. Fortunately, I have lots of extra power cables. Standard computer cables work fine.

1) Set the voltage switch on the side of the PSU to 110 or 220, depending upon your country (110 for USA).

There are 9 terminals on the PSU. They are number. From left to right, they are 1 through 9.
Terminals 7, 8, and 9 are Ground, N, and L, respectively


2) Cut the power cord and expose the wires. The wires are colored Green, White, and Black. The the USA, the Green is connected to the center terminal, the white to the wider terminal, and the black to the thinner terminal. Connect the wires to the PSU as follows:

Terminal #, Terminal Name, Wire Color, Purpose
7, Ground, Green, Grounds the outside of the case so your don't shock yourself.
8, N, White, Neutral - This is the return path of the electricity to ground.
9, L, Black, Line Voltage - This is the power from the power company.

The power cable for the miners has red and white wires. Red is connected to the inside of the terminal, and white to the outside. The power to the miners is DC, so direction matters.

Terminals 1, 2, and 3 supply +12 volts. They are all identical. As far as I can tell they are all interconnected, so it doesn't matter which ones you use.
Terminals 4, 5, and 6 are Ground. They are all identical. As far as I can tell they are all interconnected, so it doesn't matter which ones you use.

3) Connect the Red wire to terminal 1, 2, or 3. Connect the White wire to terminal 4, 5, or 6. Repeat for 5.
4) Do all of the above for the 2nd PSU


It matters, but it works either way. With A/C power, the electrons go both ways so either way works. However, N or Neutral, is the return path to ground of the power. In theory, you will not get shocked if you touch that wire.

For safety purposes, devices are wired assuming that a specific wire is Neutral, and the other Line (live). It keeps that wire away from anything that you might come in contact with.

This guy posted a picture with the black/white/green:

I appreciate the clarification!  I've got to run out now for a bit for errands...so I'll get back to this in a few hours.

I mean I have the same cables as you, as in the red/white and the green/white/black.  The white/red cables go according to the Gridseed guide picture and the PSU cables go like this picture:
https://dl.dropboxusercontent.com/u/117000/scryptminer/PSU2.JPG

So if I understand you right, in the US it doesn't matter if I switch black/white wires around for this PSU?


I've already flipped them both to 110 (was the first thing I did)...

To clarify "Mine were the same"...do you mean the power cables for the miners or the power cables for the PSUs?

Mine were the same.  Another helpful hint is to make sure and flip the black switch on the side to 110 from 220 or it won't turn on.

Electrical wiring color codes :

For US and Canada power cord :
Ground => green
Phase / Neutral  => Black & White

Ok, so my PSU wires aren't coloured the same way as shown in the PDF user guide...infact they look like yours, green/white/black.

Here's the wires (http://imgur.com/ALXhBM1)...

From your picture it looks like you've go the wires connected as follows...would you please confirm if I've got this right?

black - the "L" terminal -- 1st from the right side.
white - the "N" terminal -- 2nd from the right side.
green - the "upsidedown tree" terminal -- 3rd from the right side.


Incidentally the power cables for the actual miners are coloured RED and WHITE...so that follows what's shown in the PDF...so I think I should be ok with using them the way it's shown (RED to +V; and WHITE to -V).

FWIW the colors on my power cables didn't match the PDF so if you have a multimeter I would use it to match up the bare wires to the plug.

Ok, I'll try to take some pics of the process in case anyone else has to deal with it.  Anyways, I've gotta run back to the office...sadly this will have to wait till later.

Thanks for the help!

Yep, just use scissors and cutters. Be careful not to expose the wires when you'll remove the black rubber on a few centimeters. Separate the three cables and expose a few mm of wire at the extremities.
Look at pictures from PDF guide for color matching.

Good luck

Hi Guys,

Ok, so my miners just showed up...and I had a few mins on my lunch break to just make sure all the parts I needed were there.

Turns out I was missing a micro-USB cable which connects the power plug to the TP-Link device...luckily I have spare micro-USB cables laying around.

HOWEVER!

It seems that I was perhaps sent the wrong power cables for the 2 PSUs!    Take a look at this picture (http://imgur.com/g58U3Zh) and you'll see that I've got 2 standard power cables for computer PSUs...and not the "open wires" that are needed to connect to the PSUs sent to me.

Any suggestions???  Should I just cut the ends off of these cords??  I'm out of my element when it comes to electricity so I have no clue what to do about this.
