MINING GUIDE

  • Please download the driver: http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
  • Set up the driver “CP210x_VCP_Windows”(For 32bit OS, please install “CP210xVCPInstaller_x86.exe”; for 64bit OS, please install “CP210xVCPInstaller_x64.exe”).
  • Download the software package needed (It’s a .zip file, please click “file → download” to download it): https://drive.google.com/file/d/0B-_jcpU1s5dgNEZlTjdQRi1OOTA/view?usp=sharing
  • Connect all the cables needed. After you connected the PSU, the fan of the miner should be working.
  • Connect the miner to the USB port of your PC.
  • If your PC shows up “setting up the driver”, please wait it to finish.
  • Run the zadig_v2.0.1.exe in the software package you download.
  • Choose “Options—>List all drivers”, and then in the pull-down list (as shown in Picture 1(see below)), there are one “CP2102 USB to UART Bridge Controller”, choose it and click “Replace Driver”.

  • After the replace work done, please close zadig.
  • Pull out the USB cord of the miner and please power off the miner.
  • Then Power on the miner again.
  • Connect the miner to the USB port of your PC via data cord again, and please note: insert in the same USB port as before.
  • Change the “autorun.bat“. Use the notepad to open it and modify it. The mining command in the .bat file is as the following, please change the “pool_address_1, pool_address_2, miner_account_1, miner_account_2” to yours.
cgminer.exe --bmsc-options 115200:0.57 -o pool_address_1 -u miner_account_1 -o pool_address_2 -u miner_account_2 --bmsc-voltage 0800 --bmsc-freq 1286
  • Run the “autorun.bat”.
  • Then it should be working, like the picture showing:


 

Run more than one miners

There are two ways to run more than one miners together:

  • METHOD 1:  Connect all the miners to the USB port of your computer, and run them together.
  • METHOD 2:  Use a USB-hub (Which is connected to your PC) to connect all the miners and run the miners.

Here is the guide about how to mining with 2 miners with a USB-hub. Whatever ways you run the miners, you can have a look at this guide as a reference.

  • First, refer to the {mining guide} above, run each miner individually to confirm the miner is work well.
  • Connect all the miners to the USB-hub, then connect the USB-hub to the USB-port of your computer. (Some USB-hub comes with a individual PSU, in that case, you should power on the PSU first.)

  • If your PC shows up “setting up the driver”, please wait it to finish.
  • Run the “zadig_v2.0.1.exe” in the software package you download.
  • Choose “Options—>List all drivers”, and then in the pull-down list. There will be several “CP2102 USB to UART Bridge Controller” in the list, choose each one and click “Replace Driver” (Or “Reinstall Driver”). For example, if you connect 2 miners to a USB-HUB, then there will be two “CP2102 USB to UART Bridge Controller” in the list, you should choose each one and click “Replace Driver”.
  • Please remeber which USB-port on the USB-hub the miners connected to.
  • Disconnect all the miners from the USB-HUB. (But please keep the USB-HUB connected to your computer.)
  • Power on one miner, then connect the miner to the same USB-port the miner connected before on the USB-HUB.

  • Run “autorun.bat”. This one will work.

run1

  • Then power on another miner, and connect it to the same USB-port the miner connected before on the USB-HUB too.
  • Then the black console will show some infomation about that another antminer U3 is detected. And the console will run all the two miners together.

detected run2

  • Important: you should connect the miners one by one to the USB-HUB. DON’T connect all the miners at one time. (Or the autorun.bat may get crashed.)

 

Trouble Shooting

  • Q: I got many HW error when mining, why? And what can I do?
  • A: If you got some errors when mining, that’s normal. But, If you got many errors, please try to:
    • Stop mining, power off the miner, and wait for some seconds, start again.
    • Try to run the miner one by one, if it is running ok then the miner is ok. It is recommended to connect 2 units at most to one computer. (When tested, HW error may occur if connecting more than 2 units to one PC)
    • Try to change to another mining pool.
    • Is your network works well? Can your computer connect to the pool? Please try to change to another mining pool.
    • Change to another USB port. Change the USB port which you connected your miner to.
    • Change a PSU. If you use your ATX PSU for the miner, please change a more powerful PSU for the miner.
