The home page shows the basic information of the mining machine:

  1. The current time, time zone, hostname, IP address, MAC address.

     

  2. Mining machine chip count, blade count, temperature, average nonce count per minute, 5S and average hash rate statistics, returned nonce count from chip, accept/reject/error nonce count and rate from the starting up time.

     

  3. The running time of the machine, PLL and serial baud rate parameter.

     

  4. The chips count, the test result bitmap, returned nonce count from chip and bitmap during last 30 minutes, accept/reject/error nonce count and rate, the current task difficulty, average nonce

Mining configuration

  1. Modify Host Name: As shown in Figure 6. First click the [change] butto and enter in new host name then click [restart] to activate it.
  2. Click [reboot] to restart the system
  3. Click [restart] to restart the mining software
  4. Configuration
  • Click the [Config] button on the left side of Figure 6 enter in the configuration interface which is mainly divided into 3 parts, as shown in Figure 7.

Part One:

  • Click the [✓] button to display the details of the selected mining pool.
  • Click the [Top] button to set this mining pool to the highest priority.
  • Click the [Stop] button to cut off the connection with this mining pool.
  • Click the [Delete] button to delete this mining pool.

Part Two:

  • Type in the mining pool address in Pool URL, name of the miner in Pool User, and the password in Pool Password, and then click the [Add pool] button t add the new mining pool to the mining software.

     5. Set Temperature Reminder

Fill out your mail address, alarm temperature interval and temperature limit, and click the [Set Warning Param] button to complete the mail reminder setting, The alarm temperature is used for automatic frequency adjustment. The mining frequency will be reduced automatically to protect the chips when the current blade temperature is over the warning temperature. The maximum alarm temperature can not be over 70°C.

     6. Set Fixed IP

The miner is preset to use DHCP, If you want to use a fixed IP, you need to manage the settings as follows:

Fill out the fixed IP, subnet mask, network entry, enable IP Enable, and then click the [Set IP Config] button. If you want to return to DHCP mode in the future, you only need to remove IP Enable and click the [Set IP Config] button. note that some routers require corresponding settings to use fixed IP addresses for mining, In that case you need to have a full understanding of the router you are using to correctly use the fixed IP address for mining. the IP mode settings need to restart the machine to take effect.

     7. Save Configuration

After setting all the parameters, click [SaveConfiguration] to save all the parameters, If not saved, these parameters will become invalid after restarting the miner.

     8. ASIC Chip Parameter Settings

The maximum working frequency PLL preset by the miner is 680 Mhz. You can modify the upper limit of the frequency by entering a valid PLL value, and then click the [Set PLL] button to complete the setting. Unless there with professional advice, we do not recommend you to change the preset PLL frequency. The new highest PLL frequency will take effect after restarting the system.

Part Three:


     9. The updateMiner/rollbackMiner/restoreMiner function is used to upgrade               and restore the version of the Miner program.

The current mining software version is shown in the third part of Figure 7, similar to cgminer 5.3.6.

Update

Since there may be bugs in the version of the production test or the firmware has been optimized in the future, it is suggested that the user should check whether the firmware version of the machine is consistent with the latest version on the official website as soon as it is received first time. If not, the latest version should be downloaded and upgraded.

Update your machines by DevManager.

Download the update package from our website www.ibelink.io, As Figure 8. Select the device that you want to update as figure 9, And then Click the button [Select Update Pack] to choose the update package which you can. The tool DevManager can also be downloaded in the item "Others" of the same page. Then click [Update Selected Dev] to update the device you selected. Or, you can click [Update All Devs] to update all the device by your searching. More details you can see in Figure 8-10.

FAQ

Can iBeLink N1 mining machine be over clocked?

No, do not do this. Overclock has a high possibility of causing permanent damage to the ASIC chip.

How to maintain the efficient operation of iBeLink N1 mining machine?
Keep this miner running at cool ambient temperature as much as possible. Maintaining the ambient temperature below 35°C can achieve good efficiency.
What Does DIY problem diagnosis and repair meain?
The design idea of iBeLink N1 mining machine is modular design. The original intention of this design is to make it easier for miners to diagnose and repair by themselves when they encounter problems with the mining machine without having to send the entire mining machine back to the manufacturer for repair. Most of the problematic miners should be able to resolve or reduce the loss of computing power through diagnosis and repair. We will publish a series of "how to" videos to help miners achieve DIY. We believe iBeLink N1 will provide the best product life cycle holding cost.
Why can't my browser configure the mining machine parameters?
It is recommended to use Google's Chrome browser to save the miner configuration.
What does the bitmap of the chip on the homepage mean?
When the mining software starts, it will detect all ASIC chips on each blade. If the chip at the corresponding position is normal, then its bitmap value is 1, otherwise it is 0. If the 60 chips of each blade are normal, the value of the bitmap will be 0xfffffffffffffff, and the corresponding binary value is 60 ones. If the first chip is abnormal, the value of the bitmap will be 0xffffffffffffffe, that of the parameter Chips map. When the chip calculates the correct result, the value of the corresponding position is 1, otherwise it is 0. the value will be updated to 0 every 10 minutes.
Why sometimes the number of ASIC chips on my homepage is less than 0xfffffffffffffff?
Due to electrical instability and possible bugs in the software driver, the checking process of mining software may miss out 1 or 2 chips occasionally.
Why does the mining software restart automatically?
The mining software supports automatic recovery from network or driver errors and has a hardware watchdog to monitor the entire system. When an abnormality is detected, the mining software automatically restarts to try to recover itself, so it's normal that the mining software occasionally restarts automatically.
How to recover mining software from a crash?
Update the devices as 2.4.
Why the hash rate statistics results are different in different mining pools?
The mining software performs hash rate statistics based on the returned nonce. The difference in the difficulty of the mining pool will result in a different number of nonce, which will affect the hash rate statistics and lead to different results.
Why my worker is not in the main mining pool but in other mining pools sometimes?
When multiple mining pools are configured, the mining software will mine in the most important mining pool (main mining pool), but if the main mining pool loses connection due to the network and other reasons, the mining software will automatically switch to standby pool to continue mining.
