At the top of the logo, there is four signal LED for showing the status of the mining board respectively.

II. Installation

DM11G miner is consisted of a power supply, but need an extra power cord and LAN cable.

The installation of the miner is very simple, plug in the power cord and LAN cable. Then turn on the main switch to start the mining.

III. Software Configure

Before running the miner, two things needed to be prepared:
1. Get the receiving address of your DASH wallet.
2. Register a mining pool, recommended using Cybtc Mining Pool, dash.cybtc.com (founded in January 2017, providing an efficient and stable mining experience, is currently the world's largest DASH mining mine pool.)

First register.

Then activate the account.

Log in and create workers.

125856timxmnpfgp7rimmx.jpg125857spmbqnbbups9q99s.jpg

The miner has DHCP function and can get the IP assigned by the router. Input the IP of the miner in the browser  (PC in the same LAN). You will see the control panel of the miner.

Then click "setting".

125900m39f91bu990s0hvs.jpg

The mine pool currently provides two sets of server address. Input the work names and passwords to two address respectively.

Main mining pool address: stratum+tcp://wk1.cybtc.info:8888
Backup mining pool address: stratum+tcp://wk2.cybtc.info:8888

Then remove the default settings (which is for testing) of the worker.

125903jz47dl9ln5vv5lll.jpg

Keep the two sets of workers setting for your own.

Note: As the control panel page will refresh every 40 seconds, the setting needed to be input before the page is refresh. Please check the input setting is correct. If not, please input once again.

Finally, click "Save Configuration". Then the miner starts using your setting to mine.

After a few seconds, you can see worker status at the mining pool and the hash rate of the worker should increase slowly.

When the miner is in normal operation, the four status LED show blue.

IV. Test

The DM11G miner will automatically adjust the frequency (hash rate) according to the temperature, the maximum operating temperature is 42 degrees, if above 42 degrees, it will decrease the frequency operation, the hash rate will be reduced.

125908tcnbn8ydbyqzdndy.jpg

The test was conducted in a room with a temperature at about 23 degrees, and noise is about 40dBa.

At the default frequency, 600, the hash rate of the miner is varying between 9.8G and 11.8G. The average hash rate is about 10.8G for long time operation. There is no significant fluctuation in the curve of hash rate.

125910v5rr3qm3f2lkf333.jpg
125910drb4j7fckty7jyqy.jpg

In this conditions, the hash rate shown on the mining pool is 10.8G, and the power consumed is about 870W.

For the noise level, 82dBa is measured from  20 cm to the miner.

V. The components of the miner and some concerns:

a. The miner is composed of four pieces of mining board, and which is equipped with power supply (the following shown from official page)

125914vuuihnuzgfznja3u.jpg

b. If the room temperature is above 30 degrees, the temperature of the miner will reach 38 degrees or above.  The frequency will be drop automatically, and the hash rate will be reduced. The simplest solution is to increase the circulation of air, or best deployed in an air-conditioning room.

VI. Summary

1. iBeLink DM11G is a X11 miner with the highest hash rate at present. The power consumed is about 870W. The miner is well made, easy to use, convenient to carry and deploy.

2. The noise of the miner is high and 82dBa is measured from  20 cm to the miner. It is more suitable to deploy in a factory.

3. Consist of controller and power supply make the miner in a compact size. The automatic allocation of IP makes it plug and play.

4. In the operating environment with better temperature control, the operation is stable for a long time, and the curve of hash rate shows no great fluctuation.

5. Shortcomings:
a. The design of the air-duct is too long, which affect the effective cooling. The 5400 rpm cooling fans make the noise higher. The temperature protection of the miner is locked, the maximum operating temperature is only 42 degrees, this temperature in the southern summer is difficult to achieve the ideal operating environment.
b. The instruction of adding workers at control panel is not clear.
