Bitmain’s Test Fixture: Using Conversion Files and Test Files

If you have ever wondered how to use conversion files and test files with Bitmain’s test fixture, then this blog post is for you! We will walk through an example of using both files to ensure that your test results are accurate. By the end of this post, you should have a better understanding of how to use Bitmain’s test fixture to your advantage. Let’s get started!

Overview of the Antminer Chips Fixture

The Antminer chips fixture is used to test and diagnose ASIC miners. It is designed to connect to the miner’s hashboard, voltage regulation cable, and power supply to measure its performance accurately. The test fixture provides detailed data about the miner’s hashrate, temperature, chip numbers, signal transmission detection and more. By using conversion files and test files with Bitmain’s test fixture, miners can quickly identify any potential problems causing an issue with their mining operations. Additionally, it allows users to detect bad chips on the board which may need replacing or repairing for optimal performance levels. With all of this information at hand, users can quickly troubleshoot most issues related to their mining hardware so they can get back up and running as soon as possible!

How to Install Putty and Connect the Antminer Chips Fixture

Installing Putty and connecting the Antminer chips fixture is a relatively simple process. Still, it’s essential to take the time to make sure that everything is set up correctly for the test results to be accurate.

The first step is to install Putty on your computer. This is a networking program that allows you direct access to the command line interface (CLI) of an Antminer. To do this, simply download the software from its official website and follow the installation instructions. Once installed, connect your system to the Antminer chips fixture using a USB cable and open Putty. From here, you can use CLI commands.

You can begin testing by downloading both conversion files and test files specific to your chosen Antminer model. These files are available from Bitmain’s official website and should be downloaded onto an SD card before inserting into a slot within your test fixture. The conversion file acts like an operating system for the chip while allowing it to boot properly during tests; meanwhile, the test file simulates various actions taken by miners when running and can detect any issues with signal transmission between boards or chips during testing.

With Putty installed and configured correctly, along with both conversion files and test files saved onto an SD card, you are now ready to begin testing with Bitmain’s Test Fixture!

Power Supply Requirements for Testing All-in-One Machines (Miners with PSU)

When testing all-in-one machines (miners with PSU, such as S11, S15, S17, S19, etc.), it is crucial to ensure that the miner’s own power supply is used to supply power to the test fixture and hashboard. The connection should be established correctly by using a 4-pin voltage regulation cable. This will help minimize damage to the mining equipment and promote overall system stability while testing. Additionally, all safety precautions must be taken when handling and working around electrical components and equipment.

Power supplies must meet certain specifications to operate efficiently and safely. For instance, the minimum input voltage for most ASIC miners is 10V DC; however, some models may require up to 12V DC. Additionally, the current delivered by the power supply must match the rated power draw of the miner being tested for optimum performance results. It is also crucial that an appropriate level of protection from short-circuit and overvoltage scenarios are provided during operation to prevent any potential damage from occurring.

In summary, when testing all-in-one machines (miners with PSU) with Bitmain’s Test Fixture, the miner’s own power supply must be used at all times. Furthermore, it must meet or exceed specific voltage requirements to ensure optimal test results while providing a safe operating environment for all personnel involved in the process.

Tips on Using the Conversion and Test Files Correctly

Using the conversion and test files correctly is essential when running Bitmain’s Test Fixture. It is vital to ensure that a suitable conversion file is selected for your miner model. An incorrect selection may result in an unexpected power supply abnormality or other issues. Additionally, it is essential to ensure the correct test file is chosen to properly simulate all of the actions generated by the miner while running and accurately detect any bad chips on hashboards. Here are some tips on ensuring the proper use of these files:

• Make sure the conversion and test files are always up to date. Bitmain regularly releases new versions for miners with various advancements technology, so it is important to make sure you are using the latest version at all times.

• When loading files onto an SD card, format the card before doing so. This will prevent any potential errors or conflicts from occurring while testing.

• Check the integrity of the files before running tests, as even a single byte discrepancy may lead to inaccurate results.

• Ensure that conversion and test files are properly configured for each specific miner model being tested. This is necessary to ensure the correct operation of the test fixture.

• Follow all safety procedures when handling and working around any electrical component or equipment. This will help to promote a safe testing environment for all personnel involved in the process.

By following these tips, you can guarantee accurate results while setting up and running Bitmain’s Test Fixture. Doing so will also help to ensure that the entire testing process goes as smoothly and efficiently as possible.

Troubleshooting Errors During Testing Process

Troubleshooting errors during the testing process is an essential part of ensuring the accuracy and effectiveness of Bitmain’s Test Fixture. To identify and address any potential anomalies, such as a sudden power supply abnormality or unexpected behaviour, users must be knowledgeable in both hardware and software requirements when troubleshooting. When addressing hardware issues, users must ensure the power supply meets or exceeds the voltage requirements of the tested miner and that all connections between components are secure. For software troubleshooting, users must verify that the correct conversion files and test files are selected for each miner model and that any settings related to temperature limits are adjusted accordingly. Following these tips will help to improve the user’s chance of success and minimize any instances of errors occurring during the testing process.


In conclusion, Bitmain’s Test Fixture is a powerful tool that can be used to accurately test ASIC miners and detect any potential errors or conflicts occurring while testing. To ensure accuracy with the results, users must take specific steps before beginning the testing process, such as following the safety procedures and troubleshooting any errors that may arise. By doing so, users can guarantee more accurate results while setting up and running Bitmain’s Test Fixture and ensure that the entire testing process goes as smoothly and efficiently as possible.
