Why use an Antminer s19 hash board ASIC repair test tool?

Antminer s19 hash board ASIC repair test tool.

A test fixture or test jig is a device that is used to test hash boards, especially the Antminer s19 hash board. S19 test fixtures are often made from a control board of an S19. This is done by uploading a test jig program onto a micro SD card and inserting it into the micro SD slot on the control board. Small displays are also usually added to provide information during testing and a button to easily start the testing process when needed.

Using a Test Fixture. To use a test fixture during Antminer s19 hash board diagnostics, first connect a USB to TTL cable to the fixture and plug it into a computer or laptop. Run a program such as xshell to connect to the fixture. Then plug power into the fixture and turn it on. Next, attach an I/O cable between the fixture and the hash board that is being tested. Connect power to the hash board and press the button on the test fixture to run the test.

Test Results. Now that the test has been run, results can be observed. In the log on xshell there will be lots of information, including how many ASIC chips were recognized. This is a very useful piece of information, as it can tell you which chip is causing problems. For example, the test fixture could only pick up 32 chips. This doesn’t necessarily mean that chip 32 is the problem, but there is a good chance that it is chip 31, 32, or 33.

When fixing hash boards, test fixtures are a vital tool that helps to diagnose the problem. When it is a problem with one of the ASIC chips, a test fixture can tell a user which chips are most likely to be causing a problem.
