II. Hash board tester operation guide

In this test, we take the S17 hash board as an example to explain the operation. After selecting the S17 hash board, press the white button to enter the S17 analyzer page, as shown in the figure below:

In the picture above, we will see the name of the selected hash board, the link port of the tester, and how the different keys work.

The thin blue line on the screen of Note2 indicates which interface of the tester must be used to connect to the selected hash board. Note 3 represents the working methods of different keys.

1. Antminer hash board

In the picture above, we can see the working status of each button in Note3, as shown below:

PSU: Press the PSU button to enable S17 PSU (APW9 with 19V), we need to use a PSU cable to connect the tester and PSU.

MOD: Select the test mode by pressing the MOD button. S17 has 2 test modes: Mode 1 and Mode 2.

ONE: If this button is toggled, it will change to 999. This means how many times we want to test the hash board. Once or repeat 999 times.

PIC: If we toggle this button, it becomes PC0 and PC1. If PC0 is selected, the tester enables the PIC microcontroller in the hash board, turns on the MOSFET in the hash board, and makes the current flow into the hash board. In this case, the RST signal remains at 0Vv in the hash board. If PC1 is selected, the PIC microcontroller in the hash board will be enabled, but the RST signal will remain high (1.8v on the test point). If we choose PIC, it will turn off the MOSFET in the hash board.

Note: If we select PC0 or PC1, test the hash board with the 999 option; the PIC of the selected hash board will turn on as long as we test it. Otherwise, PIC will be turned on and off for each test.

Back: If we press the back button, we will return to the page where we selected the hash board.

TEST: After adjusting the PSU, MOD, and ONE options, we can press the TEST button to test the hash board.

After testing the hash board, we will see the following test results on the screen:

Note 4 indicates how many times the tester has tested the hash board;

Note 5 indicates how many chips the selected hash board should have under healthy conditions;

Note 6 indicates how many healthy chips the tester has detected from the first ASIC to the front.

Note 7 indicates how many healthy chips the oscilloscope has detected from the last ASIC to the reverse signal test point of any chip connected by the oscilloscope probe.

Note: We must connect the + pole of the oscilloscope probe to the RI/RO (Antminers) or TX (Whatsminers) signal of any chip, and connect the negative pole of the scope to the negative pole of that chip)
