3. Connecting the hash board to the tester
It is important! When working with the tester, it is allowed to use ONLY LINES and adapters FROM THE DELIVERY SET! Or self-made in accordance with the pinout provided by STASIC tech.
ATTENTION! The hash board must be de-energized before connecting and disconnecting the tester.   ALGORITHM FOR CONNECTING HASHBOARD TO TESTER:

 

 

  1.  Connect signal cable of tester to hashboard.
  2. Connect power supply (+\-) to hashboard.
  3. If tester is powered not from adapter, but for example from a USB computer or other device, then it must be grounded.
  4. The laboratory power supply (for powering hashboard) must be grounded.

ALGORITHM FOR DISCONNECTING TESTER FROM HASHBOARD:

  1. Turn off the hashboard power (+\-)
  2. Disconnect the tester signal cable from hashboard.

All of these steps will minimize the likelihood of exposure to potential differences between devices and eliminate the risk of damage to the tester.

  A)   Connect STASIC (20 pin) – Bitmain (18 pin) cable, supplied with the tester (on the example of the Antminer S17 board) B. Supply appropriate power to the hash board. C. We go to the user interface, update the page (http://5.5.5.5/menu), select the hash board model in the browser. D. Select the correct model for diagnosis.

Chip voltage reading function Whatsminer

 

ATTENTION! for function to work, required power supply for hash board is 12-14 volts, 25 amperes,
A laboratory power supply is being used! PSU ASIC IS NOT SUITABLE!

 

When you press “Read Temp” button for first time, temperature of each chip is polled; when you press it again, information about voltage of each chip is displayed. The function helps diagnose Whatsminer malfunction – “Loss Balance”

The latest Whatsminer Chip Status Survey system from STASIC tech®

 

When diagnosing a Loss Balance error, you should pay attention to the voltage readings; on a fully operational board, the voltage readings will be in the same range. If you notice a difference of 90 mV or more, you should pay attention to it. We also conduct tests at different temperatures of the hash board, from room temperature to operating temperature of 60-70 degrees.

Hash calculation testing function (hash test)

 

ATTENTION! for function to work, required power supply for hash board is 12-14 volts, 30-75 amperes
(depending on board model and number of chips),
a laboratory power supply is being used!

When performing this test, monitor temperature of hash board, maintain same temperature of hash board each time you press HASH TEST button.

 

ATTENTION! If, during tests, hash board shows all chips in red, measure voltage at hash board terminals at time of test; it should not be lower than required (12-14 volts). If voltage sags, check whether your power supply is suitable for test or eliminate loss on wires by using a short wire of required size for current used

Antminer 17/19 series chip initialization function

 

ATTENTION! for function to work, a laboratory power supply is being used! PSU ASIC IS NOT SUITABLE!

 

The initialization function performs a procedure for checking readiness of chip core on hash board, similar to operation of ASIC control board before starting frequency overclocking process and starting mining process. Initialization is carried out on a completely repaired board on which, during a standard test in “START TEST” mode, all green chips are displayed, and temperature sensor readings are also correct. The function is started by pressing “READY CHIP” button

Hash calculation testing function (hash test) Antminer 17/19 series

 

ATTENTION! required current for the function to operate, 30-65 amperes
(depending on board model and number of chips),
A laboratory power supply is being used! PSU ASIC IS NOT SUITABLE!

Before performing a hash test, you must select frequency of chips by pressing “OVERCLOCK” button, each press increases frequency. To run one hash calculation test cycle, you need to click “HASH TEST” button.

When conducting this test, monitor temperature of hash board, remember that each time test is run, board consumes from 30 to 65 amps!

Maintain same temperature of hash board every time you press button “HASH TEST”.

If the board is severely overheated, some chips will appear red with a hash value of zero. Do not overheat the hash board by pressing the button frequently “HASH TEST“

 

ATTENTION! If hash board shows all chips in red during tests, measure voltage at hash board terminals during test, it should not be lower than required for hash board model being tested. If voltage drops, check power supply to ensure it is rated for testing, or correct loose wire by using a short wire of correct size for test current used.
