The LDOs in domain 1 to domain 16 can be used universally. They are the low voltage LDOs.

The LDOs in domain 17 to domain 21 can be used universally. They are the high voltage LDOs.

But the low and high LDOs can not be exchanged.

Check the BTC tool software version, it should be the latest one.

Check the network. Replace the router and switch.

Do SD card flashing and then update to the latest firmware.

This shows it is normal. It needs to upgrade to the latest firmware version.

Request the customer service for the S9 firmware for flashing the card.

To avoid immediate infection after flashing, it is necessary to set up a separate network and then upgrade to the latest antivirus firmware. If that doesn't work,replace the control board's flash memory.

Level 3, Level 4 each level has different frequency and voltage.

The high and low levels depend on the configuration file installed into the tester.

Hashboard crashes. Check the signals.

Test another hashboard with tester to confirm the tester is OK.

Possibility

1. The connector is too dirty.
2. The data cable brokenhas problem
3. The signals are abnormal. Test with tester.

• Check the domain voltage,it should be above 10V.
• Check the RI signal and RST signal.

• Check the domain voltage,it should be above 10V.
• Check the RI signal and RST signal.
