①DC 12V input

When testing the split-type Miner (such as T9+ S9 S9i S9j S9k S9se), you can supply power to the test fixture through this interface without connecting to the 6pin interface of the PSU.

②PSU 6pin connector
When testing the all-in-one Miner (such as S11, S15, T17, S17, S19, T19, etc.), you need to connect this interface to supply power to the test fixture, and at the same time connect the 4-pin voltage adjustment line of the original Miner PSU.

③Data line IO interface
It is used to connect the hash board. If you need to test T9+, you need to add a T9+ adapter board to complete the adapter from 18pin to 24pin.

④Serial connector
Used to connect to a computer USB via a USB to TTL cable to view the test log on the computer.
The wiring method is:
R=green
UART=black
T=white
Do not connect the red wire

⑤ Voltage regulation line interface

When testing the all-in-one Miner, the 4pin cable used to connect the original PSU.
