HEX file to become programmed; the 2nd step: click hook up with hook up Usually; the third stage: click the program button, and after completion, click on verifiy to prompt the verification to establish that the programming is effective.
2. For The very first time utilize the 19 collection test fixture SD card flash method to update the FPGA control board with the tester, duplicate it to your SD card immediately after decompression, and insert the SD card in the fixture card slot: Electricity on for around 1 minute, and look ahead to the pink and green indicators to the Command board to flash three periods in succession, then the update is total (if It's not up-to-date, it may well cause a fixed chip to be documented as faulty in the course of the check).
7. When powering on the hashboard, consumer need to to start with connect the detrimental copper wire of the ability supply, then the good copper wire of the facility supply, and finally plug in the signal cable. When eradicating, the buy of set up needs to be reversed. Very first get rid of the sign cable, then get rid of the beneficial copper wire of the power supply, And eventually remove the damaging copper wire of the power offer.
Maintenance process: Check out the looks and measure the capacitance or resistance with the front chip. Usually, it really is brought on by poor chip welding or hurt and irregular resistance of a particular chip capacitor or resistor, or problems with the chip by itself;
③ Use a multimeter to measure the resistor of R8 or R9 to determine whether it is inside ten ohms, as well as looking through will never soar randomly. If not, swap both of those resistors;
If you have any dissatisfaction through the transaction or have precious strategies for us, be sure to contact us by using this e mail deal with:
a) In the event the Liquid crystal display Display screen ASIC NG: (0), initially measure the whole area voltage of 21V along with the Strengthen circuit voltage of 25V after they are typical. Then use a brief-circuit probe to limited-circuit the RO exam point and 1V2 check level among the main and 2nd chips, then run the chip finding program.
Almost certainly, the IP can not be discovered because of abnormal Procedure. Confer with the very first position for troubleshooting.
Servicing personnel will need to have electronic information, no less than just one 12 months of servicing practical experience, Purchase Here and proficiency in BGA/QFN/LGA packaging and welding technology.

6. After the repair, the hash board needs to go in excess of two times to be judged as a very good product or service when examined by the check fixture. For The 1st time, immediately after replacing the extras, watch for the hash board to chill down, use the examination jig to check the go, then established it aside to cool down. The next time, wait a couple of minutes for your hash plate to cool completely ahead of tests once more.
The strategy for repairing the issue is as follows: through the PT2 test, intently keep an eye on the serial port print log. If the serial port has become operating for an prolonged time period, use a brief-circuit probe to small-circuit RO and 1.
In summary, this repair approach entails examining Just about every chip in sequence by limited-circuiting them and checking the serial port Procedure until finally the defective chip is recognized and changed.
