Make use of the take a look at fixture of the V2.2010 Command board. The constructive and unfavorable poles on the test fixture have to be put in with discharge resistors. It is usually recommended to use a cement resistor of 25 ohms and a lot more than 100W.
When there is Phony welding, it must be re-soldered. When there is problems, it ought to be calculated whether the resistance benefit is standard. Change the corresponding elements abnormally, and Examine the smaller board soldered about the PCB; the compact board is revealed within the figure below.
HEX file for being programmed; the second action: simply click "hook up" to attach Generally; the third stage: simply click the "method" button, and immediately after completion, simply click "verify" to prompt the verification to verify which the programming is effective.
8. To interchange a fresh chip, printing pins and soldering paste are needed to make certain that the chip is pre-soldered after which soldered to the PCBA for repair
3. If the PIC sensor NG is displayed over the Liquid crystal display display of the hash board tester as well as the test study temperature is abnormal, then Stick to the steps below to troubleshoot: A) Test if the 4 resistors of R24~R27 are welding abnormally, and Check out whether or not the welding of PIN2, three of U3 is regular; Determine 5-13 B) Verify whether or not the 4 temperature senses U4, R28~R30, U6, R31~R33, U7, R34~R36, U8, R37~R39 along with the matching resistance welding are irregular, The placement on the temperature feeling is shown in Determine 5-fourteen, the temperature sense is all Situated within the again from the PCB, the resistance is found about the front with the PCB, and whether the temperature-sensitive three.3V ability source is typical;
If the miner however loses hashrate, lessen the frequency along with other conditions stay unchanged. Let the miner mine to check out if it's going to get rid of hashrate and whether the hash board will hit X. If it nonetheless hits X in shedding hashrate, then take out the warmth sink of the hashboard for mining and look ahead to the hashrate to drop.
If there is absolutely no three.3V output, Examine the connection position from the hash board tester cable as well as the hash board.
Check the welding high-quality of the warmth-delicate chip along with the little heat sink. The deformation of the massive warmth sink materials will induce lousy warmth dissipation of your chip and impact the temperature change.
Continue on to investigate Look Here with dichotomy until eventually the problematic chip is discovered. Assuming that there's a trouble Using the Nth chip, once the 1V8 and RO among the N-1th and Nth chips are small-circuited, N-one chips are available, but if the 1V8 and RO concerning the Nth and N+1th chips are brief circuited, the complete chip can not be uncovered.
The supporter will alarm and it will not perform Commonly. Usually, the ambient temperature is simply too superior, and also the abnormal operation of the fan may also trigger abnormal temperature.

If your voltage benefit has a big deviation, Review it Using the calculated worth of the adjacent group to determine The problem.
d-1) The initial case: the exam time is largely the same as The nice board (ordinarily the value of X will not likely improve every time you test) (check time refers back to the time from when the beginning check button is pressed to some time when the result of ASICNG: (X) is shown on the Liquid crystal display).
Refer to the voltage benefit range described through the signal trend. Should the measurement encounters a significant deviation on the voltage price, it could be as opposed Along with the measured value of the adjacent team to determine.
