b) If 1 chip are available in stage a), it implies that the 1st chip as well as the prior circuit are usual. Use a similar method to check the following chips. One example is, In case the 1V2 take a look at position and RO examination place amongst the 38th and 39th chips are brief-circuited, In case the log can find the 38th chip, then there isn't a trouble with the very first 38 chips. If 0 chips remain found, first Check out whether the 1V2 is ordinary.
5) After functioning for any timeframe, there isn't a computing power, the relationship to the mining pool is interrupted, then Look at the community;
; Next, once the visual inspection is handed, the impedance of each and every voltage domain can be analyzed first to detect whether or not there is a short circuit or an open circuit. If located, it need to be dealt with to start with. Furthermore, Examine whether the voltage of each and every area is about 0.36V.
As proven while in the figure down below, the first hash board has no hash price just after operating for approximately three minutes.
9. When replacing a new chip, cleanse the pins and implement solder paste to make certain the chip is coated with tin just before soldering.
(two) If the looks of the chip just isn't destroyed, just exchange the chip with the lowest reaction level in each domain;
This hash board is effectively-produced and is apparently developed to previous. It provides steady efficiency and suits my mining products beautifully.
(1) A sudden ability outage or lower than 30 seconds all through the process of opening OTP will trigger the Regulate board to are unsuccessful to open the OTP operate plus the Regulate board will never get started (not hook up with the world wide web).
two. Growing old check: During the growing older test, repair must be carried out according to the monitored interface examination, which include:
Evaluate no matter whether There is certainly output on the second pin Purchase Here of U3 along with the voltage is about 3.3V; if yes, be sure to carry on to troubleshoot the condition; if there isn't any three.3V, make sure you Test the link position on the hashboard tester cable along with the hashboard is Okay, and reprogram the PIC.
two. Make the check SD card In keeping with the requirements, and right unzip the compressed package deal of The only-sided warmth sink inspection chip to produce the SD card;
three. The check SD card will be manufactured Based on the necessities, along with the double-sided warmth sink eight-occasions Patter take a look at has to make an SD card, as revealed within the figure underneath;
A short while ago, a lot of firms declaring being mining businesses imitate us and say that they are related to us, or that they are our department companies, which has induced customers to get deceived.
a) Liquid crystal display Show ASICNG: if (0), first measure the total voltage of the measuring area as well as Strengthen circuit 19V is usual, after which you can utilize the limited-circuit probe to limited-circuit the RO examination level and also the 1V8 take a look at place amongst the primary and the second chip, after which you can run the program to locate the chip.
