b) If a single chip are available in move a), it ensures that the initial chip plus the earlier circuit are normal. Use an analogous technique to examine the next chips. Such as, Should the 1V2 examination place and RO take a look at level amongst the 38th and 39th chips are quick-circuited, Should the log can find the 38th chip, then there's no problem with the main 38 chips. If 0 chips are still located, initially Examine whether the 1V2 is standard.
Open MPLABIPE and choose unit: PIC16F1704, click energy to pick out the ability supply manner, then click run. The first step: choose file to locate the .HEX file being programmed; The second move: click on connect with connect Ordinarily; The 3rd action: click the program button, and following completion, click on verifiy to prompt the verification to prove the programming is productive. Figure five-7 Figure five-8 Forth step: Look at the Enhance circuit output
The voltage of each voltage domain is about 0.32V. If there is 16V power offer, frequently it's got area voltage. The priority is provided to evaluate the output of the facility source terminal on the hashboard and Test whether or not the MOS is brief-circuited (measure the resistance concerning pins one, four and eight). If 16V has ability source but no area voltage, go on to check.
a) Liquid crystal display Display screen ASICNG: if (0), initial measure the entire voltage of the measuring area as well as the Strengthen circuit 20V is normal, and after that make use of the small circuit probe to small-circuit the RO exam issue and also the 1V8 test point in between the very first and the 2nd chip, and after that work the program to find the chip. Look at the serial port log, if 0 chip remains to be found right now, It will likely be considered one of the next scenarios: a-1) Utilize a multimeter to evaluate whether the voltages in the 1V8 and 0V8 exam points are one.8V or 0.8V. Otherwise, it signifies which the one.8V or 0.8V LDO circuit of this area is irregular, or The 2 ASIC chips of this domain will not be soldered effectively; most disorders of this phenomenon are caused by limited circuits of 0.8V, 1.8V patch filter capacitors (measure the resistance on the patch filter capacitors relevant to the back and front in the PCBA). a-two) Verify if the circuits of U2, U3 and U4 are irregular, such as resistance welding, etcetera. a-three) Evaluate the resistance of R232 or R233 using a multimeter to check whether it is in 1 ohms as well as reading through will not jump randomly. Otherwise, you should switch both of these resistors. a-4) Verify In the event the pins of the very first chip are soldered nicely (it was identified for the duration of repair that the pins are tinned observing within the aspect, even so the pins are usually not stained with tin at all once the chip is removed). b) If a person chip are available in phase a), it indicates that the very first chip and the past circuit are excellent. Use a similar system to examine the subsequent chips. For instance, short-circuit the 1V8 take a look at place and also the RO examination position in between the 38th and 39th chips. If your log can discover 38 chips, the main 38 chips don't have any problem; if you still locate 0 chips, Look at the 1V8 very first; if It truly is normal, it means that there's a challenge Along with the chips following 38. Keep on to analyze with dichotomy until finally the problematic Buy Now chip is observed. Assuming that there's a trouble With all the Nth chip, in the event the 1V8 and RO concerning the N-1th and Nth chips are brief-circuited, N-1 chips can be found, but when the 1V8 and RO concerning the Nth and N+1th chips are shorter circuited, your entire chip can't be identified.
a) Liquid crystal display Exhibit ASICNG: if (0), 1st measure the total voltage of your measuring area plus the Increase circuit 20V is regular, and then make use of the short circuit probe to shorter-circuit the RO examination place along with the 1V8 exam issue amongst the first and the 2nd chip, after which run the program to discover the chip.

Test the welding top quality from the chip which connects sensor plus the small warmth sink. The deformation of huge heat sink materials will cause very poor warmth dissipation from the chip and influence the temperature difference.
The Antminer S19 is a powerful miner, but its general performance could be hindered by faulty hashboards. By replacing them with our upgraded hashboards, you may make certain that your miner is often working at its utmost prospective.
① The specific Evaluation technique is as follows: Very first, conduct only one-board PT2 test to examine whether or not the efficiency on the hash board is ordinary.
seven) A person hashboard has lower hashrate: As for this example, you could log in to the IP through the Putty application to look at if the domain working voltage of this board is normal and whether or not the NONCE return is ordinary. You are able to repair it In accordance with Putty LOG prompt.
Be part of the worldwide Local community of miners who belief minerstat to elevate their mining game. Will you be wanting to unlock your mining prospective?
If the voltage benefit has a significant deviation, Look at it Using the calculated value of the adjacent team to determine The problem.
six. Determine the upkeep station item and the corresponding test computer software parameters and take a look at fixtures.
Check with the voltage benefit vary explained by the sign craze. If your measured voltage value is simply too big, it can be as opposed While using the calculated values of adjacent groups for judgment.
