Oscilloscope. The proposed model is UTD2102CEX+. A community cable is needed for an Connection to the internet and also a secure network.
1. Listen to the technique when replacing the chip. There will be no obvious deformation of your PCB board right after changing any extras. Test whether you will discover any open up or brief circuit issues from the alternative sections and bordering sections.
Before testing the pattern, the repaired hashboard must awesome down ahead of tests; otherwise, it will cause testing NG.
In keeping with this process, discover the chip that also has the long-tem operating failure soon after a certain chip is brief circuited. Usually, it truly is due to a certain chip damaging, so just switch it; Determine 5-19 7. Phenomenon: PT1 chip examination is Alright, PT2 operate examination often studies a certain chip NG.
8V and 1.2V patch filter capacitors are small-circuited, or perhaps the IC on the LDO circuit in this area has weak soldering/Untrue soldering/substance hurt;
d-2) The 2nd circumstance; the exam time is nearly two times as long as The nice board (occasionally the value of X will alter each time you exam, and in some cases X=0); at this time, the log usually has the next information and facts (the red amount is just not thirteen sometime, dependant upon which seat the hashboard tester is linked to); in the exam, assume that the domain voltage of each of the fields in front of the abnormal posture is nearly below 0.
Verify the instruments to make certain that the check fixture can do the job usually. Determine the parameters of the upkeep station exam software package, the Edition of your exam jig, as well as other relevant parameters.
Repair process: Using the dichotomy approach, small-circuit the 1V8 examination issue plus the RO exam level in between the 38th and 39th chips While using the shorter circuit probe. If the log can find 38 chips, there's no dilemma with the primary 38 chips; if small-circuiting the 47th chip, nevertheless the log reports forty sixth, it implies that the 47th chip cannot be detected, and there is no issue with the Visible inspection. Normally, the 47th chip shall be replaced;
Windows mining Our mining monitoring and management software program for Home windows GPU rigs is the ideal Alternative for individuals who choose to mine on their Windows machines.
Checking out the serial port log, if 0 chip continues to be discovered right now, It'll be among the following situations:
6. Following the repair, the hash board must move more than two occasions to become judged as a fantastic solution when tested via the exam fixture. For The 1st time, immediately after replacing the accessories, watch for the hash board to chill down, make use of the check jig to check the pass, and afterwards set it apart to chill down. The next time, wait a couple of minutes for your hash plate to chill absolutely right before testing all Go Here over again.
By bringing their particular machines, participants can figure out how to fix up to five damaged devices through Every session, generating the journey pay for itself. Don’t Allow complex aspects keep you back.
d-two) The 2nd case; the examination time is almost twice as long as the good board (from time to time the worth of X will change each time you examination, and from time to time X=0); presently, the log usually has the subsequent info (the pink selection is not thirteen, depending on which seat the hashboard tester is linked to); in the take a look at, believe the area voltage of all the fields before the abnormal posture is sort of a lot less than 0.
4) No hash level soon after running for the time period, mining pool connection is interrupted: Check out the community.
