This thing is a pile of cr@p, a ripp-off, i warned people here and i can see that the story still goes on. It's time to put it on Ebay. |

If there is any sort of interest, i could be motivated to publish the psu design files (not that great, as it was built around components i had around) and some infos on the isolation mod. --- End quote --- Robert - could you please specify the type of digital isolators you used for linking between control and signal section of the HDG? I expeimented with a similar configuration as you reported and used two ADuM2400CRW but didn't get the link to work. A closer look at the footprints suggests that the aformentioned digital isolator will work for U14. But U13 might be a different thing since Ve1 is connected to the 3.3V rail which might imply that it has at least one data line in reverse direction. Another look at U14 and the way channel "D" is left unconnected may indicate that both isolators are supposed to be ADuM2401CRW (3F+1R channel arrangement). How did you get your digital isolation barrier to work? Thanks, Thomas --- End quote --- Im looking it up this evening. I have to open up the whole thing anyway, as it suddenly decided to be a HDG2002B again. I have no idea what has happened now, but it has un-hacked itself... |

Try to make a sweep and look to signal amplitude, try to modulate a signal and see what you obtain, try to use the noise function and see what you get, try to set screen brightness and other things and see what happens when you recycle the power.... If also the PSU it's a petard, well ... This thing is useless, it's a scam, sell it on ebay and save money to buy something else. I did and i started to work around my things not around this cr@p. |

I have model with PCB 1004.1, SW 1.00.3.03.05 (150819.0), Kernel 3.2.35, FPGA 42, Keyboard 3. The first time in my life I edited in Linux and has become :palm: I damaged the contents of a catalog system/root. Someone from colleagues could send the catalog root? PS I read device data before damage |
