Anyway, it seems that the TOC is red, i think could it be a protocol error. Speed of disc and time that spins, seems that the reading of the TOC is completed, maybe servo it's expecting some sort of response code from the controller...or the inverse, the controller is expecting some data from servo board
it's a real mystery. Yesterday I spent all day checking the schematic, PCB layout, checked the components one by one, plugging and unplugging wires etc... but nothing, it's ok for me, the PCB layout is the same as the wiring diagram which doesn't I can find errors. The only error I had encountered a few days ago was a capacitor, the C3 which was 22pF instead it had to be 22n but I immediately noticed it and replaced it. But I'm not giving up, I want to find the error if any. There will be a way, I think ... I accept advice thanks!
for example, it would seem to recommend the TDA1302, but what would be the differences between the TDA1300 and the TDA1302. For me none according to the datasheets.
that red line between pin41 SAA7372 and pin11 TDA1300, I don't understand what it means, a connection between the two pins?

result with HECD
if you want to analyze the file just download the software at the attached link, it's free.

what‘s the frequency of the XTAL you use for SERVO? 8.4672MHz, cause the OM5284 using this by default! Would you send me your schematics to check it?
the wiring diagram I used for the PCB is the one you sent me.
Circuit of the CDT-713.
Dear Sergio, I am working on an Audionet ART G2, based on Marantz CD63 or CD6000. As far as I can see the communication pins which are labeled AuxBack, AUX1 Data and AUX3STB on HECD-019A are labeled DSA ACK, DSA DATA and DSA STRB on the Audionet connector. Would your board support this kind of communication?

It seems to me that it is equipped with a SAA7345, so the mechanics should be a CDM PRO?
but I didn't understand what you would like to do, why do you want to use a Josaudio control? I also have a Josaudio control one but I have never managed to make the HECD-019 servo work in combination with Josaudio, surely the problem is the Philips P87C58 eeprom on the servo board, the axis commands are stored in this eeprom and they do not combine with the Josaudio controller.
I have bought the Josaudio one or two years ago, and now I found the time to test it. But first test was no success. I have found this thread and somebody to talk to (which is hard to do with chinese guys...), so I was hoping you have a better solution. I don't know why the caps are cut, I will check it tomorrow.
