Numark NS6 Usb problem

[falcontech]

Hello
I have a problem with this board, it is the main board of the numark NS6 controller, the board has already undergone a repair, the two components highlighted in the photo have been replaced, the larger chip which is a CS5368-CQZ of the cirrus logic burned in continuation due to the breakdown of the smaller chip which is a voltage regulator (Ap1510) which instead of 5 volts supplied 12 volts and burned the CS5368-CQZ. Solved this problem I tried to connect it to the PC via USB but not by signs of life, so it is not detected by the computer, I state that the controller turns on regularly. I would be grateful if someone could help me, replacing the card costs more than 300 euros and it's not worth it. I enclose a photo of the card and the service manual of the controller. Thank you

I see the "+5VA" rail also powers the Atmega162 that connects directly to the ISP1583 USB interface. What're the odds that's thoroughly toasted as well?

Re: Numark NS6 Usb problem

Do you think both of them are burnt? What do you advise me to do?

[falcontech]

Re: Numark NS6 Usb problem

I read that the atmega162 is a chip that needs programming, I suppose it contains the controller firmware, if I replace it, how will I reprogram it later?

Re: Numark NS6 Usb problem

Well, they're both supplied from the same source, and the codec chip got burnt, soooo....

And yes, the ATmega is a pretty widespread microntroller. Probably the easiest way might be with a USBasp adapter.

Re: Numark NS6 Usb problem

so what do you recommend to replace both? or do I try to replace them one at a time?

Re: Numark NS6 Usb problem

Well, without the firmware for the ATmega, i'm not sure how far chip-swapping will get you.

Re: Numark NS6 Usb problem

yes I understand what you mean, in fact I would like to replace the usb chip first

Re: Numark NS6 Usb problem

Go right ahead, but it's more certain the ATmega is toast; the usb chip is just a "maybe".

Re: Numark NS6 Usb problem

I hoped it was the other way round, the thing about having to load the firmware unnerves me enough I don't think it's an easy operation, also because I don't know where to find the firmware, it is not downloadable from the numark website but it is updated via serato itch

Re: Numark NS6 Usb problem

Can you recommend a usb programmer for atmega169? the connector on the board has 6 pins

Re: Numark NS6 Usb problem

Well, since you asked...

Re: Numark NS6 Usb problem

ok but I would like a model that is right for me, there are many and I would not want to make a mistake in the purchase, I don't know if everyone can program the atmega169 and many have 8/10 pins and not 6 outgoing

Re: Numark NS6 Usb problem

The number of pins is less relevant than the signals they contain

Re: Numark NS6 Usb problem

I saw that there are also 10 to 6 pin gearboxes, but are all of them capable of programming atmega162?

[falcontech]

Re: Numark NS6 Usb problem

sorry but for me it's a new topic, I've never fumbled with these things

[falcontech]

Re: Numark NS6 Usb problem

I read that the isp1583 usb controller works with 3.3 volts voltage while the atmega162 with 5 volts so it is more likely that the latter has jumped since the 5 volts got high on the card

look on ebay for "USB-ASP"
cost about €2 but you want the 6pin>10pin adapter with it - so probably €3-4

software to use with it is AVRdude

Thank you
does anyone have the firmware of this machine? I can not find it anywhere, if I do not find the firmware it is useless to do the whole operation, I repeat the firmware of these controllers you can only get through you update with serato itch, if someone is in possession tell me thank you

Re: Numark NS6 Usb problem

if you had the programmer, you could try talking to the atmel to see if it's dead or not.
