I purchased a used c-dsp 6x8 and everything works great except the remote control. It is stone cold dead.
I've been able to upgrade the firmware on the main unit, but when it comes to updating the remote control firmware, I get a log.txt file on the sdcard with:
DSP settings file (*.bin) not found !
Panel firmware file found.
Failed to receive upgrade response.
I had a peek inside the remote control; anybody know what the jumper does? It also has a 5 pin header for programming. I have experience programming such an interface using a usb-uart programmers, for programming esp8266's for example. Maybe it can be reflashed?

Hard to say but maybe it's a faulty cable?

It seems to be a bad transceiver somewhere. I bought it used and it was a bad deal.
I've seen it work with a short 4 conductor cable, but not lately.
It's never worked with the 6 conductor cable that came with it and
it only worked briefly with a new 25' 6 conductor cable.

This is my problem and my solution is to bear it and buy a new c-dsp 6x8.
I can dump the old one on ebay as is; or maybe ship it back to HK for repair? If it can't be fixed for $100 then it's probably not worth it as I'd still be selling it used on ebay and I'd be lucky if I could get $180 for it vs. $80 as is.

Oh, this gets better. I connected the windows c-dsp 'plugin' application and while the app was up I was able to use the volume control. As soon as I closed the app, the remote control died again.

When I disconnected the usb cable, the remote started working again and is working w/ the 25' 6 conductor cable.
The original cable still doesn't work.
Was that normal behavior and was I an idiot when I ordered a replacement?

Did you contact our team about this (support.minidsp.com)? It would seem like purchasing the RIGHT cable (i.e. shipped with our unit) together with a new remote would be the first step we'd recommend. You might have too many unknowns here.. That's a 25' 6... like 25ft cable? That's extremely long... That's not a car.. Please provide more info so we can help.

I purchased a new 6x8. I will be putting the old one back on ebay.

It turned out to be a documentation issue, I think. If there is a usb connection, then the remote will not function.
The documentation is that switching profiles would not work if the plugin/app was in operation.
That was not my experience. So much as plugging in the USB, and the host detecting and connecting, disables the remote.
It doesn't matter if the plugin/app is running or not. I had exactly the same behavior with an 8' 4 conductor phone cord.

Glad to hear that you're all set now.. With regards to the remote, it's actually the switching of presets that won't work. The volume control will work fine. Correct? We do so to prevent the user to switch the preset while connected. Sorry for missing this info on the manual. Thanks for pointing this out!
