Thanks to the update and for taking your time to look into it

Thanks Burkhard!

10FT cable is all that I need for my home studio in this Covid-19 lockdown/no gigging.

The kaos.bin file was downloaded to my Macbook Pro and copied to each USB drive the same way in all tries to update the KPA Power Rack. If the file was corrupted all the OS versions was corrupted when copy and paste from my Kemper folder on my Macbook Pro to the same USB drive. I always eject the USB drive for safe removal of the USB drive to not loos any files. The SanDisk works for everything else. It might be that those hours I was trying to update the KPA OS something occurred that´s out of anyones control.

Thanks again for the update

Hi y´all!

Hope someone with a controller might help me out.

Just sold my non powered Toaster cause I got my hands on a Power Rack with controller. The thing is that the Ethernet cable is missing in the package and need to make one from bulk parts and cable, that I´ve got in large amount.

What I need is a pic of both ends of those RJ45 connectors with the locking tip turned away from the camera. Some systems cross the wires in the 8 wire cable, but it might be as simple as a straight 1-1, 2-2, 3-3 ........... 8-8.

Thanks for taking your time to post a detailed pick so I can follow the colour wiring before I press those RJ45 connectors, so I do not frie the internal RJ45 connectors on the KPA or controller.

Thanks for looking into it! I did get help on FB Kemper profiling amp / kpa user group earlier today.

I found one issue in the equation that was an eyeopener for me. I used a new SanDisk 32GB USB 3.0 driver. The KPA started to read the OS Update from the drive, but it failed on several updates back to OS 6.0. I startet to think of the KPA that´s about 9 years of age this year that the team used USB 2.0 protocol. I was right, and when I put the files on an older USB 2.0 driver the 7.1.5 went smooth, and I continued when the update was done.

My KPA Power Rack now runs FW 7.5.4.19312 and communicates with RigManager just flawless.

Love the KPA and will keep to it as I only got one tube amp left a 3rd Power Dream Solo 2 ´65 Blackface. Now I just need a KPA DI to profile the head.

Thanks for putting your effort out and help with tips and tricks.

Now I only need some tip/ trick on how the KPA RJ45 cable is wired as it did not follow the combo of 4U rack case, KPA Power Rack and Controller.

Any of you may confirm how it´s wired in both ends of the two RJ45 connectors? A close up pick in good light conditions would help me a lot as I`ve got cable and connectors in bulk and skills to make the cable.

Thanks again for taking your time offering a helping hand to all of us in need of tips and tricks to solve our issues. Much appreciated!

Best Regards from Norway.

Hope you all are well and safe!

I just got me a 2nd KPA, but a Power Rack this time. Current FW is 5.2.0.12879.

Q1: How to update Firmware while the KPA doesn´t read the Update File from the formated USB-stick? How may I force the KPA to read the Update-file?

Fact: I´m selling my unpowered Toaster to it´s new owner tomorrow . The display on my KPA Power Rack reads USB-stick as External Storage, and would not read the OS Update file (the USB-stick has been formated by the KPA Power Rack.

Q2: Is there a safe way to go around this to update the FW 5.2.0.12879 to 7.5.4 ?
I´m not able to communicate with the KPA Power Rack other than changing it´s name to the same as the Toaster. Toaster has been unregistered on my Kemper Profile sign in, while the Power Rack is registered.

Fact: I can not find all the 244 profiles from the KPA on the USB-stick even though I have copied profile by profile the manual way.

Q3: Is it possible to update the KPA with the new FW from the USB-stick while turning the KPA on and holding down two buttons? I found a thread, but the person was not sure witch buttons to press while turning the KPA to tuner.

All help appreciated - Thanks!!!
