c8051f340 usb bootloader Jovy Systems RE8500

[okraglaczek]

Hello,
I recently bought an Jovy RE-8500 station (almost new) for my workshop. I like the rework station. It's a shame that the manufacturer no longer exists.
The station has a couple of minor defects. The laser does not work, the vacuum tweezers are weak. It's all fixable.
The reason I am writing to you is. Is it possible to read the firmware from the C8051A340 Controller?
From the memory of 24C64WP, I think I can read it. But the C8051 is problematic.
If I have already opened the control box, then I think to make a backup copy in advance in case you have to repair it.

I have Silicon Labs USB Debug Adapter and Silicon Labs for C8051xxxx, but I can not find the read function.
PCB Rev.: 2.03
Maybe someone has already done this? Or is there already a dump so that I do not risk in vain?
And what about activating license for a computer control software? Can I get around it somehow?
Regards
Tudor

Thanks for the answer.
I have tried all versions from this site.
Also with changed the IP address to French. Everything exactly the program is launched as not licensed.
I even received a license file from the sellers archives with the correct serial number. Everything exactly the program is launched as not licensed. I think that he did not send me a fake.
Why is this so?
Please help me.

Okay so the bottom heater has an integrated thermocouple which does not show any ohms does anyone know how I can check it is elstien T-SHT 600 watts

You can chek the elstien T-SHT 600 with the simple ohmmeter. The heat spiral must have several ohms. Approximately until 10 Ohm. If the resistance is very high, then you must check the connecting the spiral with a further wire.

After using a firmware with Silabs bootloader there is a problem with connection using Jovy PC Suite. Problem is caused by unoriginal bootloader, app try to get serial number from bootloader area and convert it to number what trows exception because data is rubbish, not a serial number.

So, I patched original .exe to use file sn.cfg as a external source of serial number. Without this file app will use hardcoded serial number for RE-8500 rev 1 with 5 TC. If you want to use with 3 TC version(serial number above JV85114013) or RE-7500 you should provide valid SN in config file. Licence files are not longer needed.
