The Rigol DS1052E
Simon:
you don't need any programming experience for the mod, if you read back to near the beginning of this thread you will find me asking a lot of dumb questions and a lot of information on the mod including full instructions. all you need is a pc (win XP as the M$ dodo's took hyperterminal off vista - or use a freeware hyperterminal program) and a straight serial cable - ie: not a crossed or null modem one. of course as it has emerged later there are other considerations so beware and don't hold me responsable but my scope works just fine
rossmoffett:
If you don't have a serial cable, especially a rare female/female one, what I did is just wire from pins 2, 3 and 5 on the Rigol to pins 2, 3 and 5 on the PC. I used some female pins we had for cable-making, you could also probably safely use heat shrink to temporarily make contact with a wire end. You can't make it longer than about a meter though, or you can expect failures due to noise.

@dimlow and shafri
I believe the solution for you could be to dump binary file with correct data to serial port (e.g. with realterm). The idea is to rewrite corrupted fields in the same way how they got corrupted, i.e. :INFO:MODEL <correct bin data> <LF>
When I have time, I'll do some tests and let you know if this could be the way...
@bushing and especially shafri
JTAG: Please do not do any experiments with JTAG interface unless you exactly know what you are doing. You need to know CPU's surroundings very well before you can make use of it. As the attached flash exceeds cpu's address space, some signals are generated inside Lattice CPLD. You won't be able to read the flash unless you know how. Easier to use external programmer at this point.
@bushing
JTAG/SPI: The SPI PCB-connector is quite new to Rigol scopes (only some recent scopes have it) and there is need to write more unit-specific data into flash than just model and sn info (what commands allows you). That's the reason why they must use JTAG in final phase of production...
Could you upload 02.02.04 firmware somwhere?

Hi Simon
I am aware of the serial link method, in fact that was the reason to buy the scope. I was ready to take the serial way until the 'other considerations' you are mentioning appeared. From that moment I've just checked that my scope is able to be softmodded via rs232 and stopped because I really do not need the additional features by now. But just as an alternate way to avoid f*cking whatever I am just asking/suggesting if making a proggie that sends the strings as ultrascope send commands could be a safer way.
In any case the 'old' method documentation, including David's video is well kept in a directory of my HD for when it can be needed.

well mine went off without a hitch but if your in doubt then hold fire till you want a fasrer scope
