Problem with my Dynacord DSP 260

Postby jedg » Sat Feb 02, 2019 5:29 pm

Hello

I have a problem with my DSP260.
After a longer break in use (1-2 weeks), Bootloader1.2.0 appears on the screen. I upload the latest program by DSP-260_Editor_V1.5.1 and everything is OK.
After about 1-2 weeks, the Bootloader inscription again appears on the display.
Please help.

Sounds like a dying CMOS battery to me......

When it's plugged in it gets a little boost, enough for a few days but then sags to the point where It is no longer to maintain the 'non-volatile memory.

Have a look in the used guide, they're may be advice on how to change it.

I would suspect that the updated software is held in battery-backed memory and that the battery is dead or almost dead. I don't know how old the unit is, but with RS-232 comms, it can't be that new.

So it's probably a case of opening it up, looking for a battery and replacing it.

Great minds Wonky :thumbup:

edit :- a quick shift through the manual reveals no mention of a battery of any troubleshooting strategy.

Thank you for your response.
Unfortunately, but I've already opened the processor and found no battery. I know a little bit about electronics and I know that the battery can have different shapes and I have not found anything like it.
DSP is over 3 years old and unfortunately is no longer under warranty.

It may well use a capacitor to keep the memory intact, but without a circuit diagram, it's impossible to say. I'd contact Dynacord directly and ask them. They are a high-quality manufacturer and may well offer to have a look out of warranty.

Welcome to the SOS forums, Darko... but if youw ant to be taken seriously rather than as a spammer, it might help to explain what you think the problem is and how you might be able to fix it so generously...
