Having problems with SCPI commands.
Resulting timeout error:
* Error!!!
VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

Is that with the USB key?
What's your firmware version?
If I remember correctly, the SCPI implementation is quite picky and I also ran into plenty of timeouts while exploring the undocumented SCPI commands.
Houseman:
Thank You chicken.

Sorry what do You mean by that?
If it has a USB slot on the back?
Mine is just a DSG815 (no model A)

So what did you do to overcome this timeout? Did you manage get into factory mode?
Best regards and thanks

To enable factory mode you need to insert the USB key/drive prepared with the magic data as described in the original post. The firmware does look for this key when changing modes.
I didn't explore much further than enabling factory mode and seeing the extra menus. Most of my reverse engineering was done by analyzing the firmware files. From my notes, it looks like I also only got timeouts for :SERVICE:READ:FLASH.
Timeouts probably indicate missing or invalid parameters, or that the SCPI client reads the data in the wrong way, or that the feature is not implemented or broken. Attached a spreadsheet with all SCPI commands I've found with some notes.

I still have 01.06, so there may be differences.
Houseman:
Thanks. Yep, the prepped key has been inserted but with all that timing error I do not know where the fault could be.
Do you know any limitation about USB pen size? I mean I have a 8Gb FAT32 format. Maybe it's too big?
By the way thank You for pointing out and helping me.
One last question: what kind of protocol/program did you use by sending commands to the DSG? Netcat? Ultra Sigma? thank You again
tv84:
Change USB pendrive. These equipments are extremely picky regarding USB pendisks.
Big size isn't better... it forces extra timings recognizing/validating things and that may crash against the timings of the internal software.
