Hello I changed my keyboard for one ordered on Aliexpresse, the new keyboard is shipped quickly, well protected by a polystyrene box. The quality seems inferior to the original fluke keyboard, but everything works perfectly again. https://fr.aliexpress.com/item/1005004649936018.html?gatewayAdapt=glo2fra Thanks to feedback.loop for his help |

@timeandfrequency Why is it so difficult? Scope -> ON OC4USB/PM9080 & COM: 1200;N;1;8;N. QI 11 (QI_space_11)-QUERY INSTRUMENT = S/N |

Hi asis, --- Quote from: asis on January 18, 2023, 04:02:30 pm ---Why is it so difficult? [...] --- End quote --- Because I asked a few guys who repair scopemeters on how to proceed to catch the serial number, and nobody raised the idea of using ASCII commands to query the unit. On my side, I actually use the scopemeter for its usual purpose, as an oscilloscope, without having any in-depth knowledge of its guts. My aim was only to update the firmware and I was stuck because of a motherboard change. So, I did it my way, in a couple of hours, and succeeded. Then, I shared my experience. Now, I'm glad to learn that an easier way exists, by just sending an 'ID' query to the unit. And for sure, your trick will be really helpful to other forum members. Update #1 20240906 : corrected the dead link for the 'REMOTE CONTROL AND PROGRAMMING REFERENCE' document |

Hi asis, do you know how to change the serial number? |
| asis:
Hi feedback.loop, As far as I understand, the serial number is programmed into the D-ASIC OTP ROM area at the production stage. UHM Universal Host Mask checks it. There is a DEBUG X3510 connector, but I haven't explored it. |
