mm maybe some dual verification or powering scheme good luck
or someone has some similar scope to do probing ..... does the psu look like
Please can you write the psu markings ??
the motherboard is pc104 compatible ?? if it is the same ...
his is an older model. My acq board/FE board/motherboard are all different than his but the PSU is exactly the same.
my acq board is the red one and the FE board only has spring loaded board to board slots (no screws like you see in the video)
on the motherboard there is no PCI104 slot. just the regular PCIE slot and the interface board that only has one tiny eeprom on it (plus 2 ethernet connectors and one sata connector that all go to the acq board - no other component) is a small narrow board unlike the big PCI104 board you see in the video
but the PSU is the same also the front panel board is identical
EDIT: probing it is not a problem. the problem is how to run the PSU out of the box and not connected to the acq board.
I know the issue here is (at least) the missing +3.3V rail. I was hoping to probe it when it is live to see where the problem is.
Now I have to just blindly use multimeter to probe around randomly and see if I can find out what is wrong.
I think the main rail which is used for feedback and regulation is the +3.3. also it seems to be the highest current capable rail
