5i25 + 7i77 Plug n Go PROBLEM!

The 7I77 analog section is powered by 5V (Either from the 5I25 or from an external source)
so failure to find analog pins is usually a 5V problem either on the 5I25 or the 7I77

So for testing if you want to use cable power you jumper the cards like this:

5I25 W2 UP
7I77 W5 LEFT

If you will use an external 5V supply for the 7I77 the jumpers need to be set like this

5I25 W2 DOWN
7I77 W5 RIGHT
External 5V to 7I77 TB1

Digital I/O requires 8-32V field power

The 7i77 has 5V logic power from the host card, I have tested. It also has 24v field Power. CR15 and CR16 are both illuminated. Here is my configuration (which was created from scratch with PNConf):

Is the 7I77 plugged into P3? (the external DB25F connector on the 5I25)

Another possibility is wrong firmware

Plug&Go kits are supposed to have the right firmware loaded in the FPGA card but sometimes mistakes are made...

Best way to check is run:

sudo mesaflash --device 5i25 --readhmid > pins.txt

and post pins.txt here

if you dont have mesaflash you can install it by:

sudo apt-get update
sudo apt-get install mesaflash


BTW 5I25 cards not working in an older PCs is very often because of dirty PCI slot contacts
you can often fix these by multiple insertions,removals of some card stock soaked in
isopropyl alcohol in the PCI slot

The 5I25 will not work on REALLY ancient (486, Pentium 100) PCs because they have no 3.3V power
routed to the PCI slots

Yes the 7i77 is plugged into P3. Attached is the pins.txt file. Thanks

Well the firmware looks correct, hmm

CR15 and CR16 are both illuminated

This should never be (red and green at once) unless the card is jumpered for setup mode

did you move the setup/operate mode jumpers?

Yes for some reason I thought that would be necessary. Well, that issue is gone, but now I'm getting the same error about "scale.spindle.gain". Sadly I don't have any time to look into it as I must go to work!
