How to tell which card is which?

Hi, I am looking at det back of my Moi Pro AMD which has four cards in it.
The cards themselves are labeled 0,1,2,3 for their inputs, but I dont know how to tell which card it is.
Can you please give me advice on numbering on the cards for the DMESG FRONTEND output?
Thanks
