Chinese Mesa 7I92 from aliexpress NEW was created by Sekai
Hi.I bought a mesa card from aliexpress to power my lathe.The board works with 10.10.10.10 it pings and output that gives me with command:sudo mesaflash --device 7i92 --addr 10.10.10.10 --readhmid
The problem is i dont know how configure linuxcnc. I have the doc from the seller uploadnow.io/f/9v0gkpb
This is my first time with mesa card.

You did not buy a Mesa card. You bought a Chinese clone hoping to save some money then expecting help.
The best thing you can do is read the Linuxcnc documentation.
But any of the quirks with the card itself you are going to have get support from the vendor.
Without knowledge of the schematics no one can say whether it will operate electrically as original Mesa 7i92.
What you have done is bought a rip-off and now expecting those that are loyal to Mesa Electronics to dig you out of hole.
And to be perfectly honest there are plenty of threads regarding configuration, plenty of resources on YouTube and plenty of advice in the docs.
