Does the 7i92 card have to be powered and connected to the computer to make these settings?
How many Ampère does the board need?
The manual says it can supply up to 1A to each daughtercard, I have a 5V 3A power supply.
In Pncconf the pins don't match, where do I find this .pin file?
Sorry I'm really noob.

The .pin files are in the same directory as the firmware
( In the 7I92t.zip file in configs/hostmot2 )

They are created with the mesaflash --readhmid command

For example, the g540 pinout is this (7i92t_g540x2.pin) :

Thanks for the attachment, in the manual the pins on the P1 connector are different, I would have been wrong.
But in Pncconf they are not like that, I have attached some screenshots.
I haven't changed any settings on the previous pages, should I?

I've searched other forum threads and info online but can't find answers. Can you link me a guide to understand how to wire the stepper motor drivers?

Sorry I know it's long to explain to a newbie but I don't know where to find this information.
Do I have to set up the ethernet connection first following this guide?

I tried, with "ping 10.10.10.10" in the terminal says "destination host unreachable" but with "ping 10.10.10.11" works, the average ping is ~0.040ms.
But if I check the configuration with "mesaflash --addr 10.10.10.10 --device=ETHER --readhmid" don't find any ether board.
I double checked every setting listed in the guide, everything is ok.
(The card is powered with 5V and connected directly to the computer)

It is possible that 10.10.10.11 is your own PC, though that would normally be 10.10.10.1

I the card configured for the 10.10.10.10 IP address?

You could try ping 192.168.1.181 as that is the alternative Mesa card IP address.

||W5 | W6 | IP ADDRESS
|| DOWN | DOWN | FIXED 192.168.1.121
|| DOWN | UP | FIXED FROM EEPROM (default 10.10.10.10)
|| UP | DOWN | BOOTP
|| UP | UP | INVALID

So, check that the W5 and W5 jumpers are set W5 = DOWN and W6 = UP.

I setted the 10.10.10.11 address in the IPv4 settings.
With ping 192.168.1.181 says "destination host unreachable".

If you set 10.10.10.11 in the IPV4 settings then your ping to 10.10.10.11 is finding the PC on loopback, not the 7i92.

Did you check the jumper settings on the 7i92 board?
