Here is 5I25/6I25 firmware for a 7I76U with the PKTUART

I can try to help more later, but note there is another user trying to get a Omron MX2
working with a Mesa card and having issues. I suspect I may have to acquire a MX2
to try and get this going.

The 7I76U manual has the RS-485 wiring information (and you must use RS-485 mode with the 7I76U
so you lose on estep/dir output)

Hello,
Hope you are well,
I have bought a 7i76EU and would like to know if you have any specific firmware I should use.
My setup is Linuxcnc 2.9.7, VFD is Omron MX2 and I will connect this using the RS-485 mode. Other config details, I am using 5 Gecko Stepper Drives driving X1,X2 Y, Z and A rotary axis. I don't have any encoders.
All Jumpers are default and I have a unregulated power supply that I can connect to the board.
Can you also confirm if a CAT5 cable or higher speed cable is required.

Thank you.
Kind Regards,
Orrin
