Mesa 6i25 - Mesa 7i76U - Omron MX2 wiring

Hello,Im using LinuxCNC 2.9Can I please get some assistance with wiring of the mesa 7i76U to an omron mx2 VFD and the HAL and INI file and the correct firmware recommendation.  files.omron.eu/downloads/latest/manual/e...rs_manual_en.pdf?v=1        

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)

Ok thank you I'm happy to use the RS-485 mode,

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

Hi, PCW
Is there available firmware, for the configuration: 7i92 + 7i76U_pktv3d.bin  ?
I need to use the modbus characteristics of 7i76U 
Thanks, in advance.

No, but I can make one tomorrow.

7I92 or 7I92T?

Sorry that was the wrong firmware for a 5I25/6I25  --> 7I76U using RS-485 mode
The correct firmware is this:


 


 

Hi PCW
Thanks a lot of. 

I was waiting for your reply, but I hadn't seen it. I tried today, but got this result:
I used MesaFlash version 3.5.16.
Before flashing the firmware 7i92t_7i76u_pktv3.bin, do I need to update the board with PIN_7I76U_PKTV3_34.vhd?
