Hummmm I don´t know if I would be able to handle this, yes I have operating configuration, I had rather, now it doesn´t run :)

How can I map or know the chinese BB pins and the BB itselfs denomination?

It smells as a new challenge and learning for me.

The firmware did not change any 7I76 connections
so your original hal/ini files should work

The PWM output is on DB25 pin 8 (mesaflash should show this)

Well now I am unable to run the configuration that was operational, I launch the application and I get the error screen with a bunch of lines that pin do not exist.

If the firmware doesn't change anything (I thought so too) what could be the cause?

Until Thursday I will not be in the place of the machine, which I remember right now it gave me an error on line 39 of the .hal (the first one that appears in the configuration) that corresponds to a limit switch, in the previous warnings more lines.

As soon as I get back I'll check what you say and copy the report first before doing anything else.

How can it be possible if I haven't touched anything?
I have simply flashed the new firmware. I'll check it out as soon as possible though. Thank you Tommy.

Does the orange connector on the 7i76 have 8V to 28V power going to it?
How is the field power jumper set up?

I have not touched anything Tommy and it was operational and after writing the new firmware I get the report messages.

However, as soon as I have a moment I will look at it and check what you tell me.
