Need help loading pmc parameters using the hex looking backup.

Got the cnc side loaded from previous saved file.

Can't get the PC parameters to load.

Were saved recently by fanuc.

Since I tried:

I/O, input, fdcas, exec.

Says executing, then sendfrom laptop and says file error.

Tried chanel.1,and 2 .
Cd4a and cd4b.

Tried different baud rates etc.

We don't have original paper copy of orignally parameters.

Thanks, any help would be greatly appreciated.
