I had a lightning strike damage my original FX727B board which handles rs232 comm to my Griffo bros DNC connection.
I replaced the board with another FX727B board purchased from ebay.
I installed a new battery, it was missing, and started up the machine.
The display showed a C axis which we don't have but I proceeded to start setting parameters.

On start up got nasty error for invalid M1 - M16 codes no big since the "new" board needed parameters
Entered all parameters from my backup paper list from previous FX727 board, even the evil OP1 - 16 which required a character for the number of bits set.
Then hit page and found the "D" parameters D1 - D64

I did not see them when i backed up my parameters on the old card the page did not show up.
Are these the hidden parameters and how can I see them on my old card?
What are they and how do i get correct values for them?

Then hit page and found the "D" parameters D1 - D64

After loading hard copied parameters by hand the D parameter page went away.

From MEUA learned how to access additional pages by pressing F3 key and inputing 1131.

The hidden pages were all ATC parameters which I blanked and the controls then worked correctly

MEUA also went through the parameter list I had and confirmed we had all known parameters in.

Thanks to MEUA
