Hello!
Who can help ?

When accept components changes receive the following error:

PNCconf encountered an error. The following information may be useful in troubleshooting:

Thats a limitation of pncconf. It can only configure boards with up to 5 sserial channels.
Looks like the board is asking for at least 6.

It doesn't matter how many you use, it matters how many the board has available.
Bottom line is that pnccond needs to be modified to configure that firmware.

Is this mean if I decrease number of sserial by flashing 5i25 for example with one 7i77 and four ssi plus two sserial this should work ?
This kind of configuration is was created by PCW somewhere on forum.

Just flash the 5i25 with 7i77 and 7i74 firmware
Thats all you need. Plug the I/O cards in the 7i74 apply the proper power to them and linuxcnc will give you your pins.

/edit Dont worry about pncconf with the extra boards. There's no line to add in hal, the pins will be there. You just have to use them.
You will have to add the second serial port to the loadrt hm2_pci line though.

A retrofit i did several years ago using SSI serial absolute encoders, mesa 5i25, 7i77, 7i74, 7i70 and 7i71, with attached working test config.

Thank you, Bob.
That was the first big retrofit and it had all the complicated stuff coupled with a dead computer and controller, so it took a while to figure out over 600 wires ! Luckily almost half of them were GND. Finished it in 2 weeks, working evenings and nights as it was in an industrial estate.
Andy, PCW and Todd helped a lot, so thank you all.
The thing weighs over 5 tons !
