Field power is required for the serial communications to work .
So that should solve your problem

Not yet, I have it all laid out on a table, just testing to get the
initial config right to get the boards working. So field power is
needed? Ok, thanks, I will try that!

you should have power 5v between pins 4&5 and 7&8 of the rs485
pins 4&5 are gnd 7&8 are power , check your gnd in particular
if your drawing too much current you may not have 5v at this point
i tend to use external power directly to avoid any cable problems etc

I got so far that manipulating pwmgen value pin does change voltage on
7i48 outputs, so that seems to be correct and working.

I think it would be something like 5i24_16_svss_6_8_7i48.bit
The closest I can find doesn't seem to be built for the 5i24_16. There
is a file PIN_SVSS12_6_7I48_7I52_72.vhd but that onl
Hello!
I need a little help with starting point for a LinuxCNC config.
There is 5i24 board with 7i48 attached to P2 and 7i44 attached to P4.
7i44 board has 7i71, 7i71 and 7i70 boards attached.
5i24 board is flashed with 5i24_16_svss8_8.bit firmware.
I have 2 questions:
1) which is correct firmwa
