Mesa 7i97 setup problem

Not sure what you mean, for example page 8 of the 7I97 manual has the pinout
of TB1 for encoders 0..2.

Yes and TP5 Pin2 is IN8 and now - ? Where is described what pin has what name for hal config? If i want to use this Input Pin with a switch - what i have to do in hal?

So i'm not mean you explain me that - i mean where is the manual for explain the working with these mappings of pins and names?

linuxcnc.org/docs/html/hal/basic-hal.html

These not all or?

The hal file example shows inputs 0,1,2 connected as X,Y,Z home pins

Input 8 would be identical except for the number
