My MESA 7i95T wiring

 it means , that 1 click to MPG = 4 pulses for feed?

so what is the solution ? set 1/4 of the feed value ?

only use the input designated for MPG (foto - input A0,B0) ?

 



i am trying to understand the links

MPG wheel connection - fixed

MPG ENCODER INPUTS

Standard 7I95T firmware provides 4 quadrature MPG encoder inputs on isolated inputs 0 through 7.
Since the input threshold on isolated inputs is about 3V, its best to use sinking inputs (with the input common terminal tied to +5V) with TTL output level MPGs.

INPUT ENCODER 
0     QUADA-0      MPG 0
1     QUADB-0 
 
2     QUADA-1      MPG 1
3     QUADB-1 
 
4     QUADA-2      MPG 2
5     QUADB-2

6     QUADA-3      MPG 3
7     QUADB-3

 


The problem for me is that the MPG hand wheel function for inputs IN 00-07 cannot be selected from the submenu in the PNCONFG menu.
I don't know how to manually edit HAL.
