This all I see in the manual for setting up the MPG (not much to go on)......
Manual Pulse Generation (MPG)
MPG Source Type
This section defines MPG (Manual Pulse Generation) Quadrature encoder source. Both Differential and
Single Ended Encoder types are supported. One differential encoder can be hooked up to J11 while
single-ended encoders can be wired to J6, J8 (encoder usage), or J10. These encoders are defined as
Hard Encoder. An Undefined Encoder option causes HiCON to ignore MPG Source values.
MPG Source Index
If Hard Encoder is selected in MPG Source Type, MPG Index denotes the hardware encoder channel.
