Hey Peter.
When I enable the mpg mode does that mean I will lose my whole config or do
I just need to change something in the Hal file.
YOU just change some settings in the hal file
I'm thinking It sounds like the best thing is to setup all my io in
pnfconfig leaving the mpg inputs spare and then after that start hard
coding in Hal.
Yes leave the 2 or 4 pins (for 1 or 2 MPGs) free if you want to use a MPG
Note the enabling the MPG in the hal file will not cause you to lose the ability
to use inputs 16..19 for normal digital input use
Do you know how much I can do in pnfconfig?
I dont think pncconf supports MPG setup, so this needs to be done by editing the
HAL file
New Zealand is going in to total isolation for a month from tomorrow
because of covid 19 so I have some time for this lol :)

Andrew

Subject: [Emc-users] connecting up mpg
Hey guys.
I have a 12 volt mpg
I want to connect it to the 7i76 board. do you know if I can connect it
straight up. I think that the mesa boards only want 5 v and I am not sure
how to connect up my 12 volt mpg

I did a bunch of searches on the forum but couldn't get a definite answer.
I tried to attach a photo but it bounced back. so here is a link
regards
You can connect a 12V MPG to the 7I76 MPG inputs (field inputs 16..19), but
not
the high speed encoder input. Note that the input threshold for MPG inputs
is
2.5V so the MPG output needs to swing close to ground for reliable operation
