Yes Jeff, that looks like exactly what I did. -- Bearing in mind that it
was for a Acess PCI-DIO-48s board. I think that it
can be used with the Axiom board as well with 100% success ( I wish I had
one of their boards to test ) .
I think someone should test this before any changes are made for
EMC2.2.0. ( see if the Axiom board sets all outputs low upon initialisation
) ( loadrt hal_ax5214h cfg="????????" from halrun)
Thanks, Dave
