The amplifier is full of inconsistencies. Such as different Encoder Channel Polarity between Linears encoder inputs on the same amplifier. Wrong pin out on some limits switches inputs. It must still remain some bugs...!?!
Just to make things clearer. The MC-4SA isn't a National Instruments product but produced by National Aperture Inc. National Instruments is also a vendor of motion amplifiers but they are called MID 76xx.
