The MU cable only passes a very limited set of information between the units. No air information is passed through this cable. It does convey positon of reverser, throttle position, dynamic brake setup, the position of the generator field switch, fuel pump, etc.. In this fashion all locomotives can work with this information. An SD40 could be producing 2500 H.P. while an A.C. is pumping 4400 H.P. Both units are in #8 throttle forward power. Hope this helps.
