Very good point. However, it's not just that it has a specific protocol. One could (and should) conjecture that this armor is primarily strength-based and wouldn't spare so much tech to electronic shielding and such--items vital when going against a tech-based foe, such as Ultron. Simply stated, Ultron could (presumably) easily take out such a suit without lifting a finger through any number of electronic countermeasures.

It would have been nice for them to address something like that in the movie (like in Iron Man 2, when War Machine suggested, "...you should lead with that, next time..." and Tony told him it was only a one-shot). But, us true-believers are still at the mercy of Hollywood. They leave us to fill in those blanks. :)
