Wake up/keep alive wire

Recommended Posts

Incepator in electronica ( be merciful). 

Ar putea cineva sa imi explice cum functioneaza wake up signal / keep alive signal? Unitatea media de pe masina personala (care are modulul de afisare separat), are doua fire (  1-comanda pornit/oprit si 2-semnal veghe) care duc la modulul de multiplexare. Now, firul de semnal veghe pleaca si in celelalte module (afisaj video, multimedia box, joystick etc). Nu inteleg daca radioul transmite semnal catre modulul de multiplexare, iar acesta transmite semnal veghe la celelate module, sau tot radioul transmite semnal veghe)

As vrea sa inteleg cum transmite semnalul, cum as putea sa il simulez, pentru a elimina afisajul video, si sa pot porni radioul (daca afisajul video nu e conectat, nu porneste). 

Stiu ca este prezenta si reteaua CAN, m-am conectat si primesc frame-urile aferente, imi ramane doar sa gasesc pattern-ul corespunzator, si daca modulel au un fel de feedback in care sa transmita daca sunt sau  nu conectate/alimentate.
