Opencockpits display cards doubt

Dear friends

actually i have all my overhead finished but i´m not able to make the displays of pressurization and electric working

i have 2 displays cards.
Is it necesary to add ome lines to sioc.ini?
how can i test it?
when i use controlador.exe adn i select all on, all the digits pop up, but i would like to knop how can i pop on one by one.

in the other side, i would like to know how to interface with prosim.
Prosim has not implemented yet the presurization but yes the electric panel but i don´t know how to program it

For the presurizations, does anyone know how to make a counter for landing altitude??

any idea?
