This might be a technical question for the G3Xpert - but maybe someone else might know.
What i am trying to achieve is a Master Warning / Master Caution annunciator similar to something you would see in a certified jet. I.e. When a RED or AMBER CAS occurs, the indicator flashes. Once you press it, it stops flashing. If another RED or AMBER occurs, then it flashes again (even if the first red message is still displayed on the screen).
So, my question is twofold:
1. On the GEA24 (EIS) there are pins 44/45 on J244 which are pulled to low then "A CAS Alert is Active". - Does anyone know exactly that this means? I.e. Is the pin only pulled low when the message is FLASHING on the screen and it reverts to floating when you have pressed the ENT key? Or does it remain low the whole time the message is on the screen?
2. Is there any way to have the CAS acknowledgment using the ENT key, be done with a remote button? I.e. When a message flashes on the screen, you can press a remote button to acknowledge it and stop it flashing (instead of the ENT key).
This is a technical question down in the weeds i know, but can't find the answer in the installation manual (rev AQ) or the pilot guide!
Anyway, what would be cool is if i could make a flashing button driven by an Arduino card which looks at pins 44/45. If one goes low, it flashes the appropriate side of the button on the panel. When you push it, it stops the flashing and at the same time brings to low a line to an unknown (maybe non-existent) pin on the G3X which acknowledges the CAS (instead of the ENT key) and stops the message flashing on the screen.
Not an important part of the build - but a fun and seemingly risk free project.
