  • CNX-P2140 Questions

    Alright, I am getting ready to start my third CarPC project and this is by far the most technical I have got with an install. I am using a CNX-P2140 with a Dell SX270. My first question is, what is the benefit of running my touch screen off the secondary +12v power on the 2140 instead of hooking it right into my acc. wire that used to go to my radio? I have a lot of other questions but I will bring them up as I go. Thanks a lot in advance.

    Some screens require regulated 12v power. Connecting such a screen directly to the switched power line could damage the screen, rendering it inoperable.

    It all depends on the capabilities of the screen you're running.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Under normal circumstances, a signature would go here.

      Alright, that makes sense. I have a Tview 7" for the screen. I doubt it needs to be regulated. I had the same monitor in my last setup hooked straight into the acc. for over a year with no problems.
