    P1900 Hookup Help

    Ok. Just need a checkoff from you guys. Please let me know if I have reasoned this out correctly. I want to run the mac mini in sleep mode and attempting to run my lilliput off the P1900 too. I want my lilliput to turn off when the car is not running and on when the car comes back to life.

    I have set the P1900 to the following settings:

    1-2 Open
    3-4 Open
    5-6 Jumpered
    7-8 Not Used (open)
    9-10 Open (Dylon Follows Ignition)

    Jumped to +12v (to power screen)

    Follows JP4 setting

    Follows Dylon

    +12v Setting

    +19v??? I am questioning this one. The mini runs off 18.5 right? And the instructions say the actual power is .5 volts higher to compensate for wiring losses. So is +18v correct or +19v?

    Also on the Input Power (J1) connecter, Do I need to utilize the Blue wire? Pin 2?

    1 more thing. What size fuse do you recommend running inbetween the battery power and P1900? If any?

    Thanks alot for all the help people. I think I have it figured out, but want to make sure.

    I chose to supply with 18 volts also I used a 15a fuse between the battery and the P1900. I bought an amplifer wiring kit to power the P1900. I believe the blue wire is for remote start (like from a key fob or else where). I have finals today and woke up too early to check your pin settings. Sorry. Like the diagram shows:

    Sorry for the confusion guys. Here's my reply from our CarNetix forum.
    You're right on the money! Everything is correct. Just a couple of comments.

    JP5 - make sure to move BOTH jumpers to the +12V position
    JP6 - Use the +18V output. As you mentioned it will actually be +18.5V.

    J1 Blue Wire - this is the Pulse Start input. It is not needed unless you want to start the P1900 from some sort of wireless remote device. You can leave it disconnected.

    Fuse - we recommend a 15A fuse somewhere near your battery.

    I aplogize for the complicated jumpering. I meant to write a "summary" in the Mac Application section of the Installation Manual but forgot. Looks like you've got it figured out tho.

    Let me know if you have any other questions.

    Thanks for all the help. This thing is pretty easy to install minus my few questions. The Y Cable is also a snap!.. So convenient.
