    at first ... then i learn about it !! hehe

    all i can say thank god for this forum ............

    here's the problem i have just brought your usb output card from opencockpits. when i run the test software " test usb output.exe"


    firstly the five boxes at the top of the software rotate non stop with numbers? is that right?

    secondly i have connected some leds from my fmc to the ground on the usb card and the postive to 59 - 63 . but they dont work when i click "all on " with the software. but when i connect the postive to the postive terminal next to the ground terminal on the usb card the led lights!. is that also right ?

    my kit so far.!!!
    gf mcp - working
    op efis - working
    gf 737 rudder - working
    fmc - keys working ... no screen or leds yet...

    Yes. The USB outputs card works with a common + and all the outputs are separate grounds. That is quite opposite from the Master Card which works with a common GND and separate +5 V outputs.

    Note that the common + for the USB output card can be set to 5V but also to higher voltages; for leds I recommend to use 5V

    ok nico that kind on makes sense i think i have got the wiring wrong on the fmc.
    . i have all of the gnd connected together but with the resistor on the negative side of the led.

    can you tell me the correct way to wire an led and resistor.

    many thanks

    Hi,
    USB card settings:
    connect +5V and gnd to the POWER connector (NOT the external option)

    JMP1: OPEN
    JMP2: CLOSED

    Connect POWER terminal (second one from the bottom right) to a resistor;
    connect resistor to + side of led;
    connect - side of led to one of the outputs, say # 63 (next to the POWER Terminal

    regards,
    Nico

    No.

    It also does not matter whether you put the resistor in the + lead of the resistor (between power and resistor) or in the - lead (between GND and resistor), as long as you put a resistor in series.

    Hi Nico,
    There are a few too many resistors in there!
    I think you meant to say:
