    Open Cockpits USB outputs card.

    Im considering using the OC USB outputs card for annunciators and was wanting some feedback on the wiring for these. As I understand it the positive is common and how is everyone distributing the power to the LED's via the common positive. I also see three sets of power connectors. Which is used to power LED's and which is used for the external power??

    You can download the manuals for the USB Output cards from the OC website. They are in several languages with good explanations and some simple diagrams.

    Re: Open Cockpits USB outputs card.

    I have read the manual and I dont find it to be too well thought out. I understand which connector is to feed the LED's but it dosent make it too clear on which connector is for an external power supply. Also im trying to think of a way to distribute the common + to 64 leds without the use of a mess of pigtails and wiring.
