Hi I have a VM8090 card and I am trying to light up one led on every port 1-8, and I can’t get it work…
Here are the data…
I have connected a powersupply to the powerport (12V 300mA) and the LD11 lights up.
I have light up all of the ports and all of the LD1 to LD8 is on.
Now I am trying to connect the LED to port 1 like bellow
NO— minus ---- led -(+)-------------
1— ---(470 ohm 0,25W) resistor ----
If I connect the led+resistor direkt to the powersupply it lights up with no problem…
And it dosen’t work, what am I doing wrong ?
How should I do ?
