A1200 LED to PC-Case LED?

PoliceQuest · 30 August 2008, 10:34

I will use the pc-case LED instead of the internal A1200 led, but i need the pinout value from A1200 MB.

On this link the author says that the BLACK cable from led output is Common or LED ground. I dont think so, my LED board shows other.
The GREEN cable seems to be common.

Can someone verify this and a short guide would be great!
I know that i must put some resistors on the lead aswell, like 1kohm each?

Plz

Look at this schematic....

1 BLACK = is Power LED
2 RED = Floppy LED
3 ORANGE = Harddrive LED
4 NC (OPTIONAL)
5 GREEN = GROUND or COMMON LED

I think i will go with original A1200 schematic

But, still remains which resistor to use .... 1kOHM on each LED lead?

Correction.......!

1 BLACK = Power LED
2 RED = Harddrive LED
3 ORANGE = Floppy LED
4 NC (OPTIONAL)
5 GREEN = GROUND or COMMON LED

Output voltage on pin 1,2,3 is 5v

And as for the LED and resistor:
LED = 2v 10mA
Resistor = ~300ohm (i used 220ohm)

Here you can calculate it yourself.....if you mod you case with other LED (Blue & White) use more power (amp) then red, green, yellow.
