A1200 LED to PC-Case LED?
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. http://w1.111.telia.com/~u11116395/tower/tower.html 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 me /PoliceQuest |

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? /PoliceQuest |

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. http://ourworld.compuserve.com/homep...Bowden/led.htm /PoliceQuest |
