| Can I send 5V power through a serial cable pins ..... (not wires) |
| << < (5/5) |

(1): The black wire will carry the same amount of current as the red one, so if you use 4 pins for the red wire, you need to use at least 4 pins for the black. I showed 5 in my drawing just to make it simple. You could leave one pin put of the nine connected to nothing. (2): The negative is the same as the ground in this situation. Black= negative on the led and it also = ground on the power supply. (3) Yes, you can attach 4 separate leds to four pins on the male side, but these 4 pins need to match the 4 pins with red wires on the female plug. The negatives (or grounds, or black wires) on the leds can attach to separate pins on the male plug, but these pins need to match the pins with black wires that are on the female plug. Dont forget that somewhere these leds need resistors. Each led needs its own resistor. The resistors can go between the led and the positive pin, or between the led and the negative pin. I think Im lost here, are these leds wiring back to the ledwiz? or are they going through the db9 connector to the power supply? Do you have a drawing you can post? I dont want to lead you astray here.. Dont worry about the drawing being crude, I just need to know what exactly you plan to do.. |

I attached a picture of how I would like to attach my LEDs. I am going to have 4 sets of 4 LED lights connected together in parallel. Each set of 4 LED lights will be connected to one port on the LEDWiz. I might end up having 5 sets of 4 LES lights instead ... but the picture only shows 4 sets. Anyway, I am going to use a molex connector to connect to 5V and GND connections to the LEDWiz. I am also going to connect a "female" serial cable pin adapter to the power supply side (splitting the 5V power wire up as you recommended). The associated "male" serial cable pin adapter will be used as a quick disconnect between all my LED lights and the LEDWiz. Notice the LED lights each get 5V power and the other wire of the LED light goes directly to the LEDWiz. Anyway, please let me know if I can do this without burning down anything. PS: Each LED light has a resistor on it. I already soldered all resistors on them properly since I already confirmed some of them lit up. |

I dont see any problem with fire at all. Just wire the db9 connectors like you have it drawn. (Dont tie all the grounds together like I showed in my picture.) Looks like you have a plan... cant wait to see some real pics of your project... |

I will put up a bunch of pictures once I am done. I got an electrical sander for Xmas so now I can start my wood putty'ing and sanding. After that comes painting, etc .... and then wiring everything up. Unfortunately I believe this might take me another month ...... finding time is hard lately. Anyway, thanks for the information ...... and verification ..... and patience. Happy holidays! |

Merry Christmas.... Good luck, and cant wait to see your progress! |
