Remote Control Molex Connector Kit Troubles

Ooska · 07-25-2007, 09:58 AM

Ok, so I bought this Remote Control Molex Connector off e-bay, in hopes that I could make some lights in my PC turn on and off. But I have no idea how to work it! It has 2 handsets, and a reciever. The reciever has a red wire(12VIn) a white wire(12VOut)and 2 black wires(ground). I can solder wires into place if I need to. What do I do?

Can you post some pictures of the device and its connectors?

Surely.

Are you sure it has two +12v lines and not a +12v and a +5v line? That is what a standard molex connector has. I think you need to hook it up to a molex connector at the end. What does the manual say for instructions?

The pictures show it as having tinned leads. So it's probably +12 in, ground in, ground out, +12 out, as stated. It appears as more of a DYI device then anything else so the instructions will probably not be specific to any perticular use. That said, it can be used in a computer, but i highly doubt your computer parts bin is anywhere near as deep as mine. What i've done is taken some old sigma front panel fans, hacked the molex off some of them with about 3" of lead, and i'll use them to connect whatever i need to connect, and use extension wires to make the distance difference. That's what is powering my CPU fan right now since my mobo doesnt use the usual CPU fan connector.

(Note that i have a junkload of sigma computers so that's where i often source my stuff from.

I don't know what you mean by "+12v in and +12v out". DC voltages from a computer power supply are either positive (most voltages are), negative,, or ground, which is neutral. In a molex connector, There is a +12v to ground connection, and a +5v to ground connection.

If you want to control a fan with it, you take a +12v and ground wire, strip it, and stick the metal tip into the 3-pin fan connector. The negative (black) goes to the ground, and the positive (usually red, which actually doesn't make sense, but it is anyway) goes to the +12v.

look at the picture. It has a +12 in and a ground in, then a +12 out and a ground out, which is switched on and of by the box (reciever) and wireless transmitter. You have to ignore the word molex.

Hi Guys .. what I see is a black box that responds to an infra-red signal (remote control) ..
the 12V IN is the power that goes into the box ..
the 12VOut is the 12 Volts that comes out of the box ..

the idea is that either a transistor or a relay are inside the box and when the remote is operated it will either connect or disconnect teh 12Vin to the 12V out allowing any device that operates PURELY on 12V to function ..

let me know if that requires clarification

**kodi** · 07-28-2007, 12:16 PM

Done_Fishing has got it right,connect the two 12v IN leads to a power source (a molex will do) and the two 12v OUT leads to the lights

**Done_Fishin** · 07-28-2007, 12:34 PM

to correct kodi's typo .. you connect the 12VIn to a yellow wire from your power supply .. along with one black wire from the black box to another black wire from the psu .. you can use a spare molex if you want by using from an floppy adapter or power splitter .. make sure that you solder the right wires in the right places .. you won't require the red & black pair they are 5Volts and if you use those you might end up doing damage ..

now connect the 12Vout to your 12Volt light system along with the black for ground ..
It's important you connect properly .. any errors can be dangerous .. for you , youir mobo, your lights and your power supply ..
if you have any doubts at all .. ASK!!! and wait for an answer .. PATIENCE is the key word here

**Done_Fishin** · 07-28-2007, 01:26 PM

In response to a PM .. I am pasting a copy of my reply here ... just in case someone else requires more information ..

Quote:

The power supply is the (normally) silver coloured metal box that sits at the back of your computer above your motherboard ..

it is connected to a power cable that goes to your wall socket and supplies the mains input voltage
inside your PC it has a lot of wires leaving it which go all around your PC supplying low voltages at high currents

there is one large cable that connects to a 20 or 24 pin connector on your motherboard

along with another 4 pin square cable that connects close to your CPU (Central processing Unit)

Your Hard Disk Drive(s) and your CD/DVD ROM drive(s) are connected also from the power supply using "Molex Connectors" which have 4 wires inside them 1 Yellow, then 2 Black followed by a RED wire.

The Yellow wire is 12 Volts (12V), the RED wire is 5 Volts (5V) and the black wires are Ground or Zero Volts (0V)
In the picture the wires are doubled on the MOLEX connector because it's an intermediate connector .. there can be one two or 3 connectors on length of cable. If you wanted to connect your 12VIn to one of these connectors you would need to use an adapter similar to this and remove the unwanted connector(s) and wires.

And then use the instructions I posted here to connect the remote to the adapter 12v out:

**magnethead** · 07-28-2007, 08:15 PM

wait, YELLOW is the 12 volt line? I thought red was 12 volts and yellow was +5 volts, and orange was +3.3 volts?

(less fans, where red is +12, black is ground, and yellow is the PWM/RPM signal wire)

**TheMatt** · 07-28-2007, 10:35 PM

Nope, yellow is +12v, red is +5v, and orange is +3.3v. Black is ground.

For some reason though, a lot of 12v fans that use the three pin connector have the yellow wire as the signal wire and the red wire as the +12v wire. The black is still ground. I don't know why they do that...
