Tip & How-To about Computers & Internet

Dealing with optical cables

One of the most important tips when dealing with optical cables, is to clean the optical connectors, it has been noticed that connectors are the most common source for optical links failure, the simplest way to clean an optical connector is to use a tool called "one click cleaner", the same is called "IBC brand cleaner" for other manufacturers.

P3 DVD connector


Well........................

The numbering for power supply cables, differs from one pre-built computer manufacturer, to the next.

GENERALLY, a P3 power cable is a 4-pin Peripheral power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

(Also misnomered as a 'Molex' power cable.
Molex came out with the design for the power cable CONNECTOR.
The name stuck. Kinda' like calling an adjustable open-end wrench, a 'Crescent wrench' )

A P4 power cable is usually a 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

This power cable was brought out to provide more power for the motherboard, and specifically the Processor. (CPU)
Does NOT connect to an optical drive. (CD/DVD drive)

DOES need to be connected to motherboard though, because it is POWER for the Processor!

Moving on.............

Let's dispense with the antiquated numbering of the power cables, and show you the real information you need;

There are two types of Optical Drives out there, currently being used;
1) IDE. Also known as PATA.

2) SATA

An IDE optical drive will use a 4-pin Peripheral power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

Note the rounded corners on top.
When plugging in one of these power cables, just always remember the rounded corners go on TOP.

The data cable used is a flat IDE ribbon cable. These are general examples,

I would like you to look at the connector end, and specifically the Locating Lug on one side of the connector,

http://en.wikipedia.org/wiki/File:PATA-cable.jpg

This style of Locating Lug consists of two small 'bars'.
There are types where it is filled in. Just one solid lug.

The Locating Lug lines up with a Cutout, on the optical drive.
(Or IDE/PATA harddrive)

IF, there is no Locating Lug on your IDE/PATA flat ribbon cable, post back in a Comment.
I will show you the proper way to connect it, using the Red stripe on the side of the cable.

http://en.wikipedia.org/wiki/Parallel_ATA

If you have a SATA optical drive, it uses a SATA power cable.
This is a general example,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Between the SATA data cable connector, and the SATA power cable connector; the SATA power cable connector is the larger of the two.

SATA data cable connector has 7 contact pins.
SATA power cable connector has 15-pin.

This is an example of a SATA data cable, and it's respective connector,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Note the L-shaped opening. The SATA power cable also has this L-shaped opening.

Observe the SATA data cable connector examples, on the motherboard.
Note the L shape.

(Note: The SATA data cable connectors on YOUR motherboard, may differ in style.
The ones shown (Red) are an Open design.
There are styles that are Enclosed. Have an oval around the
L shape)

To install the cable connector, line the L-shaped opening, with the L shape on the optical drive connector.

Tip: Turn this L over to the left, then turn upside down.
The small 'foot' of the L, always points DOWN, when installing connector.


The SATA data cable connector, that plugs into the optical drive, should be a 90 degree bent elbow.
The connector end that plugs into the motherboard, should be a Straight connector.

The SATA power cable connector, and the SATA data cable connector; MAY have a Lock on top.
Usually a small depression, or Tab, or 'bulb'.
Depress with your thumb tip, to install, or remove the cable.

(Hmmm, betting now the P3 power cable may be a SATA power cable.

How'd I do? Post back in a Comment)

ADD MULTI BURNER DVD


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules


Installing additional DVD burners on your computer can turn your PC into a DVD-producing powerhouse, enabling you to burn multiple discs concurrently.


This is typically not a problem, as most computer cases can handle up to four separate optical drives at the same time.


The installation process is fairly straightforward, requiring no more than 20 to 30 minutes.


Turn off the computer and disconnect the power cord.


Remove the case screws at the back of the case and slide out the side panel.

Insert the new DVD burner into an empty optical drive bay at the top of the case.

Repeat for each new DVD drive.


Screw each drive into position.


Connect an IDE or SATA cable to the data port on the back of each drive (depending on your drive model).


Connect the white-tipped molex connector from your computer's power supply to the power port on the back of each drive.


These cables will already be inside your machine with one end connected to the motherboard and power supply, respectively.


All you will need to do is attach the other ends to the back of your optical drive.


Put the side panel back on, screw it to the case and reconnect the power cord.


Hope this helps.

my sega cartriges has horezontal lines all but spiderman maximum carnage.when I put the cartrige in the game starts but horrazontel lines come in and I cant play but the spiderman game works fine.


Sounds like the cartridge connector inside your Sega Genesis is dirty. You'll need to clean the connector AND clean all of your cartridges with rubbing alcohol. Cleaning this connector should be no big problem. Make sure your Sega Genesis is unplugged before you try any kind of cleaning or repair.

To clean your cartridges, simply use rubbing alcohol and Q-tips to scrub the connector pins clean. You will notice lots of dirt coming off onto the Q-tips. This will take many Q-tips.

This is important! Once you clean your cartridges, you still need to clean the connector inside your Genesis. Here's how:

First, get a can of compressed air. Blast air into that cartridge connector to remove any loose dust, dirt, or debris. Chances are, you'll still need to clean more.

Second, Use Q-tips to apply rubbing alcohol to one of your clean cartridges. Insert and remove this cartridge repeatedly.

Third, dry off your cartridge with clean q-tips.

Repeat steps two and three over-and-over until your cartridge slot is clean. Remember to give your Genesis time to dry before you plug it back in.

Bonus tip: If the above method doesn't get your connector totally clean, try wrapping a thin piece of cloth around an old credit card. Apply rubbing alcohol to the cloth, and scrub away at the cartridge connector.

Forgive me if this sounds condescending, but it bears repeating. Please make certain to unplug your Genesis before you attempt to clean or repair it. Safety first.
