If you have plucked these cables from the 'usb port'(the one you insert on your computer) then you are suppose to connect them in the following patterns
(if you are connecting it to a laptop, and the USB port is on your 'right' hand side then these are the followings)
TOP to BOTTOM
BLUE (top)
GREEN
WHITE
RED (bottom)
and vice versa for the other hand side
I had to create patch cables in my Infotech class and had to memorize at least straight cables. starting from pin 1 (left to right) Straight-Through: White-Green, Green, White-Orange, Blue, White-Blue, Orange, White-Brown, Brown White-Green is pin 1 and Brown is pin 8 Cross-Over Cable: White-Orange, Orange, White-Green, Blue, White-Blue, Green, White-Brown, Brown
There are four wire pairs in CAT 5 cable. (Orange&White Orange, Blue&White Blue, Green&White Green, Brown&White Brown) Not in order of use
A composite cable is one that has three video (Red, Green, Blue) cables and 2 audio (Red, White) cables.
The yellow cable can be used for the green wire, but cheap white/red/yellow (composite video + audio) cables will have issues working as component video cables for longer lengths, as they usually have poor shielding.
You can tell the difference in multiple cat5 cables by simply looking at the wiring color. The colors include white/green, green, white/orange, blue, white/blue, orange, white/brown, and brown. Each color has a different combination of pins, pairs, and wires, each for different applications.
audio
The black and white cables, or possibly black and red, are analog audio. Green is one of the three component video wires, bundled together as red green and blue. Without knowing what components you have we have no idea where you should connect these, or if it is even possible with the gear you have.
some green are white.
Depends on what you mean by audio, if you mean audio as in the 3 cables that connect into your tv (i.e red, yellow and white) then attach the red and the white (as they both control stereo sound) If you are on about hd cables then attach the blue and green cables into the appropriate sockets in the back of the plasma screen. If you are on about audio hi-fi or audio system then use the twin cable and plug both ends into their appropriate sockets Jackson, =D
(orange white) (orange) (green white) (blue) (blue white) (green) (brown white) (brown) (green white) (green) (orange white) (blue) (blue white) (orange) (brown white) (brown) In a crossover cable only the green and orange pairs switch positions.
For common home network, a full duplex cable would have White Orange Orange White Green Blue White Blue Green White Brown Brown From left to right with the clip on the bottom and looking from the end where the cable inserts.
Monster Cables use Blue instead of White for the 2nd audio plug in RCA cables.
