Hello,

This is a first time I am trying to connect motherboard (V4MDMP) with
a computer case. I don't understand some names from the manual, for
example
vcc5 (positive 5V?), nc (not connected?), gnd (ground?). Some
connectors are multicolored - is there any standard with colors? Each
pair of wires have a white color? Does white is a ground?

Are there any Interne sites that describe any standards or how to
connect motherboards?


Thanks,

Zalek
 
Hi,

It sounds like you're talking about the USB connectors.

The colors are like this:

Vcc == +5V (red)
USB- == - data (white)
USB+ == + data (green)
Gnd2 == Ground 2 (black)
Gnd == Ground (black)
Nc == No connection

Somtimes Gnd2 is called USBOC (usb over-current) instead.. I have no idea
what purpose this serves..
Also, one USB connector may have gnd and gnd2, while the other has gnd and
nc..

Your motherboard manual should tell you which pin correponds to which
connection above.

Regards,
Chris

Thanks Chris,
My motherboard used only this short names - after seaching the
internet I found that ground is usually a black or white cable. Using
this hint I successfully assembled my new PC (MB - Mach Speed V4MDMP
with Athlaton +3000) and this message is from the new machine.
