Motherboard Manual - KOB 693 DCS

[Shubhrajyoti]

From where can I find the manual for KOB 693 DCS motherboard. I need
to plug the USB cable but could not locate where to plug it as "USB"
is no where printed on the motherboard. My device manager shows the
following under Universal Serial Bus controllers:
# USB Root Hub
# VIA Rev 5 or later USB Universal Host Controller

This thread:

http://www.duxcw.com/yabbse/index.php?board=3;action=display;threadid=16443

mentions this link as a possible source of info. The
mercury-pc.com site is currently not working, as I cannot
even ping it. Maybe if you try this later today, you might
find another link on this site with some info. The mercury-pc.com
web site is owned by KOBIAN SINGAPORE PTE LTD, according to
Apnic.

USB interfaces come in two forms. There could be a USB connector
in the I/O area on the back of the computer. Or, there can be a
2x5 header on the motherboard itself (a 2x5 header with one pin
missing, for a total of 9 pins). With the motherboard header,
you usually need an adapter to gain access to the USB.

(Example of one form of adapter. There are also adapters which fit
in place of a PCI slot cover.)

The easiest solution, is to go to your local computer store,
and buy a PCI USB2 card. Some of those can be purchased for $10
and use a spare PCI slot on the motherboard.

Another ingredient, is the OS you are using. If you have WinXP, then
USB2 is supported with the appropriate service pack. If you are using
an older OS, like Win98, then what you want, when you buy the PCI USB2
card, is a driver CD. Cards that come with a driver CD might be a bit
more expensive, but the advantage would be, they may have a Win98 driver
on the CD that comes with the product (an OrangeMicro driver). You cannot
rely on a later download from the manufacturer's web site, and getting
the CD with the driver reduces the risk of being stuck without a Win98
driver.

HTH,

OK, after a bit more searching, try this link:

http://www.mercury-pc.com/download/uploaded/drivers/KOB_693_DCS(1.5).pdf

And the answer is not what you would expect. Kobian has a proprietary
connector (J7), where you would plug in a USB adapter. They do not
include the pinout in the manual! So the PCI USB2 card looks to be
the most practical solution. Unless you are skilled at tracing
copper tracks and guessing at the wiring.

My web searches suggest that you may have a rebadged ECS or PCChips
board.

See http://members.cox.net/jhawk56/sig.htm which refers to ...

"all PCCHIPS and equivalent motherboards sold under names ECS,
Elitegroup, Amptron, Matsonic, Eurone, Kobian, Mercury, Syntax,
EagleTEC, and Elpina"

FWIW, the pinout for an 18-pin "ATX Form Card" is probably this one:
http://www.amptron.com/html/atxformcard.pinout.html

If I've got it right, then the pin numbering of your ATX Form Card
connector J7 (as denoted in the above Amptron table) would be as
follows:

USB1
1___7_____17
|____x___|
2 8 | 18
USB2 |
|
key (pin 10)

The above pinout matches the functional layout of connector J7 on my
PCChips M571 board, but my pins are numbered from 1 to 9 along the top
side and 10 to 18 along the bottom.

The "ATX Form Card" you found, is apparently still for sale.
There is one here for example:

http://www.pccables.com/70599.htm

The pinout at the USB end of the 2x9 header, is not exactly
compatible with currently available USB adapters. For example,
if we take one of these:

http://www.frontx.com/cpx101_2.html

It has:

X Red: +5V
X White: D-
X Green: D+
X Black: GND
X Black: Shield GND <---- remove to avoid a short...

The shield GND wire would have to be removed from the 1x5 connector,
in order to prevent a short to the +5V pin.

Adapters which have a 1x4 connector would be OK.

For example, this dual USB adapter, which uses a 2x4 connector,
could be connected directly to one end of J7.

I've never heard of an "ATX Form Card" before. That is today's
"learn something new" I guess.

The devious marketing people at PCChips like to redefine terminology
in an effort to deceive the buyer. For example, my M571 motherboard
has an SiS 5597/5598 chipset which they call TX-Pro-II. The onboard
graphics is referred to as an Advanced Graphics Port - there is no AGP
(Accelerated Graphics Port) slot, only PCI and ISA. The onboard sound
chip is actually a CMI8330A but is labelled as Sound Pro HT1869V+.
