MF Digital Scribe 9000 with Picojet disc printer. Hello, could anyone please help with the pin configuration connections of the 9 pin seriel cable to mini din control cable connection from the duplicator...


Have you tried emailing tech support?

http://www.mfdigital.com/techsupport.html

Failing that, and lack of pinout, serial communications can be done with only 4 connections, Transmit and Receive (TX, RX) ground (GND) if you do it with no handshaking. You'll need Data Terminal Ready (DTR) and Data Set Ready (DSR) and or CTS/RTS (Clear/Ready to end). You may have to trial and error it.

Pin 1 - Carrier Detect (CD) - only needed for a modem
Pin 2 - Receive Data (RX) - Cross over with TX
Pin 3 - Transmit Data (TX) - Cross over with RX
Pin 4 - Data Terminal Ready - Cross over with DSR
Pin 5 - Signal Ground (GND) - Goes to other side ground.
Pin 6 - Data Set Ready (DSR) - Cross over with DTR
Pin 7 - Request To Send (RTS) - Cross over with CTS
Pin 8 - Clear To Send (CTS) - Cross over with RTS
Pin 9 - Ring Indicator - Only needed for modem

Need circuit diagram for HP m8100 GC673AA


HP Support > Pavilion Media Center M8100n Desktop PC > Main Support page,

http://h10025.www1.hp.com/ewfrf/wc/product?product=3440614&lc=en&cc=us&dlc=en&lang=en&cc=us

Product information > Product specifications > Motherboard Specifications, MCP61PM-HM (Nettle2 {HP name} ),

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01077676&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3440614

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires connect to, is the Front Panel header.
(Power On switch, Power On LED, HarDDrive activity LED, etc)

The Front Panel header is Black, rectangular in shape, and is situated in a vertical position; located in the Bottom Right corner of the motherboard. (Next to the mounting hole)

It is a standard 9-pin HP Front Panel header,

http://h30434.www3.hp.com/t5/Desktop-Hardware/Getting-a-new-case-i-need-Front-Panel-pinout/td-p/842897

Scroll down to the 9-pin Front Panel header photo, and pinout.

The 4-pin side is the EVEN side. Pins 2, 4, 6, and 8. There is NO Pin 10.
The 5-pin side is the ODD side. Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light Emitting Diode, so it is redundant to call it a light)

Pin 1 is for the Positive ( + ) wire.
IF the HDD LED is dim when the harddrive is active, (IN use), switch the wires around.

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

C) Pin 9 is N/C. Not Connected. Reserved for factory use, and it is +5 Volts.

D) Pins 2 and 4 are for the Power On LED.
Pin 2 is for the Positive ( + ) wire.
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

Scroll the HP Support Motherboard Specification page down. Click on the + sign next to Motherboard Layout.

Left to Right on bottom edge of motherboard, Internal Connectors;

AUDIO_1 is for the audio ports on the Front Panel.
ATX_IN is where the small audio cable from the optical drive plugs in.
(CD/DVD drive)
IF TWO optical drives are used; the Main, or Primary optical drive, is connected with the small audio cable. NOT the secondary optical drive.

HD_AUDIO also connects to audio ports in the Front Panel.
May be mistaken, but don't believe SPDIF_OUT header is used.
1394A1 header is for the Firewire ports in the Front Panel (1394a)
USB 2 and USB 4 headers are for the Front Panel USB ports.
USB 1 and USB 3 should be for a Card Reader.

Need where the power cables go, and what they look like? Just post back in a Comment.

(Be SURE to FOLLOW Anti-Static Precautions)

How do i hook up usb button in intel 845 motherboard


Well, that's a start. You know you have an Intel motherboard in your eMachines, that uses an Intel 845 motherboard chipset.

It is an Intel D845GVSR motherboard.

http://www.intel.com/support/motherboards/desktop/d845gvsr/sb/cs-008823.htm

Left-click on the blue -
Intel Desktop Board D845GVSR Product Guide (PDF)

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
(I would advise upgrading to Adobe Reader X { 10 }, however, if you don't have it )

After you click on the above link, it may take up to 30 seconds before the first page comes up. (Took 6 seconds just now. Adobe Reader X, and medium speed DSL connection)

At the top of the PDF file, is the PDF file page number box.
It is to the left of the Down Arrow.
Go to Page 11.
T is the Front Panel USB header.

This is where the USB ports on the front of the computer, (Front Panel) connect to.

Go to Page 31.
E is the Front Panel USB header.
The Front Panel USB header is J9F2.

Observe the numbers next to the pins.
Go to Page 33.
This is the pinout for the Front Panel USB header, using those contact pin numbers.

1, 3, 5, 7, and 9 = one USB port
2, 4, 6, 8, and 10 = one USB port

Notice pins 9 and 10 are not used.

You can connect two USB ports to this header.

The pinout of ANY USB connector, female, or male, is set to a Standard.

This is the standard pinout for USB connectors,

http://pinouts.ru/Slots/USB_pinout.shtml

In case you cannot download the Intel D845GVSR motherboard manual;

Looking at the motherboard in it's normal position, installed into the computer case, the USB header is on the Bottom edge of the motherboard.

It is to the immediate Right, of the bottom white PCI slot (PCI 3)
It is to the Left of the motherboard mounting hole.
It is Below the Intel 82801DB, Southbridge chip.

Two rows of pins.
5 across the Top row, 4 across the Bottom row.

STARTING on the Left side, (Towards the white PCI slot), and going towards the Right, the pins on Top are numbered,
Pins 2, 4, 6, 8, and 10

STARTING on the Left side, (Towards the white PCI slot), and going towards the Right, the pins on Bottom are numbered,
Pins 1, 3, 5, and 7

Pins 1, 3, 5, and 7 = One USB connection
Pins 2, 4, 6, and 8 = One USB connection

Pin 9, and Pin 10 are Not used. (N/C. No Connection)

A) Pin 1 is for Power

B) Pin 3 is for D-
The Data, or Signal wire. It is the Negative connection

C) Pin 5 is for D+
The other Data, or Signal wire. It is the Positive connection

D) Pin 7 is for Ground

Going to the other USB header;
A) Pin 2 is for Power

B) Pin 4 is for D-

C) Pin 6 is for D+

D) Pin 8 is for Ground

For additional questions please post in a Comment.

Out of curiosity which eMachines is this?

What's a good replacement for Dell Dimension 4700 speakers (AS500PA) that crackle too much to turn on?


The best replacement would be a Mac. They are easy to use, take up less space than that big tower, have a beautiful screen, and only one cable, (if you use a wireless mouse and keyboard). Not to mention, with the new operating system, Snow Leopard, you can run Windows with the help of Boot Camp!

And how much are those old Windows headaches worth to you? Believe me, I had PCs for over 20 years, and just converted to the Mac. It's like night and day. No more Windows headaches, my computer is actually fun again!

Will not work on my new dell computer


I'm not familiar with this speaker. Your sound card has a very low output which requires amplified speakers, so if the Bostons don't have an internal amplifier you won't be able to hear them.
