Question about Buffalo Technology Computers & Internet
This Buffalo NAS seems to be compatible only with UPS APC SU500J which is currently impossible to obtain outside Japan. Therefore Sub-D 9pin connector should use the communication protocol "smart comments" but I didn't find any information about this protocol !?
The user manual also describe Sub-D9 pin assignment and PIN 2 is describe as "APC_Line_Fail", PIN 3 as "APC_UPS_SHUTDOWN", PIN 5 as GND and PIN 7 as +12V. I have connected an other UPS model (whithout communication) to protect power supply of NAS. But I'd like to shutdown NAS anyway when UPS battery is empty. Can you help me to find solution to communicate with NAS ? Do you think I need to send specific ASCII code to NAS or is it only change of Electric level on PIN's which trigger the shutdown process ? Thank you to everybody.

SOURCE: Front panel connections
The most common problem for most people is knowing what wire color is positive & which wire color is negative. The colors blue, red, green, light blue, light red & light green are normally positive. The color white & black are negative. Your board uses only 2-pin connectors. The 3-pin power connector can be turned into a 2-pin connector to work with the M848ALU pins.
(Page 13, PANEL1). How to? Take the three pin connector, on the back side of the connector you'll see a small tab that holds the wire into the connector. Use a needle & pull tab up while pulling the wire out at the same time. The wire should slide out. Insert the wire back into the connector next to the other wire. You do not need to hook up the SUS led which stands for suspend.
Pin 1 is positive & the manual shows this by adding the _P = positive.
Pin 3 which is to the right of pin 1, is negative for the hard drive led. Pins 9 & 10 are not used.
Good luck sjcrofts!

Dell (Altec Lansing) A425 Subwoofer Pinouts
This is a standard female DB-9 serial port.
Here are the pinouts.
Pin 1 = Left Speaker Out +
Pin 2 = Left Speaker Out - (Common Ground)
Pin 3 = Left Line In +
Pin 4 = Right Line In +
Pin 5 = Left/Right line In - (Common Ground)
Pin 6 = Right Speaker Out +
Pin 7 = Right Speaker Out - (Common Ground)
Pin 8 = Power A
Pin 9 = Power B
Jumper (short) Power A to B to turn on.
If you want a volume control you need to put one on the inputs. You will buy buy a stereo volume control or potentiometer.
Here is some info on how to do this.

SOURCE: Need SPDIF pinouts identified.
When looking at the board, bottom towards you assuming that the 3 pins are parallel to the pci/e slots, the left pin should be the +5V vcc the middle pin is the spdif out and the right pin is the ground. Also the 3 pins are probably not exactly the same distance from each other (equally spaced) the 2 pins that are closest together are the spdif and the ground, spdif is always the middle pin. This info is based on 2 different asus motherboard install guides. I hope this helps you.
