We're using it as a backup server where it's important that it resumes its duties after a power failure. So we needed a circuit to automatically turn it on a short while after AC line voltage is restored after a power down from a UPS-signaled power failure or other power failure. It seems to work well, so we thought others might find it useful. text/html 2017-12-04T19:30:06+03:00 http://dns323.kood.org/hardware:fan?rev=1512408606 Fan Photos - In Context: Disassembly pictures[1 - cover off/best/3 wires][2 - exterior][3 - interior, in case][4 - interior, out of case] Variable-Speed Fan Details: Model ADDA AD0405HB-G73 Dimensions 40mm x 40mm x 10mm Voltage 5 volts dc Current 0.25 amperes Bearing Type Ball Blades 7 Wires 3 wires… text/html 2017-09-06T18:38:03+03:00 http://dns323.kood.org/hardware:gpio?rev=1504712283 The following information was deduced by reading the D-Link supplied DNS323 2.6.12.6 kernel source together with empirical reverse engineering.

Serial Connector Basics * The serial connector is at CON4, a white connector inbetween the two drive leds. * This is a 3.3V TTL serial port, common on many hardware devices. * You CAN NOT connect it directly to a PC serial port, you will need a level shifter, a popular (and simple) chip for this is the MAX232 * Warning: Do not use 5v signals - you might damage the CPU * TX is the outgoi… text/html 2017-09-06T18:38:03+03:00 http://dns323.kood.org/hardware:sound?rev=1504712283 This guide explains how to connect a generic linux-compatible USB sound card to the CH3SNAS/DNS-323. In this example, a Conceptronic USB Sound adapter was used. It is a thumbdrive-size usb-stick based on the C-Media CM108 chipset, and features a stereo in- and output jack. text/html 2017-09-06T18:38:03+03:00 http://dns323.kood.org/hardware:usb?rev=1504712283 USB Hacks/Mods * How To Mount an External USB Drive to your DNS-323 * Forum: USB Hub Hookup, Multi-Device Connections!
