Level Shifter
All of the Buffalo NAS devices have serial hardware built in, which they use for Linux kernel messages (console) as well as communication with the boot loader. While normal RS232 uses a nominal 12 volt for communication signals, the NAS's serial hardware signals are at 3.3v. It is therefore necessary to use a device which provides "level shifting" i.e. translates between the RS232 and 3.3v signal levels. The Terastations have this built in already, as a port designed to communicate with a UPS system however you will need to add one to a Linkstation or Kurobox.
The cheapest and most widely available level shifters are incorporated into some mobile phone data cables (see below), however slightly more work is required to determine the pin-out of these cables than if you buy some off-the-shelf converter kits.
Build your own LVTTL/RS232 or LVTTL/USB interface
- LVTTL/RS232 - Building a Custom Serial Interface
- LVTTL/USB - Use a Nokia Serial Cable on an ARM9 Linkstation
- LVTTL/USB - Use a cheap phone sync cable with the serial port
Buy a LVTTL/RS232 or LVTTL/USB interface
The cheapest TTL/RS232 converter uses a MAX232 with two serial channels for standard TTL 3V input. | The cheapest TTL/USB converter uses a chip by FTDI (the same chip is used in the SCON-KIT ) |

This board is made by Futurelec, however the order is shipped from Thailand so it takes 2-3 weeks to get it.
You'll also need some headers and connectors |
This cable is made by FTDI, but the pinout at the connector end would need to be reassigned. Spec Sheet w/ pinout, wire colors & other info |
