3.3V TTY Serial Port
You will need a 3.3V TTL-Serial cable. I use an adapted Nokia CA-42 USB to TTL-Serial cable, but you can use whatever cable you want/have.
These little serial cables come in handy when working on embedded boards like this.
Here is some information on how to make a CA-42 into a USB to TTL-Serial cable.
The wire colors may be different, so be careful!
NEVER CONNECT THE WDTV SERIAL PORT (3.3V) TO YOUR PC SERIAL PORT (5V)!
WDTV Live serial port
You only need to connect the RX, TX, and Gnd. NOT THE 5Volt pin. CAREFUL!!

Tips
- When connecting the TTL cable try reversing RX/TX if you don't get the console.
- You can remove the top cover by pulling on it firmly to expose the inner PCB. Details in this video by b-rad: http://b-rad.cc/binaries/WDTV.Shell.Removal.AVI
