BeagleBoard Serial Problem

[bignick]

Ok so I installed archlinux on my sd card just like it says here: http://archlinuxarm.org/platforms/armv7/beagleboard

The board boots perfectly when I connect it via HDMI to my TV.
But when I connect via serial to the laptop, simply nothing appears on minicom or any other program.
I wired the serial connectors according to the following picture.
Any help is highly appreciated

Be sure you're using the right voltage, and that TX and RX go to the right places.

i'm using a 5v adapter 1.25mA, and using a serial to usb converter to connect to the laptop.
