Problem with UART?

Hey!

I wanted to connect to UART to see what boot messages im getting but so far i'm having issued with output. Im pretty much getting gibberish,
I would assume that is due to baud rate but i set it exactly to what documentation says 115200, 8 bit, none, 1, no handshake

I have pin out like this:
Tip -  TX
Rig -  RX
Rig2 - GND

I tried all boud rates and different tx, rx positions but no luck so far.

I used PL2303HX UBS-Serial TTL cable.

Can some one help me out?

Tnx
