why cannot connect

I have similar problem!
For more complete information, I want to reinstall my RB1100AH using netinstall (without losing configuration).
Tools that I prepared:
RB1100
UTP cable
Serial Cable (Female to Female)
USB to serial Male cable
Notebook (windows 7)
Netinstall 5.24 version

First, I use serial console to monitor routerBoard by connecting notebook via USB to serial and female serial to Routerboard. I use putty.exe for monitoring. It seems connected but the display appears blank. I tried to cut the power on routerboard and turn it on again but nothing happened. The display still appears blank.
The setting on putty:
Speed: 115200
Data bits: 8
Stop bits:1
Parity: none
flow control: XON/XOFF

Please somebody inform me how to solve this problem. :confused:
