Can't access Powerconnect 5548p console using hyperterminal

I'm using the following to connect through console:

- USB SERIAL CONVERTER (RS232) Cable

- NULL MODEM ADAPTER KIT RJ45 to DB9F

- Tried CROSSOVER/ ROLLOVER CAbles

The USB Serial converter driver was installed correctly and was connected to COM3 but when I tried connecting using hyperterminal with the suggested settings:

- Select port: COM3

- Data rate = 9600 baud

- data format = 8 bits

- stop bit = 1

- flow control = none

- VT001 emulation mode selected

- function terminal key selected

But not showing anything in the terminal, any help? I really appreciate any inputs on this matter.
