GC6890 No connection RS-232

Hi,

I am trying to connect a HP6890 autosampler with GC chromatograph to a PC using the serial command port (RS232). I have hooked up the GC autosampler controller with a serial cable and then tried to connect and control the machine usinh HyperTerminal. However, I do not get any feedback from the machine whatsoever. 

Do you know what I am doing wrong?
