data acquisition using CR3000 through labview

hi all,

I'm new to Labview and VI stuff. actually i want to acquire temperature and relative humidity data using HC2S3-L probe connected to CR3000 micrologger. i need to connect this to labview. CR3000 is working fine i checked it through PC200W. 

I confirmed the rs232 connection through measurements and automation explorer it's present there and working OK. 

I think the problem is in my labview coding. i selected the right COM and options are OK for VISA configuration but i don't know why I'm not getting the data. the output i get is ZERO.

can you guys help me here? 

thanks
