Agilent 34401A use USB to Serial RS-232 adapter - Error 1073807339

I am trying to measure voltage using the Agilent 34401A multimeter and acquire the readings using LabView 2011.  I connected the Agilent 34401A via a 

"USB to Serial RS-232 Adapter"  and found ATEN USB to serial bridge (COM9) from my PC. So I select VISA resource name is COM9. Please look at the picture.

Any ideas? THANKS>
