Open Visa Error with Xantrex Power Supply

[aschenk]

I'm trying to develop a simple VI to control a Xantrex XT power supplie. I have downloaded their drivers and intalled them. I get the following error when I run it

ERROR-1073807346 occurred at Old VISA Oopen Initialize.vi->Untitled1

Possible Reason:
VISA:(HEX0xBfff000E) The given session or object reference is invalid.

I'm using LV 6.0.2

I'm a newbie to this awsome package.

You could try replacing Old VISA Open with the VISA Open from the Instrument I/O>VISA>Visa Advanced palette. Also, you should have done a search for instruments in MAX (Measurement and Aotumation Explorer) and verified the instrument is visible on the bus (GPIB I assume). If it is, then you should have selected the instrument on the VISA Resource Name control and clicking the little down arrow on the right. This assures that the actual VISA Resource Name is correct and you haven't mistyped something.
