Hi,
I am a beginner with Labview 2009 and am trying to interface my Keithley 2701 with an Ethernet connection. I can access the instruments internal web page and successfully use the interactive control panel so I don't think my computer is having a problem connecting to the instrument. When I run the Example VI's provided by Keithley/NI (obtained from the find instrument drivers) it works with a serial connection but when I connect with the Ethernet I get the Error: "Error -1073807343 occurred at VISA open in Keithley 27xx.lvlib: Initialize.vi". I have configured a TCPIP address through Keithley's configuration panel and the Keithley 2701 IP address shows up in the Example VI's as a port to communicate with yet fails when it tries to run the VI. If anyone has had any experience with this problem or may know how to solve it I would greatly appreciate the help.
Thanks!

Did you add the instrument in MAX? Devices and Interfaces>Create New>VISA TCP/IP Resource.
No idea what the Keithley utility is or does but the instrument has to be listed in MAX.

I have tried to list the device in MAX. However the following is given:
"VISA returned this static device when finding resources, and MAX was able to use VISA to parse the resource name. MAX was not able to successfully open a VISA session to the device."
The following post says the MAX has an issue connecting to TCPIP ports

I am currently trying to run the VI given in the page above but as of now I keep receiving the same error message.
Thanks.

I tried to run MAX again and used manual entry of raw socker using port 1394 for the Keithley and LabVIEW was able to recognize the instrument. So I guess that solves the problem for now!
