Keithley 487 through Agilent E5810A LAN/GPIB Gateway

[neni]

Hello,

I need to comunicate to the 'Keithley 487' through the Agilent Technologies E5810A LAN/GPIB Gateway.
I have allready installed the Keithley 487 VI on my labview 8.5.
I comunicate with the keithley 487 sending commands directly to the browser on Agilent IP.
When I add to MAX the new device it say to me that the 'succesfully opened a VISA session to ...' and about the device information appear the value of Current as manufacturer information.
The problem appears when I use the drivers in the Labview VI: the drivers are thinked to comunicate directly to a GPIB.
I trailed the device from the MAX and the icon appears but don't speak well to the keithley drivers. I need something that give to the Keithley VI the correct address, I suppose.
Could you help me, please?
Thanks a lot

It sounds like your Keithley is defaulted to using the LAN since that would be what would be used when communicating to it through a web browser which you claimed to have done first.

Is there some sort of setting to switch back to GPIB?

The Keithley has only GPIB connection. I've connected the GPIB output to the LAN/GPIB gateway (Agilent E5810A) and sent to the GPIB gate directly the commands reported in the Keithley datasheet and all is ok.

In this way I have connected my laptop through the browser writing the Agilent IP address directly to the Agilent LAN/GPIB gateway internal software and through the software interface I can speak with the Keithley insert the Keithley commands (see attached figure 1).

My problem with LABVIEW is that the vi driver of the Keithley need to have some additional information related to the interface communication between the Agilent LAN/GPIB gateway and the Keithley (something like an additional VI?). I’ve thought that this kind of connection could be given automatically using the MAX establishing connection as in attached figure 2 but doesn’t work.  Have you an idea as I can solve my problem, please?

Thanks a lot

I have no idea what you are doing. The VISA resource address string in the second JPG you attached for a VISA Open is not right.

If you are using GPIB, the resource address string should be something like GPIB::1::0::INSTR. If you are using TCPIP the address string is something like TCPIP::10.0.32.48::INSTR . You have a mishmash of both.

I could use E5810A very well when I added this equipment on MAX. Take a look to the following link a try to go step by step
