prologix GPIB-LAN controller

[ku_ku]

Hello, I'we prologix GPIB-LAN controller, but I'm unable to enquire it in MAX.

1. I've connected it to LAN and I can ping it like in http://zone.ni.com/wv/app/doc/p/id/wv-1653 video the IP: 192.168.2.12 (the IP of computer 19.168.2.25)

2. in MAX add a VISA TCP/IP resource

3. choosing Autodetect instrument

4. I get: No VXI-11 LAN/LXI instruments were found on the local subnet

ofcourse, if I'm doing it manually It is not recognised by MAX

...any clues? how to troubleshoot this?

[Dennis_Knutson]

Nothing to troubleshoot. It's not a VXI-11 instrument and it is not supposed to be detected by MAX. That video does not apply at all. You need to follow the instructions from Prologix.

That's true.. it'snot a VXi   instrument

But I still can not solve a problem to communicate using LabView. I've got a Prologix  vi but still do not understand how to define that I should communicate to GPIB-ethernet controller where to put the IP of controller????

If I'm using Hiper terminal ewerything works fine

[Dennis_Knutson]

Have you looked at Prologix's web site? It says to use TCP/IP functions. Are you specifying the IP address with Hyperterminal?

[ku_ku]

Yes I have  studied the website of prologix, but I cant get how to get connection using LabView... esspecialy if I'm using VI delivered by Prologix.com????

Yes I specify IP address in Hyperterminal.

[Dennis_Knutson]

That VI is for their Serial converter. As I already said once before, their web site says to use the LabVIEW TCP/IP functions.

You just have to click on the FAQ link for this device.

I'm trying to connect LAbView with the Ethernet - GPIB Prologix device, but i can't. I followed the instructions in the web page, using TCP module, but it is impossible, the HP device i want to controll doesn't make any change. Although, there is not any ERROR message.

Additionally, I've used the command sequence i wanted to use in LabView, with the hyperterminal, and it works.

Did anyone find the solution for TCP communication with Labview and Prologix device ¿?' Thanks.

Hey Xakal,

Can you provide the LabVIEW code you are trying to use to connect with your Prologix device? Am I correct in my understanding that you can execute the commands in hyperterminal but when you use the exact same commands in LabVIEW you run into errors? This FAQ has some information on what may be happening with your device if it is not responding to commands:http://prologix.biz/gpib-ethernet-1.2-faq.html.  If it works in hyperterminal but not in LabVIEW then I suspect it is something with how you are setting up your TCP/IP commands in LabVIEW. Some information on doing this can be found here:https://www.ni.com/en/support/documentation/supplemental/06/basic-tcp-ip-communication-in-labview.ht....  Please post back with your LabVIEW code and any additional questions.
