LAN communication with Agilent7890A

[remi_san]

Hello,

I have a problem to get a communication with 2 Agilent 7890A GCs using LabView. I can ping them using their IP adress on my local network, it's ok.

but when I use MAX, it sounds that the GCs are not on the local network. MAX doesn't see them. I guess it's a problem with the VXI 11 / LXI protocol (probably the GCs are not using the same communication protocol). Still I can't get any communication. Is there any solution on this issue? Does it exist a driver that I didn't find yet or anything else?

Thank you very much for your help.

best regards,

Remi Dallmayr.

Does the computer with MAX have the same subnet as the instrutment?  If not, they are not in the same local network.  In MAX, have you tried to add the device by providing the whole IP address?

What do you mean by same subnet? Do you mean the same subnet mask?
well, my computer subnet mask is 255.255.255.0, how can I check the subnet mask of my GCs? I didn't expected it could come form the mask.,

In MAX, do you mean doing a manual entry of LAN Instrument? What do you mean by "whole IP adress"?
The adress I filled is, in my case and for my 2 GCs, it's 10.1.1.101 and 10.1.1.102 (my computer's one is 10.1.1.100 in this local network).
then, the Ressource Name created by MAX are "TCPIP0::10.1.1.101::INSTR". And then, when I finish adding this new device, I got a message telling me that MAX was not able to succefully open a VISA session to the device (Error VI_ERROR_RSRC_NFOUND, device not found..).

Does that help you to help me?
hope so.

regards,
remi.

And what happened when you tried the RAW option?

[remi_san]

I don't know this RAW option in MAX.. I just tried to figure it out, but I didn't find what is this and how to use.

If you could please develop your idea, maybe it can give me a solution.

thank you very much,

remi.

When you first select to create a TCP/IP resource, you are given three options - Auto Detect, Manual Entry of LAN, and Manual Entry of Raw Socket. The first two are for VXI-11 like it says. What is different about your screen?

[remi_san]

Ok, I get it.

Well, it's exactly the same. MAX doesn't find my device..
