vxi/visa tcp (Newbie)

[mrmagoodleoo]

Hi,

I'm new here and new to VXI/VISA, I'm hoping somebody may be able to give me a gentle prod in the right direction 🐵

I have been tasked with writing an interface for a device which uses VXI over TCP, I have managed to use VISA to communicate with it, but I want the application that communicates with the device to be portable between PCs without having to reinstall VISA everytime, I tried copying the DLLs and the headers accross that are used by the app but when I ran it I got errors all over the place.

I am now looking into using only VXI but cannot find any documentation on how to do this, and the bits and pieces there are make it look like a mammoth task....which I'm sure / hoping it isn't ...

Can anybody help me ??

In the application builder you can select to add visa to the installer, so what are you afraid for?

What you are trying is 1)write a PC application that controls existing VXI-11 interfaced instrument? or 2)implement a device firmware that is compliant with VXI-11/LXI standard?

when case 1), you can simply use VISA library to control any VXI-11 instrument with using LabVIEW, CVI, C++, C#, VB, etc...

when case 2), you need implement RPC (Sun Microsystems' ONC-RPC) engine in the device firmware, because VXI-11 requires RPC as its lower layer. To implement this, you can use a 3rd party library or have to write RPC/VXI-11 wrapper codes over the TCP and UDP layers.
