VISA TCP/IP can not open session

[goodboycowboy]

Hi all!

I'm trying to made a communication between two computers through TCP/IP protocol. I create New VISA TCP/IP Resource, choose Manual Entry of Raw Socket, enter IP address and Port Number and have next error:

What is the solution to this problem?

[goodboycowboy]

Help me, please

Why don't you just use the normal TCP/IP functions? I'm not even sure you can talk to a non-VXI-11 device with VISA. You've got numerous TCP/IP examples, pick one.

VISA TCP will work with any generic TCP device.

Also, to the OP your resource name is incorrect. It should be TCPIP::<IP Address>::<Port>::SOCKET.

I think you're a bit confused.  Are you trying to do this?

You said you are trying to establish a communication between two computers, but in your example the client and the server address are the same. This leads me to think that you misunderstood the concept of creating a VISA resource. When you create with address x.x.x.x and port y, MAX tries to connect to that port as a client. It doesn't create a server.

The operation you are trying to do can be successful if there is actually a TCP server waiting on the same computer at port 50000, though.

Okay. I've never used the SOCKET type.
