Connecting to a device on Company Network

[Speaks]

Hello,

I'm trying to set up and test communications in Max with a Power Supply that is on my company's network.

I am able to send SCPI commands over the network using the browser access available on the device, but I cannot get it to work in Max.  I have provided screenshots of the setup.

Any help is welcome.

Firewall might be blocking the ports used for VISA access whereas the webpage access is still allowed (Firewall doesn't know that the webpage is controlling the instrument)

You'd better check with your cyber people to make sure you are allowed to do this.

I'd guess the firewall too. I'd also think that having the ports on the device open to every PC and it's browser is far more insecure than just you and NI MAX - I think you have a security issue that needs resolving on the N/W the other-way around.
Get yourself a static IP on the instrument and your control PC and get IT to give firewall exceptions between the 2 and nothing else. (and get them to allow MAX to work) - you don't want a curious colleague hacking the Power level of a PSU in their lunch break!

Honestly you should not be doing this for several reasons. One of which you are seeing right now. Most IT people do not understand VX-11, therefor fear it and block it by default.

In our labs we have a completely separate "lab network" with its own internet connection that Engineering administers for testing and the corporate network with all the corporate security policies but "Never the twain shall meet"...

Also our ATE stations have their own mini network that is for VX-11 instruments only. (5 instruments a computer and a hub/switch) I hard set all the IP addresses on all the equipment, so I always know "where to find them". Our ATE stations also have WiFi that is used to connect to the "lab network" to share files and get updates

While not selected as the solution, this would be the ideal solution long term, but we are miles from there now. I will need to create a my own network for the time being.
