Hi,I need to get access to connect a device via ethernet. I can connect to the device via IP address and port without any problem. But when I start sending SCPI commands through VISU the device does not respond. I am 100% sure that I need to send a certain command to enter the username. Username is anonymous. Please does anyone know how to send username to the device to allow access?

And in manual is described all about set username in Yokogawa but not how send this user name from PC to Yokogawa. I'm not sure where you looked but this seems quite clear (although a bit involved): This is from the download page for the WT3000E Series Analyzer I downloaded the 2018 version.
