Communication with RMX-4120

[michberk]

Hello everyone,

I am developing a HAL for some PSUs. Two of the functions in this HAL are: reading if the output is enabled or not, and reading the regulation mode (constant current or constant voltage) which the PSU is working with.

The problem I encountered is that in the driver of the RMX-4120 there aren't functions that return this information (or I haven't found them).

Since the communication with this instrument is via VISA, I could program it myself sending the corresponding commands, but the manual of the RMX-4120 does not have the commands to communicate with it. I'm a little bit puzzled because I don't know how to get this information. (Information that you can actually see in the display of the RMX).

Does anyone know how I could get this information programmatically? Or where I could find the specific commands to communicate with the RMX?

Thank you

Have you tried to query the according setting?

For Output Enable this would be likely: ":OUTPut?;"

Accordingly for Output mode: ":SYSTem:CONFigure:STARtup:PRIority?;"

Thank you so much! This queries worked!
