I have windows 10 system. I was able to configure a power supply on a RS232 port and that is functioning.
I'm able to use Keysight Connection Expert to send commands or my applicaiton, no issues.
I have a 34405A DMM plugged in on USB.
Connection expert doesn't see it. Tried multiple cables and multiple 34405As.
I do see this, as if I'm missing a driver. See below. I installed driver_ivi_matlab_Agilent34405_1_1_1_0_x64 assuming that would help but it didn't.
But pretty surprised, the software has trouble with this DMM. It was easier to connect to a non-keysight instrument.
