Hi.

 

I have connected the Keithley 2400 to my PC using a RS232-USB adapter, and my PC cannot identify the device.

On the device manager, it is not listed under COM, but instead it is listed as "USB-Serial Controller" as on the screenshot file below. NI MAX does not identify the device either. 

 

Can anybody help me on this issue?

It looks like the drivers aren't properly installed in windows.  What kind of RS232-USB adaptor?   

 

Each manufacturer of the RS232-USB adaptor usually provides its own Windows drivers you have to install.
