The following problem: I want to establish a connection between E3643A power supply and PC via RS-232 cable. I am using the Keysight Connection Expert Software on a Windows 7 PC.
I can connect to the power supply and send commands.The problem is, I'm not getting any response.
Example: Send & Read *IDN?
Response ! VI_ERROR_TMO: A timeout occurred
Visa ErrorCode: 0xBFFF0015 (-1073807339)
Power Supply says Error – Query interrupted.
The same problem occurs with LabView.
What can I do to read data from my power supply via RS232 interface? E.g. voltage, current, identification?
