Hello everyone,
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?
Best regards
Hi,
I don't have an E3643A, I tested rs-232 configuration and Connexion Expert on an E3634A, probably same or similar rs-232 interface. I didn't change anything in the software. This morning, I tested with the last version of Connection Expert and everything still OK...with an E3634A, E3633A, 6632B.
If you have another rs-232 equipment, verify if your cable is good on them. Each command must be follwed by LINE FEED character, verify that you have EOL sequence = "/n" in option of Interactive IO. If cable and setup is OK , maybe you have hardware problem with your E3643A.
