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.

Hi,

First, verify that your rs-232 cable is a null-modem cable (crossover), set you power supply on rs-232 (I/O config button), default setup is 8 bits, 9600 baud, no parity. I used it successfully, with Connection Expert Software on a Windows 7 PC 64bits. I hope this information can help you.

Hi,

I found the problem:

Apparently the rs232 cable had a defect. After the exchange the application runs without problems.

Thank you for your help!

Best regards
