VISA error (VI and Picture attached)

[Matanlaza]

Hello,

 I wrote a simple program that remotely controls the Waveform Generator (Agilent 33250A) and by enabling controls on its output, the device is connected to the RS232 communication (com1).

I send a command that turns on the output and asks about his status (SCPI).

I'm trying to figure out who is responsible for this mistake and what timeout it is?

Did you search the forums for that error number before posting your question?  It has to be the most common error related to VISA communication.

It means you didn't get a response within the timeout period.  Why not?  Could be a few reasons, but a common one is that the command sent to get a response was incorrect or incomplete.  In your case it looks like you didn't use a termination character at the end of your command (usually a carriage return or linefeed) to tell the instrument that the command has ended and to send back the response.

No, I did not.

Thanks for your explanation!

I found a solution so maybe it would help others:
