serial read write

[smot678]

hello,

I am trying to use serial i/o to communicate with a sensor.  The sensor waits for the Send command followed by a carriage return, then passes out its value.  I have attached the program I am using below.  I can get this to work using the instrument i/o assistant, but I would like to do it how I have it below.  The error I recieve is -1073807339 (VISA:  (Hex 0xBFFF0015) Timeout expired before operation completed.).  I have a feeling this is most likely due to the fact that it is waiting for data and never recieves it. I think the problem has something to do with it not recognizing my send command or the carriage return.

You're not sending a carriage return. You are sending the characters '\' and 'r'. Enable '\' Codes by right clicking on the constant.

Then using \ codes the control\constant must be put in that modus. Right click on the string and select '\' codes display
