Exactly what the error message says....the device didnt respond within the 3 second time period.

How much data are you expecting back? If the read buffer looks complete then sometimes the terminator that signals the end of the transfer is setup incorrectly. Make sure the device is sending the equivalent terminator character.

If you are not getting any data from the read buffer then your most likely problem is that you need to append a termination character (such as carriage return or linefeed) to your Write function. In cases like this always check the communication in Hyperterminal (or similar) first. If it works it means you don't have your serial port configuration in LabVIEW setup properly.
