VISA Read time out at serial communication.vi example in NI

[tatnin]

In hyperterminal (VT100), after I send a command, the respond is RSSI (dBm) -62. The respond in serial monitor tool (portmon) is Length 80:....[0m.[2J.[1;1H.[0M.[2J.[1;1H.[18; 1HRSSI (dBm).[18:29H] If I using NI example Serial Communication.vi to send the command and try to capture the respond. The VISA Read time out. If I monitor the serial port of the VI, there is nothing to read and time-out except the command that I just send. Why

Hello:

Try increasing the timeout interval to avoid that error. You can do this through Control Panel >> Devices >> select the card >> Properties (right-click) >> Settings Advanced >> Timeout interval.

Have you tried a loopback test? Here's a knowledge base (KB) entry resource that show's how to. If you go to ni.com >> Technical Support >> Knowledge base (option 3) >> and type in "Serial Communication Starting Point" you will get it.

Hope this helps. If you have any further queries, please let us know.
