ReadString() get time limit exceed to complete operation error

I have a device name Time Electronics 5075. I am trying to use the SimpleReadWrite.2010 in National Instruments\NI-488.2\Examples\DotNET4.0\SimpleReadWrite\cs to comunicate with the device.

I can open the connection and send commands to the device by using this code

device = new Device((int)boardIdNumericUpDown.Value,(byte)primaryAddressNumericUpDown.Value,(byte)currentSecondaryAddress);
device.IOTimeout = TimeoutValue.T100s;
device.Write("X0/A1/F0{13}");

 But I am stuck at 

stringReadTextBox.Text = device.ReadString();

I get the error "Time limit exceeded to complete operation."

I don't know exactly should I add 

device.Write("T/D{13}");

before the device.ReadString() or not. But I get the same error for both cases.

Some info: Visual Studio 2010, Measurement Studio 2013, NI.488.2, Windows 7 Pro

Any idea?
