write multiple data serially in arduino

Hi everybody,

              I made a vi to send a multiple data serially to the arduino and my task is to send the swept step frequency manually to the arduino and the code is already uploaded in the arduino just i need to send values we wanted, got through the vi and send me the feedback and when every time you enter the values in control you need to press the enter button, so that the values can write into the arduino.

Thank you
