XBEE API MODE communication

I am using xbee s2c in api 2 mode to transmit data using LABVIEW to another xbee connected to xctu or arduino uno. I am able to write the frame on xbee connected to labview using VISA write function but it is not transmitting.

I am generating a hex array of the frame and then sending each element of array one after another like 7E then 00 then 10..using VISA Write.

Please help me to solve this.
