Hi does anyone know PLX DAQ label directive?

I modified PLX DAQ demo to calculate and send sin angles to EXCEL by using XBEEs instead of USB serial. However I am not getting labelling on XBEEs. I am getting correct labelling on USB serial: TIME, TIMER, ANGLE, SIN.
I checked PLX DAQ Object Library but I am not sure what is wrong?

{{ ***************** Simple PLX-DAQ Example ***************** Simple PLX-DAQ routine for data. Plots the sine of angle from 0 to 360 degrees. Program will send data on serial port to be accepted and placed into an Excel worksheet. This example also demonstrates reading the current ROW from Excel, and starting over again once it exceeds 300. Check "Reset on Connect" to catch configuration data.
