Did you implement the protocol on the Arduino?  You should have something similar to this:

byte sum = byte(val[0] >> 8) + byte(val[0]) + byte(val[1] >> 8) + byte(val[1]);
Serial.write(0x2); //Send sync byte
Serial.write(val[0] >> 8);
Serial.write(val[0]);
Serial.write(val[1] >> 8);
Serial.write(val[1]);
Serial.write(sum);

NOTE: I am not had the luxury of playing around with an Arduino, so fix any syntax errors I have introduced.

Then on the LabVIEW side, you do something similar to this:

Note: Notice that there are no waits in this VI.  The rate of data coming into the port will determine the loop rate.

Yes, my code is very similar and works fine.

Finally, it seems it works perfect!!

Thank you very much and I really appreciate what you did!
