Hi All,

[Farracillo]

Hi All,

I am trying to communicate with a switch that uses a CHECK BYTE as the last byte. According to the Manual the CHECK BYTE, or “longitudinal Parity”, is the exclusive OR on all messages bytes.

I am new in programming and I have no idea how to calculate longitudinal parity so I can not create the VI.

Can someone please help?

Like if my message in Hexadecimal is: 02 30 31 31 03   What would be the CHECK BYTE? And how can I calculate it?

Thanks a lot
