Hello,
You will need to create an array of U8 (or what ever data structure your
protocol requires)
with the proper values in each element. (82h, first element, commmand value,
second element, etc)
After you assemble the array use Byte Array to String to convert it so you
can pass it to the serial
port write vi.
Use String to Byte Array to convert it back to an array after you get a
reply from serial port read vi.
The convert primitives are in the Functions palette=>Numeric=>Conversion.
I use this method to send modbus messages to a controller over the serial
port.
Regards,
Alan Brause
