How to generate a signal of fixed length of 6 bytes. The massage are transfered in 15ms cycle. Baud rate 38400, data bits 8, parity none, stop bits 1, CRC 16.
Example signal : AA 20 AA 02 IC IE.

See if one of the examples on the File Exchange will work for you:
Then if you run into problems ask a specific question and post your work.

I don't know what the "create and connect generator" does. Connect a constant source block to your Serial Send Block input. Give the constant block a value of 170 decimal, and configure its output data type to uint8.
As for the other parameters, it is your device. The header and terminator could be your STX and ETX characters. Blocking mode, you may have to try it with and without that checked to see what works best for timing.
Then when you are sure the serial port is sending out three bytes (STX + 170 + ETX), then make the middle part the full six bytes long using the mux block like I showed in my example.
