Q6. What is the fastest sampling time with 9600 baud in experiment 1.3 that the boards can tolerate? Why
is there a limit?
Q7. What is the delay from data goes from one serial port to another with the sampling time of 0.1
Q8. Change the sampling time to 0.01s and measure the delay again? What is the relationship between
delay and sampling time?
The final part of Exp 1.3 is where you send a command to the PC104 board via RS-232 and the board
performs compuations based on it. In order to do this download serialtest.mdl from blackboard. Build and
download to your target xPC.
Connect the serial cable to the COM port configured in the baseboard Serial F block to the COM port of
the host computer. Start the application on the PC104 board.
Download hyperterminal from blackboard and extract the files. Run the application.
