NOTE: use the same COM ports in both RS232 Mainboard Setup and RS232 Mainboard Send block. If

they are different, unexpected results may occur.

The above model must be implemented on the second board to receive and display the square wave using

the serial link. You will find the RS232 Mainboard receive block in the library browser under xPC

Target> RS232> Obsolete V 1.0> Asynchronous. RS232 Mainboard setup and send block should be

configured as shown below.

After creating both the model files build them by pressing Ctrl+b while having windows of corresponding

models selected. Once the files have successfully been built, download them to their corresponding target

PC using TCP/IP. Make sure you have attached a serial cable between the correct COM ports of the

boards. Note down the fastest sampling rate with the baud rate of 9600 that the board can support.

Modify your files such that the square wave is looped back from the second board to the first and

compare the difference between the two waves you see on the monitor on the first board. This will help

you determine the delay in serial communication. The images below show you the two model files you

must build to complete this step of the experiment.
