Simulink Real-Time with RS-232 (receiving data)

I would like to model a Simulink project where my data is coming from RS232 (UART to USB) to MATLAB Simulink Real-Time model.

I would like to see the data passed on through my UART on a scope.

I have used baseboard RS232 parameter group is Board setup(com1/none).

Using MATLAB function ( DC = fcn(u)) and passing the u value directly to scope.

I am getting errors while building the project("External mode open protocol connect command failed").

Please find the attachments regarding error and my simulation below.
