The Control Panel allows users to verify the operation of the RS-232 serial communication interface
on the DE2-115. The setup is established by connecting a RS-232 9-pin male to female cable from
the PC to the RS-232 port where the Control Panel communicates to the terminal emulator software
on the PC, or vice versa. Alternatively, a RS-232 loopback cable can also be used if you do not wish
to use the PC to verify the test. The Receive terminal window on the Control Panel monitors the
serial communication status. Follow the steps below to initiate the RS-232 communication:
