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:

1. Choosing the RS-232 tab leads to the window in Figure 3-11.
