The Control Panel allows users to verify the operation of the RS-232 serial communication interface
on the DE2i-150. 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 2-9.
2. Plug in a RS-232 9-pin male to female cable from PC to RS-232 port or a RS-232 loopback
cable directly to RS-232 port.
3. The RS-232 settings are provided below in case a connection from the PC is used:

Baud Rate: 115200

Parity Check Bit: None

Data Bits: 8

Stop Bits: 1

Flow Control (CTS/RTS): ON
4. To begin the communication, enter specific letters followed by clicking Send. During the
communication process, observe the status of the Receive terminal window to verify its operation.
