6.5 Run the PINGME.C Sample Program
Connect the crossover cable from your computer's Ethernet port to the RCM3750
module's RJ-45 Ethernet connector. Open this sample program from the
folder, compile the program, and start it running under Dynamic C. When
TCPIP\ICMP
the program starts running, the green
indicate an Ethernet connection is made. (Note: If the
not be using a crossover cable, or if you are using a hub perhaps the power is off on the
hub.)
The next step is to ping the board from your PC. This can be done by bringing up the MS-
DOS window and running the pingme program:
ping 10.10.6.100
or by
Start > Run
and typing the entry
ping 10.10.6.100
Notice that the yellow

and write a summary message on the screen describing the operation.

Users can change the status of the lights from the Web browser. The LEDs on the Proto-

The optional LCD/keypad module (see Appendix C) must be plugged in to the RCM3700
Prototyping Board when using this sample program. The sample program
implements a Web server that allows e-mail messages to be entered and then shown on the
LCD/keypad module. The keypad allows the user to scroll within messages, flip to other
e-mails, mark messages as read, and delete e-mails. When a new e-mail arrives, an LED
(on the Prototyping Board and LCD/keypad module) turns on, then turns back off once the
message has been marked as read. A log of all e-mail actions is kept, and can be displayed
in the Web browser. All current e-mails can also be read with the Web browser.
