5.2.3 Run the
PINGME.C
Demo
Connect the crossover cable from your computer’s Ethernet port to the BL4S200’s RJ-45
Ethernet connector. Open this sample program from the
SAMPLES\TCPIP\ICMP
folder,
compile the program, and start it running under Dynamic C. When the program starts run-
ning, the green
LNK
light on the BL4S200 should be on to indicate an Ethernet connection
is made. (Note: If the
LNK
light does not light, you may not have 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 ping program:
ping 10.10.6.100
or by
Start
>
Run
and typing the command
ping 10.10.6.100
Notice that the orange
ACT
light flashes on the BL4S200 while the ping is taking place,
and indicates the transfer of data. The ping routine will ping the board four times and write
a summary message on the screen describing the operation.
