5.2.3 Run the
PINGME.C
Demo
In order to run the demo program, edit the IP address and netmask in the
TCP_CONFIG.LIB
library to the values
10.1.1.2
and
255.255.255.248
for a direct
connection. Compile the program and start it running under Dynamic C. The crossover
cable is connected from your computer’s Ethernet adapter to the OP7200’s RJ-45 Ethernet
connector. When the program starts running, the green
LNK
light on the OP7200 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 10.1.1.2
or by Start > Run
and typing the command
ping 10.1.1.2
Notice that the orange ACT light flashes on the OP7200 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.
