2-6 Checking the connection with “ping”
Once you are finished with the network settings, make a check with “ping” to confirm that you can send and receive data normally. Here, “ping” is a network diagnostic tool incorporated into the OS as a standard feature. A simple description of how to use “ping” incorporated into Windows 98 is described below so refer to it when needed. If using “ping” while incorporated into another OS or TCP/IP protocol, then consult the instruc- tion manual for that particular device.
1)Click the “Start” button, point to “Pro- grams,” and then select
2)Run the ping command.
You will see a cursor at C:¥WINDOWS> on the screen. Enter,
ping xxx.xxx.xxx.xxx and press the Enter key.
In the xxx.xxx.xxx.xxx portion, enter the controller IP address.
The address for the controller in the fig- ure on the right (middle) is 192.168.0.2. This example shows normal communica- tion status.
3)The right (bottom) figure shows normal communication has not been established. If this happens, recheck the network de- vice and settings, and eliminate the trou- ble.
