5. The analyzer attempts four cycles of communications with the indicated
LAN device.
6. The above message verifies that one way communication from the
analyzer to the network has been established
7. If the subnet mask was changed in step 2, set it back at this time.
How to Ping from the Local Area Network (LAN) to the Analyzer
Reverse communication should also be verified. Determining this, though, is
dependent upon your network setup and software. Generally, you need to
issue a ping command using the IP address of the analyzer to be tested. For
example, using Windows 95, 98, 2000, XP, or 7 and while at a DOS prompt,
type in ping xxx.xxx.xxx.xxx
panel. If full communication can be established, then the computer display
shows the cycle time for each of four cycle attempts (similar to that in step 5).
Other software may behave somewhat differently, but basically the same.
1. The letters x represent the IP address of the other device on the network.
2. The letters x represent the IP address of the analyzer.

d. At the prompt, type ping xxx.xxx.xxx.xxx
Enter on the front panel. Refer to Step 5 for the results of a
successful ping.
— It displays the time it took to complete each cycle.
— Each cycle times-out after one second if no communication is
established and the message, Request timed out, is displayed.
— It is common for the first of the four cycles to time-out even though
subsequent cycles pass.
— See below for an example output of a successful ping.
