Pinging a Device
You can perform a simple test from your control computer to check that the MS9400 is responding correctly. To
perform the test, you will use a command called “PING” (Packet Internet Groper).
Performing a Ping
1. Click on the Windows Start button, and from the menu choose Run.
2. In the Run dialog box, type in the following:
ping xxx.xxx.xxx.xxx -t
Where 'xxx.xxx.xxx.xxx' is the IP Address of the MS9400 that you wish to test.
3. A 'DOS Window' will then open and show a series of responses as in the examples below.
4. To stop the ping command, press Ctrl + C on the keyboard.
Example 1: A successful Ping
If you have successfully 'pinged' the address 208.132.180.39, you will get the following response:
Reply from 208.132.180.39: bytes=32 time=2ms TTL=32
This response indicates that the device at the specified address is communicating correctly.
Note: The response 'time' value may vary according to network traffic.
Example 2: Unsuccessful Pings
If you are not successful pinging the address, you will get one of two messages. The message returned will
indicate the type of problem.
