Using the PING Utility to Test an Internet Connection
PING ( P acket In ternet G roper) is a utility for testing whether a particular computer or
device is connected to the Internet by sending a packet to its IP address and waiting
for a response. The PING utility does not use TCP or UDP, but rather it uses another
transport-layer protocol called ICMP (
I nternet C ontrol M essage P rotocol). The
purpose of ICMP is to diagnose IP networking issues.
Once you have configured the Crestron equipment, you should “ping” each device to
verify the network connection. The PING utility is included with Windows, as well as
with Crestron’s 2-Series control systems. To ping a device with Windows, start your
Internet connection, open the Windows command prompt and type:
ping < IP address or fully-qualified domain name >
For example, you can type:
ping www.crestron.com or ping 164.109.174.244
A good connection will give the following results:
Pinging 164.109.174.244 with 32 bytes of data:

To use the Crestron Viewport (2-Series processors only), type the ping command at
the Viewport command prompt, i.e.,
ping 192.168.1.1 . Here a successful connection
will show:

No connection will show the following:
