The following is an example of an
invalid Class C addressing scheme:
Device
IP Address
Matrix Switcher Control Software computer
208.132.180.41
HDXP Plus switcher
192.157.180.42
NOTE: The above addresses are invalid because the network identifier for each address
is not the same even though each IP address is unique.
You can perform a test from your computer to check that a device at a particular address
is responding correctly or to determine its address (see
Subnet Mask
The subnet mask is another 32-bit binary number that is used to “mask” certain bits of
the IP address. This provides a method of extending the number of network options for
a given IP address. It works by allowing part of the host identifier to be used as a subnet
identifier.
It is important that you set the correct value for the subnet mask. The basic values
depend on the class of IP address being used.
Class Name
Subnet Mask
Class A
255.0.0.0
Class B
255.255.0.0
Class C
255.255.255.0

Pinging for the IP Address
To access the HDXP switcher via the Ethernet port, you need the switcher IP address. If
the address has been changed to an address comprised of words and characters, the
actual numeric IP address can be determined using the Ping utility. If the address has not
been changed, the factory-specified default is 192.168.254.254.
Ping can also be used to test the Ethernet link to the HDXP switcher.
Ping to determine Extron IP address
The Microsoft Ping utility is available at the command prompt. Ping tests the Ethernet
interface between the computer and the HDXP switcher. Ping can also be used to
determine the actual numeric IP address from an alias and to determine the web address.

1.
From the Windows
Start

Run...
. The Run window opens.
2.
