DXP HD 4K PLUS Series • Reference Information
74
The following is an example of an
invalid
Class C addressing scheme:
Device
IP Address
Matrix Switcher Control Software computer
168.192.180.41
DXP HD 4K PLUS switcher
192.168.180.42
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 DXP 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 DXP switcher.
Ping to determine Extron IP address
The Ping utility is available at the command prompt. Ping tests the Ethernet interface
between the computer and the DXP switcher. Ping can also be used to determine the actual
numeric IP address from an alias and to determine the web address.
Ping the switcher as follows:
1.
From the Windows
Start
menu, select
Run...
. The
Run
window opens.
2.
In the
Open
text field, enter
command
.
3.
Click
OK
. A command window opens.
