Subnet Mask

The following is an example of an invalid Class C addressing scheme:

Device

IP Address

Matrix Switcher Control Software computer

208.132.180.41

 

 

DXP DVI Pro 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 “Pinging for the IP Address,” below).

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

 

 

See “Subnetting, a Primer” on page 130 for more information.

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 Microsoft 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.
