Determining whether devices are on the same subnet

To determine the subnet, the local device IP address is compared to the remote device IP

address (see figure 51). The octets of each address are compared or not, depending on the

value in the related subnet mask octet.

• If a subnet mask octet contains the value 255, the related octets of the local device

address and the remote device IP address are unmasked.

Unmasked octets are compared (indicated by ? in figure 51).

• If the subnet mask octet contains the value 0, the related octets of the local device and

remote device IP addresses are masked.

Masked octets are not compared (indicated by n in figure 51).

If the unmasked octets of the two IP addresses match (indicated by = in example 1 of

figure 51), the two addresses are on the same subnet.

If the two unmasked fields do not match (indicated by an unequal sign [≠] in figure 51,

examples 2 and 3), the addresses are not on the same subnet.

Updating the Firmware

Updates to the Extron WindoWall Pro Series Multi-Graphic Processor firmware are made

available periodically via the Extron Website. If the need arises, you can replace the

WindoWall Pro main firmware via an IP connection without opening the unit.

Determining the Firmware Version

There are three ways to check which version of firmware the WindoWall Pro is using:

view the System Status page of the WindoWall Pro embedded web pages, select About

WindoWall Pro... from the WindowWall Console software Help menu, or enter the Q SIS

command (to use SIS commands, see the Remote Configuration and Control section,

beginning on page 11).

Using the web pages

The WindoWall Pro comes from the factory with a set of default embedded web pages.

The System Status web page displays the firmware version of your unit, along with other

information such as your WindoWall Pro IP address and part number.

To use the web pages to find out the current firmware version number:

1. Connect the WindoWall Pro to a PC via an Ethernet connection (using a crossover

cable), or connect the WindoWall Pro and the PC to a network, using a straight-through

cable (see Rear Panel Features on page 6 for details).

2. Start a web browser program (such as Microsoft Internet Explorer).

3. Enter the WindoWall Pro IP address in the browser Address field.

NOTE: If your local system administrators have not changed the value, use the

factory-specified default, 192.168.254.254, for this field.
