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 MGP Pro Series Multi-Graphic Processor firmware are made available
periodically via the Extron website. If the need arises, you can replace the MGP 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 MGP Pro is using: view the
front panel LCD window during power-on, view the System Status page of the MGP Pro
embedded web pages, or select
About MGP Pro from the MGP Series Control Program
Help menu.
Using the LCD display at Power-on
Watch the LCD window as you connect the MGP Pro to a power source. The first piece of
information displayed on the screen is the firmware version (along with the product name).
