Firmware Upgrade Page
Extron may occasionally issue firmware upgrades for the VNC 325. See the Extron website,
www.extron.com, for details of the latest firmware release. Upgrades are supplied in a
single file, “upgrade_verx.x.tar”, where verx.x is the version number. Copy the upgrade
file onto the computer that you use to access the VNC 325 unit that is designated as the
controller.
Firmware upgrade is a multi-stage process, highlighted in table 10 and figure 42. The
detailed procedure begins on the next page. Extron recommends that all VNC 325 units in
the system be upgraded to the same firmware version to ensure full compatibility.

OK, you can then permanently install (commit) the new firmware. Up until the last stage it is
possible to return to the existing firmware version.
