Matrox Monarch Configuration

You can import the Matrox Monarch HD configuration on boot up from a web page. Go to:

Command Center > Automatic Configuration.
Type in URL Address starting with https.
Check "Load settings on device reboot."
You can either power off the device or hit reset.
Holding reset for more than 5 seconds does a factory reset.
On next bootup, device will have configuration contained from the remote file.
