Updating and Resetting

Updating firmware

Resetting to factory settings

Atlona has made field firmware updating easy. Simply download firmware from Atlona.com and
upload the file to the matrix.
NOTE: Only use a Windows computer to update the matrix. Use of an Apple computer to update
will cause the matrix to be unusable until the update is redone with a Windows computer.
Atlona understands that settings can be troublesome and at times its just easier to set things back
to factory settings. To make things easier a simple one step reset was created.
To reset the matrix, hold down the buttons 1 and 4 while powering on. If successful the matrix will
be back to factory settings when it turns on.
Needs:
• Verify the current firmware version
• RS-232 9 Pin to 9 Pin cable.
• PC (not compatible with MAC)
• OS that supports USB mass storage devices
• USB A to USB B cable (i.e. AT11008)
Preparing the Matrix:
• Unplug the power cable.
• Hold the Cancel button while plugging the power back in.
• Connect the USB B to USB A cable into the Matrix and the Computer.
Updating the Matrix:
The computer should auto detect the connection, if it does not, open the USB device from “my computer”.
• Click open in a new folder. (if auto run detects connection)
• Delete the file in the folder. (there should be only one file, if more, delete all files)
• Copy and Paste the new firmware file into the USB folder.
• Unhook the Matrix from the computer.
• Unplug the power cable from the AT-H2H
• Plug the power back in and start the matrix normally. Your update should be complete
If you wish to verify the new firmware, use the RS-232 command “Version”.
To view the current firmware use RS-232 command “Version” or front panel (see page 12).
