Update the firmware on an MY4-AEC Acoustic Echo Canceller card installed in a DME unit.
1 Select [Firmware Update]  [MY4-AEC] from the “Hardware” menu.
The “MY4-AEC Firmware Update” dialog box will appear.
2 Check the checkbox for the DME unit in which the MY4-AEC card to be updated is
installed.
Clicking the checkbox alternately checks and un-checks it. Click the [Select All] button if you
want to select all connected DME units. Click the [Clear All] button to un-check all connected
DME units.
3 Click the [Update] button.
The folder selection dialog box will appear.
4 Select the folder that contains the update file and click [OK].
The MY4-AEC update process will begin. The DME unit will automatically restart twice during
the update process. The update process finishes when the second restart has completed.
When the update process has finished it will be necessary to restart DME Designer.
NOTE
All connected DME units and MY4-AEC cards will appear in the “Device” column.
NOTE
The current MY4-AEC firmware version number is also displayed in this dialog box.
NOTE
Be carefully not to disconnect any USB or Ethernet cables, or interrupt the power supply during the update process.
Doing so can damage the MY4-AEC card and/or cause the DME Designer communication port settings to be lost.
NOTE
After the update check the firmware version number in the “MY4-AEC Firmware Update” dialog box to be sure that
the update has been successful.
NOTE
If insufficient [Remaining Memory] is available (the amount of memory available in the DME unit – page 111), it may
not be possible to complete the update process and an error message may appear in the Status field.
If this occurs you will need to delete unnecessary files (files stored using the DME File Storage function , libraries,
scenes) to make more memory available.
