Chapter 3 Main Panel Window [MY4-AEC] 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. 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. 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 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. DME Designer Owner's Manual 189
