Common causes would be a need for internal testing, an unrecoverable software failure, or the need to revert back to a previous version of code due to a compatibility issue.


The procedure is as follows:

  1. Download the USB_Bootable_Ghost_Complete zip file from the Buildings Download Center.
  2. Download the zip file for the Encoder type that needs to be updated:
  3. Format a MicroSD card using the USB software downloaded in step 1.  Use the FAT32 filesystem setting and Create a DOS startup disk using the folder that comes with the USB software.
  4. Extract the following files from the Encoder zip file:
    .nbn file (located in root of .zip file)
    MLO and u-boot.bin (located in SD_CARD subfolder)
  5. Rename the .nbn file to firmware.nbn.
  6. Transfer firmare.nbn, MLO, and u-boot.bin to the root directory of the MicroSD card.
  7. With the encoder powered off, insert the MicroSD card into the MicroSD slot located on the motherboard of the Encoder.
  8. Power Encoder on, reimage process will begin immediately.  The 2nd LED from left to right will be on.
  9. When upgrade is complete (after about 15 minutes) the 3rd LED from left to right will turn on.  If re-image fails, the 4th LED will turn on.
  10. After re-image is complete, power off the device and remove the MicroSD card.
  11. Unit is reimaged and ready for use.
