Firmware Recovery

In the event of system errors, software corruption, or display issues, recovery firmware can be applied as a final troubleshooting step. By running the recovery firmware, the ENC4K16 Encoder will revert and default to an older version of its firmware, resolving most operational issues. Once the recovery is complete, the encoder firmware can be updated to the device’s current release version.

This article will outline how to prepare and use the recovery firmware for the DWC-ENC4K16 analog to IP encoder.

 

Supported/Affected Devices:

  • 16-Channel 4K HD Analog to IP Encoder (DW-ENC4K16)

 

Recovery Preparation

Required Files

 

Important Notes

  • Using the recovery firmware will reset the encoder to factory default settings.
  • The ENC4K16 does not support remote firmware updates/upgrades; the process must be performed locally.
  • You will need two (2) USB drives, each formatted to FAT 32 format.
    • USB Drive 1: Contains the recovery firmware.
    • USB Drive 2: Contains the official firmware.

**NOTE: The encoder will accept only one file on the USB drive at a time. If you do not have two (2), separate USB drives, you will need to take extra steps:

  1. Install the recovery firmware (only) on the USB drive.
  2. Use the recovery firmware on the encoder.
  3. Remove the USB from the machine and replace the recovery firmware with the official firmware (only).
  4. Insert the USB to the encoder and apply the official firmware.

 

Recovery Instructions

When applying recovery firmware to a DW-ENC4K16 analog to IP video encoder:

  1. Prepare the USB drives.
  1. Copy each firmware file (recovery or official release) to their respective USB drive.
  2. Ensure that the file is placed in the root directory of the USB and is not inside any folders.
  3. Ensure that there are no additional files or folders in the USB drives.

 

  1. Perform the System Recovery.
  1. Insert the USB drive with the recovery firmware (firmware98336_d2) into the encoder.
  2. Power the encoder OFF, then power the encoder ON.
  3. Wait for at least 15 minutes as the encoder:
    •  
      • Clears its configuration.
      • Repairs its kernel and file system.
      • Upgrades to the recovery firmware version.

 

  1. Downgrade to the Official Firmware.
    1. After recovery, the encoder will be upgraded to a beta version.
    2. Replace the USB containing the Recovery Firmware with the USB containing the Official Firmware (D4E_UI1P_240614_140_70237.release.fls).
    3. Using the local firmware update function, upgrade the encoder to the official version. then update to the latest official firmware version for the encoder.

 

  1. Remove the USB Device from the Encoder and update to the latest official firmware version for the encoder.
