Updating Firmware

Updating Firmware#

The Printalyzer Enlarging Timer is designed to have firmware that can be updated. This is so that features can be added, and bugs can be fixed, after the device has shipped. The update process is designed to be relatively straightforward.

To update the device firmware, you will need:

  • The Printalyzer Enlarging Timer itself

  • The latest firmware file

  • A FAT32-formatted USB flash drive

Standard Update Procedure#

The update procedure is as follows:

  • Download the appropriate firmware file to your computer

  • Using your computer, copy the firmware file to a FAT32-formatted USB flash drive

  • Safely unmount/eject and remove the USB flash drive

  • Unplug any peripherals from the USB ports on the front of the Printalyzer Enlarging Timer

  • Insert the USB flash drive into one of the USB ports on the front of the Printalyzer Enlarging Timer

  • Press the ic_menu button, navigate down to the “Update Firmware” menu item, and press ic_menu again

  • Select the firmware file you want to install, and press ic_menu

  • Review the prompt, which will show the current and new firmware versions. If these look correct, select “YES” to continue.

The Printalyzer Enlarging Timer will now restart, install the new firmware version, and then restart again. There will be on-screen graphics showing the progress of this process.

Recovery Procedure#

Note

Before assuming that the Printalyzer Enlarging Timer is not able to start correctly, please make sure that the Blackout Switch is in the ic_blackout_off position.

In case the firmware update fails, and/or the Printalyzer Enlarging Timer is not able to start correctly, there is a recovery procedure:

  • Download the appropriate firmware file to your computer and rename it to DPD500FW.BIN

  • Using your computer, copy the DPD500FW.BIN file to a FAT32-formatted USB flash drive

  • Safely unmount/eject and remove the USB flash drive

  • Make sure the Printalyzer Enlarging Timer is turned off, and unplug any USB peripherals

  • Insert the USB flash drive into one of the USB ports on the front of the Printalyzer Enlarging Timer

  • While holding down the ic_menu button, turn on the Printalyzer Enlarging Timer

  • Wait a few seconds, then release the ic_menu button

The Printalyzer Enlarging Timer will install DPD500FW.BIN as the new firmware version, and then restart again. There will be on-screen graphics showing the progress of this process.
