EZDT - Firmware Updates

If new firmware versions are released for any of these components, the files will be available on the documents tab on the website (see links below). They can be uploaded to the EZ-DT via a microSD card (32GB or less) located within the battery compartment (microSD card not included). To update the firmware of an ICC2 facepack or an EZ-DM decoder output module, use the ribbon cable connector located under the top cover.
