Digi IX20
Digi IX20W Firmware
Digi EX/IX/TX-series devices running 24.3.28.88 or older firmware must upgrade to version 24.6.17.69 before upgrading to a newer firmware. Firmware version 24.6.17.69 is a step-firmware image for the EX/IX/TX-series product.
If your IX20W device revision is RevAM or newer, you cannot downgraded to a firmware version older than 23.6.1.105, otherwise the IX20 will not be able to establish a cellular connection.
Starting in firmware version 23.12.1.56, the watchdog system inside the Digi router will automatically re-power the cellular modem inside the Digi router if the modem is not initialized for more than one hour, and reboot the entire Digi router if the modem is un-initialized for more than 2 hours. Please read the release notes for information on disabling this option.
