Update modem firmware by using a local firmware file

You can update your modem firmware by uploading a modem firmware file to your EX15 device. Firmware should be uploaded to /opt/MODEM_MODEL/Custom_Firmware, for example, /opt/LM940/Custom_Firmware.

Modem firmware can be downloaded from Digi here. Follow instructions on this page to determine the cellular module used by your device. After downloading, use tar or a similar unzipping tool to extract the firmware prior to uploading to the device. Note that the firmware file may not have a tar.gz extension, but it is a tar file and can be unzipped with tar or a similar tool. See Use the scp command for information about uploading files to the EX15 device.

  1. Select the device in Remote Manager and click Actions > Open Console, or log into the EX15 local command line as a user with full Admin access rights.

    Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.
