Update Connect Sensor+ firmware from Digi Remote
Manager
This section describes how to update the Connect Sensor+ firmware. The Connect Sensor+ firmware
should be updated before updating the cellular modem firmware.
The update process is initiated from the Digi Remote Manager. It requires a working cellular
connection. It does not require physical access to the device.
Prerequisites
nRemote manager account
nDevice ID of the Connect Sensor to update
nConnect Sensor firmware update file
nModem firmware update file name
Step 1: Open Remote Manager
1. Open a web browser and navigate to Remote Manager.
2. Log into your account.
3. Click Devices in the menu on the left side.
4. Find the device ID for the Connect Sensor+.
5. Click the device ID to open your device. The Device ID looks like this string: 00010000-
00000000-03566100-72829951.
6. Check the Firmware Version of the device. Connect Sensor+ firmware version 2.1.1.3 or later
is needed to update the modem firmware.
nIf the firmware version is 2.1.1.3 or later, you do not need to update the firmware. Skip
to updating the cellular modem firmware: Update the cellular modem firmware over
the air (FOTA).
7. Review the Device ID, which looks like this string: 00010000-00000000-03566100-72829951. It
contains the IMEI of the modem. Make note of the device ID. You will need the device ID later to
start the modem firmware update process.

The next time the Connect Sensor+ is scheduled to connect to Remote Manager, it will start the
firmware update process. To cause the device to connect immediately, press the Wake button on the
device.
Once started, the update will take a few minutes to complete. After the device completes the update,
it will reconnect to the Remote Manager the next time it is scheduled to do so.
Updating multiple devices
The above example shows how to update a single Connect Sensor+. More than one device can be
updated with a single Remote Manager request.
To update a list of devices, add their device IDs to <targets> in the request. For example:
<targets>
<device id="00010000-00000000-03566100-79000697"/>
<device id="00010000-00000000-03566100-79000698"/>
<device id="00010000-00000000-03566100-79000699"/>
<device id="00010000-00000000-03566100-7900069A"/>
<device id="00010000-00000000-03566100-7900069B"/>
</targets>
To update all devices in a Remote Manager group, add the group name to <targets>.
For example:
<targets>
<group path="my_group"/>
</targets>
