Appendix D. Updating the
operating system and firmware
Campbell Scientific updates data logger and CELL200 series operating systems (OS) as new
features are developed and bugs fixed. It is recommended that before deploying instruments,
you check operating system versions and update them as needed. This section applies to
updating the CELL200 series module operating system. Refer to your data logger manual for
information on updating its OS.
The CELL200 series itself uses two operating systems. The first is the Campbell Scientific CELL200
series operating system .We will refer to that as the CELL200 series OS. The second is contained in
the cellular radio module; we will refer to that one as the module firmware. One or both may
need to be updated from time to time.
CAUTION:
To prevent data loss, collect all data from the data logger before proceeding to update the
data logger operating system and cellular module firmware.
Updating the module firmware is done over the air (OTA), even with a direct USB connection to
the data logger. Therefore, it can take from 5 minutes to several hours depending on signal
strength between the cell tower and the CELL200 series, cellular network congestion, and OTA
server availability. OTA updates use some of the cellular device data plan for each attempt. Care
should be taken to plan accordingly to avoid cellular data plan overages.
D.1 Using the web interface
(cell.linktodevice.eu)
NOTE:
Instructions in this section assume that the steps in Pre-installation (p. 2) have been
completed. Cellular service must be setup before web access using
www.cell.linktodevice.eu/ is available.
NOTE:
This section applies to modules set up in serial server mode with a public static IP account.
