Introduction - Campbell CR300 Series Application Note

1. Introduction

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.
This application note contains the procedures to update the firmware of the internal cellular
module used in the CR300 including model numbers CR300-CELL200, CR310-CELL200, CR300-
CELL205, CR310-CELL205, CR300-CELL210, CR310-CELL210.
Updating the cellular module firmware should only be done when directed to do so by Campbell
Scientific support or if cellular connectivity errors are happening. If the device is working there is
no need to update the firmware. Your data logger with cellular module will continue to serve you
and your application for many years to come.
The following procedures require data logger operating system (OS) version 08.01 or greater. If
necessary, update the data logger OS before updating cellular module firmware, see
update (p. 2).
These procedures do not work if using a PPP authentication username and password to connect
to the cellular network. The PPP authentication username and password are provided by the cell
provider and are required on specific cellular networks. You can see if you are using a PPP
authentication username and password in Device Configuration Utility
connection and Device Configuration Utility
that does not use PPP authentication, or have Campbell Scientific update the module firmware
at the factory. Refer to
(p. 15) for information on returning the data logger and module to Campbell Scientific.
Customers will pay shipping and handling fees but there will be no charge for the firmware
update service.
Updating the cellular module 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 module, cellular network congestion, and OTA server
availability.
This OTA update uses approximately 300 KB of the cellular device data plan for each attempt.
Care should be taken to plan accordingly to avoid cellular data plan overages. If you send the
data logger operating system via the cellular network as well, an additional 1.5 MB of plan data
usage should be planned for.
If you don't have direct access to the data logger nor a copy of LoggerNet
(p. 4)). If in this situation, either switch to a provider
