WARNING: The preferred method of sending the operating system to the datalogger is by using the Send OS tab in the Device Configuration Utility. (All settings will be erased.)

If using File Control or the Connect Screen to send the new operating system, the user must stop the running datalogger program via File Control before sending the operating system.

Failure to stop the running program, when using File Control or the Connect Screen, may result in corrupt datalogger settings.

Dataloggers with corrupted settings will need to have the operating system resent from the Device Configuration Utility via the Send OS tab.

A stopped program will need to be restarted via File Control.


This download is for the CR6 datalogger. Execution of this download places the Operating System file(.obj) on your computer. It also updates the CRBasic Editor compiler and support files. 

Why Update? This OS contains new support for the Campbell Scientific CELL2xx external modems and bug fixes. Click the View Update History link below for details. With this OS update it is recommended that you also update the Device Configuration Utility to the most recent version so that new datalogger features are available in the utility.  

Note: Campbell Scientific always recommends updating operating systems on site if possible. When remote updates are required, it is recommended that you implement the necessary precautions to handle unexpected OS upload complications. All datalogger settings should be retained when updated remotely. If you choose to roll back to a previous operating system, the datalogger settings will be reset to default.
