Execution of this download installs the CR1000 Operating System and Compiler on your computer.  It also updates the CR1000 support files for the CRBasic Editor.  

Note: This OS has crossed the 2 Meg CR1000 size limit for remote download.  The OS must be downloaded to the 2 Meg CR1000 via direct connect with the Device Configuration Utility.  All OS download methods are supported by the 4 Meg CR1000.

Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive.  This is due to a change in the format of the file system from FAT16 to FAT32.  In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32.  Any programs stored and running from the CPU drive will be lost.  It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.).  In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System.

Watch the Video Tutorial: Sending an OS to a Local Datalogger.

In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.
