ENVIROMUX-SEMS-16 FIRMWARE RELEASE NOTES
Last Update 2013/09/20

This listing provides the version number of the NTI ENVIROMUX-SEMS-16 Server 
Environment Monitoring System firmware file, the date of the release, and a 
summary of the changes in that release.

Note: Sensor configuration settings will be lost during a firmware upgrade. 
To save time, save a configuration file (see manual-page 52) before upgrading 
and reload the settings after the upgrade is complete. 

If you are upgrading from version 2.8 or earlier to version 3.2 or later, 
upgrade to version 3.1 first.  Then follow the instructions for updating the 
bootloader found on the firmware downloads page.  Once the bootloader is 
updated you will be ready to upgrade to any version 3.2 and later.

When updating Firmware, you must be logged in as "root" for the update to work 
properly. Also, after beginning the Firmware upgrade, do not shutoff or allow 
power to the unit to be interrupted.
