Niagara R2 UNC fails to start with a Fatal Error: Station not licensed - Invalid digital signature

Issue

A new Niagara R2 UNC is installed with a license. The license installs correctly. After a reboot, the station fails to start. The standard output window displayed a fatal error as illustrated below:

Product Line

TAC IA Series

Environment

Niagara R2

Cause

Certain foreign characters are not recognized by Tridium's License Generator.  In this case, a French character (with a symbol above the letter) was used in the customerSite name.  When the license was generated, the French character converted to a question mark (?):

customerSite=Rotondle des S?urs

The ? symbol is not recognized by Niagara.  So, when an UNC is rebooted, it will read the license file and stop when it comes to the customerSite name.

Resolution

Contact the factory to have the license modified.

After correction by the factory, the customerSite line in the license example above reads:

customerSite=Rotondle des Seurs
