Back To Update List

CR300 Series OS 2
Updated: 02-09-2016

  1. (CRITICAL) Upgrading the Operating System will reset all the CR300’s settings back to factory defaults. Sending this Operating System remotely is not recommended. To restore settings after the update, it is recommended that a backup be made of the current logger settings or take programmatic measures to ensure your settings can be restored. This can be done using Device Configuration Utility’s (DevConfig) backup utility or the CRBasic instruction SetSetting(). Watch the Video Tutorial: sending an OS to a Local Datalogger.
  2. (WARNING) The only TCP/IP instructions supported are DNP3, ModBus TCP/IP, PakBus TCP/IP, PPP, NetworkTimeProtocol(), TCPOpen(), and TCPClose(). Other TCP/IP instructions exist, but are in beta. Use at your own risk.
  3. Modified the operating system so that negative baud rates will now generate a compile error. The CR300 datalogger does not have the ability to do Autobaud.
