CM Utility™ is a free configuration utility for MS-100 series weather station (CM-1 weather station controller). CM Utility runs on Windows computers and connects to the weather stations using the USB port. The utility also can be used to download the data log files. Additionally, the controller configuration files may be saved and easily copied to other units using the USB port on the weather station controller.
