R:Com is a tracking option for fixed terminal area communication and monitoring. R:Com uses a transmitter attached to the refrigeration unit microprocessor controller or datalogger. This transmitter passes information to a base station receiver, which provides information through a standard personal computer loaded with the R:Com software. Relay units can be mounted around the grounds of large distribution centers to extend the reach of R:Com.

R:Com can operate in an automatic mode, periodically broadcasting queries throughout the network. These queries detect refrigeration units that have arrived within the broadcast area since the previous query. When a new unit is detected, R:Com logs it onto the network and downloads any available information. The system also relays other information such as unit operating alarms to managers. If an alarm requires immediate action, R:Com sends an alert message in as many as four ways. It places a flashing icon on fleet managers' computer screens, sounds an audible alarm, sends urgent email alerts, and pages managers by cellular telephone.

R:Com is compatible with Thermo King microprocessor controllers starting with the MP-IV and its successors as well as DMS-III, DRS, DAS, and Accutrac dataloggers. The software runs as a normal desktop application on any personal computer using the Windows 2000 or NT operating system.
