The Micro-SX is normally configured for low-powered operation, sleeping to conserve power and with wake intervals defined by the user. The RTU requries a DC supply such as a solar panel, a bulk battery or plug-top supply. 

It regularly reports its status to a SCADA system using GPRS. The RTU also monitors its internal battery voltage, supplementary supply voltage, network signal strength and ambient temperature.
