User selectable Automatic Retry Request (ARQ) combined with radio CRC offers a high level of data integrity for end-to-end error free transmission. With three different power saving modes and current draw down to 3mA, the Piccolo data radio is ideal for solar and battery applications. The front panel LEDs display diagnostic information indication such as Receive Signal Strength (RSSI), transmit power, radio temperature and RS232 port status. Users can select a particular channel or hop between frequencies in order to avoid jammed or occupied channels in the license free band. Users can select higher rates for shorter distances or lower rates for more reliable signal propagation in difficult environments The radio modulation rate can be selected to accommodate for path interference and background noise. The low cost radio can also perform as a store and forward repeater to extend the range and can also be used with other RF Innovations radio modems and I/O modules. The Piccolo transparently moves data from end-to-end at speeds of up to 38.4 kbps. The data radio can be used in small scale telemetry systems, with almost any PLC, RTU, HMI or DCS vendor for monitoring and control of critical assets in SCADA systems. The RFI-433 is suited for applications in Utilities, Mining, Agriculture and Transport industries where reliable small area data transfer is critical. Protocol DNP-3, Modbus and IEC 870 compatibility
