Dual RS232 ports for separate data streams
-
25 mW transmit power (software selectable)
-
Up to 5km line of sight*
-
Up to 38,400 bps (software selectable)
-
Low power consumption with power saving modes

Applications
The RFI-433 is suited for applications in Utilities, Mining, Agriculture and Transport industries where reliable small area data transfer is critical.
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 Piccolo transparently moves data from end-to-end at speeds of up to 38.4 kbps. 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.
Specifications
| Variable Data Rate |
|
The radio modulation rate can be selected to accommodate for path interference and background noise. Users can select higher rates for shorter distances or lower rates for more reliable signal propagation in difficult environments |
| Frequency Hopping Spread Spectrum |
|
Users can select a particular channel or hop between frequencies in order to avoid jammed or occupied channels in the license free band. |
| Diagnostics at a Glance |
|
The front panel LEDs display diagnostic information indication such as Receive Signal Strength (RSSI), transmit power, radio temperature and RS232 port status. |
| Low Power Consumption |
|
With three different power saving modes and current draw down to 3mA, the Piccolo data radio is ideal for solar and battery applications. |
| Data Integrity |
|
User selectable Automatic Retry Request (ARQ) combined with radio CRC offers a high level of data integrity for end-to-end error free transmission. |
| Easy Network Configuration |
|
The Cruise Control software allows the user to configure, save and upload radio configuration settings. This allows for more efficient configuration of multiple radio modems. |
| Network Expansion |
|
The Piccolo radio can be configured for store-and-forward and mobile remote operation for flexible and expandable network coverage. |
