900MHz High Speed Data Radio

The RFI-9256 radio is a license free frequency hopping modem in the 900MHz ISM Band, designed for long-range data transfer and reliable telemetry operation in industrial environments.

Features

900MHz License Free
  • Dual RS232 ports for separate data streams
  • 1 Watt transmit power (software selectable)
  • Up to 30km line of sight*
  • 115,200 kbps air data rate
  • Multi-mode LED front panel display for diagnostics, including RSSI meter
  • Protocol addressing and routing support, DNP-3, Modbus and IEC 870 compatibility

Applications

Radio Network Packet Protocol

The RFI-9256 is suited for applications in Utilities, Mining, Agriculture and Transport industries where reliable wide 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.

Telemetry applications include pipeline monitoring, pump station and tank control, irrigation, fan and pressure control, and environmental monitoring.

The radios are also used in complex GPS systems for fleet tracking and management, and high precision correctional systems for machine control and automation.

Specifications

Frequency Hopping Spread Spectrum    Users can select from a range of pseudo random hopping sequences to avoid interference in the license free band.
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.
Diagnostics at a Glance    The front panel LEDs display diagnostic information indication such as Received Signal Strength (RSSI), transmit power, radio temperature and RS232 port status.
Adjacent Channel Rejection    Superior receiver design enables good data recovery even in crowded spectrum environments by rejecting unwanted radio signals.
Easy Network Management    The user is able to view diagnostics and change the settings of other remote radios within a network from a single point.
Easy Network Configuration    The Cruise Control software allows the user to configure, save and upload radio configuration settings. This allows for multiple radios to be configured more efficiently.
