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 Motorsports environments.


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


Radio Network Packet Protocol

The RFI-9256 is suited for Motorsports data, Telemetry applications, 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

The radios are also used in complex GPS systems

A more flexible alternative to WiFi or 4G networks.


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.
