Software / GCS Support:
  • The software solution is an open source development called "SiK" . A boot loader and interface is available for further development and field upgrade of the modem firmware via the serial port.
  • Most parameters are configurable via AT commands, Eg. baud rate (air/uart), frequency band, power levels, etc.
  • V2.x firmware has been updated to support multipoint networking on the RFD900.
  • V1.x (non multipoint) is suitable for point to point links - the sourcecode is located at: Link
  • 3DR/RFD900 compatible configuration tool : Link
  • Integrated support for configuring the RFD900 radios is supported by APM Planner, with other GCS solutions in development.
  • The default settings are at 57600 baud, N, 8, 1, and 64k air data rate.
Software features include:
  • Frequency hopping spread spectrum (FHSS)
  • Transparent serial link
  • Point to Point, or Multipoint networking
  • Configuration by simple AT commands for local radio, RT commands for remote radio
  • User configurable serial data rates and air datarates
  • Error correction routines, Mavlink protocol framing (user selectable)
  • Mavlink radio status reporting (Local RSSI, Remote RSSI, Local Noise, Remote Noise)
  • Automatic antenna diversity switching on a packet basis in realtime
  • Automatic duty cycle throttling based on radio temperature to avoid overheating
Compliance:
  • The RFD900 is designed to be compliant with the following standards:
    • FCC Part 15.247 (Frequency hopping and digitally modulated intentional radiators)
    • AS/NZS 4268:2012 (Radio equipment and systems - short range devices)
  • The modem is designed for system integrators who will integrate the modem into their own projects and product prototypes.  The user is responsible for compliance with local regulations for radio transmitters.
Package Included:
  • 2 x RFD900x Radio Modems
  • 4 x Antennas, 900MHz Half wave dipole 3dBi
  • 1 x FTDI USB cable
