- Maximum Air data rate: 224kbit/s.
- AES Hardware accelerated encryption.
- Optional RC PPM or SBUS Passthrough. (SiK firmware)
- GPIO Pin Mirroring capability. (SiK firmware)
- RF front-end filtering.
- ESD-protected and filtered IO pins.
- Firmware options available to achieve several network topologies including point-to-point SiK, Multipoint (MP) mesh and Asynchronous mesh.
- User updateable firmware and parameters
- License-free use in Australia, Canada, USA, New Zealand. (Depending on regional variants)
- Compatibility with ux series modems.
Note:
- The ux and x series modems are not compatible with older "a" or “+” series modems .
Compliance:
- Regional version modems are compliant with regional regulation
- NDAA compliant
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
Note:
- Regionally locked version of the modems may restrict or limit the performance and available parameter settings compared to the unlocked modems.
- Ultimately it is up to the user to identify the radio frequency regulation applicable to their areas of operation and ensure their modems parameters are set correctly.
