SI Keyfob Transmitter Data Guide
! Warning: Some customers may want Linx radio frequency (“RF”) products to control machinery or devices remotely, including machinery or devices that can cause death, bodily injuries, and/or property damage if improperly or inadvertently triggered, particularly in industrial settings or other applications implicating life-safety concerns (“Life and Property Safety Situations”).
SI Keyfob Transmitter Data Guide Description The Linx SI Series Keyfob transmitter is 1.00" S4 ideal for remote control and command S1 S5 S3 2.23" applications. Available in 418 (standard) S2 or 433.92MHz versions, it has been pre-certified for FCC Part 15, Industry Canada, and European CE (433MHz) 0.45" 1.37" compliance. This dramatically reduces development cost and time to market.
Ordering Information Theory of Operation The SI Series Keyfob Transmitter combines a high-performance synthesized SoC transmitter with an on-board microcontroller input interpretation. The transmitter’s advanced synthesized architecture delivers superior stability and frequency accuracy while minimizing the effects of temperature and body proximity.
Transmitter Address Contention Considerations The unique address for each unit is preprogrammed in the Silicon Labs radio IC during manufacturing and cannot be changed or modified by the end user. A 16-byte pairing key is programmed into the transmitter at the factory and is shared with the associated receiver during the pairing process. It is important to understand that only one transmitter at a time can be activated within a reception area.
Labeling / Instruction Requirements The transmitter has been pre-certified for FCC Part 15 and Industry Canada license-exempt RSS standards for an intentional radiator. The 433.92MHz version has also been tested for CE compliance for use in the European Union. The 418MHz version is not legal for use in Europe. It has already been labeled in accordance with FCC, Industry Canada and CE regulations.
