HT 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”).
HT Keyfob Transmitter Data Guide Description The Linx HT Series Keyfob transmitter is 1.00" S4 ideal for general-purpose remote control S1 S5 S3 2.23" and command applications. It has been S2 pre-certified for FCC Part 15, Industry Canada, and European CE (433MHz only) compliance, reducing development costs 0.45" 1.37" and time to market. Available in 315, 418 (standard), or 433.
Ordering Information Theory of Operation The HT Series Keyfob Transmitter combines a high-performance synthesized transmitter with an on-board encoder IC to form a highly reliable, yet cost-effective RF remote control transmitter. The transmitter’s synthesized architecture delivers outstanding stability and frequency accuracy while minimizing the effects of temperature, antenna port loading and mismatching.
Setting the Transmitter Address Contention Considerations The Keyfob allows the selection of one of 1,022 unique addresses. All keyfobs are supplied set to the same address. The address can be changed to avoid contention with other units or to create unique relationships. This is accomplished by cutting the traces. The traces are accessed by removing the rear cover. 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 315MHz and 418MHz versions are not legal for use in Europe. It has already been labeled in accordance with FCC, Industry Canada and CE regulations.
Receivers Typical Applications There are four options for receivers within the Linx product line. The first option is to use one of the OEM Function Modules, such as the Relay Module. These items are also pre-certified and can be immediately included in a product. Figure 10 shows a typical schematic using the LR Series receiver and the DS Series decoder. ANTENNA 1 2 3 The other options are to use one of the Linx receiver modules.
