MS 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”).
MS Keyfob Transmitter Data Guide Description The Linx MS Series Keyfob transmitter is 1.00" S4 ideal for remote control and command S1 S5 S3 2.23" applications. Available in 315, 418 S2 (standard) or 433.92MHz versions, it has been pre-certified for FCC Part 15, Industry Canada, and European CE 0.45" 1.37" (433MHz) compliance. This dramatically reduces development cost and time Figure 1: Package Dimensions to market.
Ordering Information Theory of Operation The MS Series Keyfob Transmitter combines a high-performance synthesized transmitter with an on-board MS Series encoder IC to form a highly reliable, yet cost-effective RF remote control transmitter. The transmitter’s advanced synthesized architecture delivers superior stability and frequency accuracy while minimizing the effects of temperature and body proximity.
Setting the Transmitter Address Contention Considerations The address is changed by using a paper clip or probe to press the CREATE_ADDR button on the board through the hole in the back of the case. When the button is depressed, an LED lights up in the MODE_IND window, CREATE_ADDR indicating that the address is being created. Button Access The address is randomized for as long as the button is held down.
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.
Typical Applications The Keyfob is set to 9,600bps, so SEL_BAUD0 should be tied high and SEL_BAUD1 tied low. The signal sent by the Keyfob transmitter can be received by the LR Series receiver module or the LT Series transceiver module. The receiver module is connected directly to the MS Series decoder, which decodes the transmitted signal. The decoder has several unique features, such as Latch Mode, Receiver Control and TX_ID.
