OJM-OTX-XXX-KFMSAKeyfob Transmitter

DESCRIPTIONThe Linx MS Series Keyfob transmitter isideal for remote control and command appli-cations. Available in 315, 418, or 433.92MHzversions, it has been pre-certified for FCCPart 15, Industry Canada, and European CE(433MHz version only) compliance. Thisdramatically reduces development cost andtime to market. The high-performancesynthesized design provides superiorfrequency accuracy and minimizes bodyproximity effects. When combined with an LRreceiver, the keyfob can operate at distancesof up to 1,000ft. Ease of use and security aredramatically enhanced by the on-board MSSeries encoder, which allows instant creationof 16,000,000 unique addresses withoutcumbersome DIP switches or cut-traces.When paired with a MS Series decoder,keyfob identity can be determined and buttonpermissions established. The keyfob isavailable in 1 to 5 button configurations andcan be custom labeled.

The transmitter’s synthesized architecture delivers superior stability and frequency accuracy while minimizingthe effects of temperature and body proximity.The advanced MS Series encoder has several advantages over previoussolutions. It provides more security by offering 2 24 addresses, which is several orders of magnitude greater than older encoders. Furthermore, the address isinstantly established with a simple button press, eliminating cumbersome DIPswitches and cut traces. When paired with a MS Series decoder, keyfob identitycan be determined and distinct transmitter-receiver relationships established.The keyfob operates in the following manner: when a button is pressed on thekeyfob, power is applied to the internal circuitry and the encoder IC is enabled.The encoder then detects the logic states of the button data lines. The encoderdata is used to modulate the transmitter, which, through the antenna, conveysthe data into free space. The transmission cycle continues until the button isreleased. On the receiver side, a MS Series decoder IC is used to check thetransmitter’s address bits against the address saved in memory. If a match isconfirmed, and if the decoder has permission to recognize the specific buttonbeing pressed, the decoder’s outputs are set to replicate the transmitter’s buttonstates. These outputs can then be used to activate external circuitry required bythe application.The transmitter is compatible with the LC and LR product families. Forapplications where range is critical, the LR Series receiver is the best choice dueto its outstanding sensitivity. When the keyfob transmitter is combined with an LRSeries receiver and the MS Series decoder chip, ranges up to 1,000 feet arepossible. Appl ications operating over shorter distances will also benefit from the increased link reliability and superior noise immunity provided by the LR receiver. SETTING THE TRANSMITTER ADDRESS The encoder address is set by using apaper clip to press theCREATE_ADDR button on the boardthrough the hole in the back of thecase. When the button is depressed,an LED on the board will light upindicating that the address is beingcreated. The address will berandomized for as long as the button isheld down. When the button isreleased, the address is stored inmemory and the LED will begin flashingto indicate that the Control Permissions may now be set. Press the buttons thatthe transmitter will have the authority to access. Press the CREATE_ADDRbutton with the paper clip again or wait 17 seconds for it to time out and theaddress is set. The decoder will need to learn the address before it will acceptany transmissions. Please see the Typical Applications section of this data guideor the MS Series Decoder Data Guide for details on learning an address. BUTTON ASSIGNMENTS The keyfob is available in five unique button configurations. Those configurationsand the corresponding switch numbers are shown in the figure below. The tableshows which encoder data line has been assigned to each switch. When abutton is pressed, the data line will go high, causing the corresponding data lineon the decoder to go high if the addresses match.

575 SE ASHLEY PLACE ● GRANTS PASS, OR 97526 PHONE: (800) 736-6677 ● FAX: (541) 471-6251 6/17/2005 Compatible Electronics, This document contains information for the OTX-xxx-HH-KF#-MS Keyfob transmitter that is required for you to complete testing and filing for FCC, Industry Canada, and CE certification. We are requesting certification on three frequencies for FCC and Industry Canada (315MHz, 418MHz, and 433.92MHz) and one frequency for CE (433.92MHz). A brief description of the unit and its operation follows: The OTX-xxx-HH-KF#-MS Keyfob transmitter combines a synthesized archetecture OOK transmitter with an on-board encoder IC to form a simple yet effective RF remote-control transmitter. When a button is pressed on the remote unit, power is applied to the internal circuitry and the encoder IC is enabled. The encoder then detects the logic states of the button data lines. These states are formatted into a 2-word transmission cycle that continues until the button is released. The encoder data is used to modulate the transmitter that, through the antenna, conveys the data into free space. Once data is received, a decoder IC is used to check the transmitter's address against an address saved in memory. If a match is confirmed, the decoder’s outputs are set to replicate the transmitter’s button states. These outputs can then be used to activate whatever external circuitry is required by the application. The transmitters may need a modification of a level adjust resistor (R1) to tune the output power to the maximum legal limit. A map of the board showing the resistor location, schematic, and graph of output power vs. resistor value are included in this document and a kit of various value resistors has been included in the box with the units to be tested. Please inform us of what value will give us the maximum legal output so that we may use that value in production. All of the transmitters are wired for continuous modulated transmission upon inserting the battery by shorting one of the buttons. This has been done to make your testing easier and is not done in production. The worst-case duty cycle is 50%. The battery holder is marked with a “+” on it to indicate polarity. Should you have any questions about the units, please do not hesitate to call Ammon Gomez ( [email protected]) or Justin Hopper ( [email protected]) at 1-800-736-6677 or (541)-471-6256.

MS Series Encoder Data Structure The MS Series encoder is designed to securely register button presses or switch closures over a wireless link for remote contro l applications. It will turn eight parallel input lines into a secure, encoded serial bit stream output. The MS Series algorithm is designed to create a data stream with a 50% duty cycle by using the same number of high bits and low bits. Two wait times reduce this duty cycle to just below 50%.
