2AS9T-ASRKET01RKE Transceiver

RKE TRANSCEIVER MANUAL FCC : 2AS9T-ASRKET01 ISED : 27298-ASRKET01 KC : R-C-Amo-ASRKET01 Description Features The RKE RF Transceiver acts as a control unit that transmits and receives RF signals sent from a vehicle key or smart key. After demodulating the received RF signal and performing digital signal processing, it interfaces with in-vehicle controllers to perform vehicle access control functions such as remote door lock/unlock, trunk opening/closing, and remote start CategoryItemDescription Product Information Product Name RKE Transceiver Manufacturer Amosense Application UHF Wireless Transceiver for RKE (Remote Keyless Entry) Wireless Communication Operating Frequency 433.92 MHz Frequency Bandwidth 25 kHz ~ 366 kHz Modulation Method FSK Antenna Type Ceramic Chip Antenna Power Specification Power Supply 12V Functional Summary Key Function UHF FSK Transceiver. Environmental Conditions Operating Temperature -40 °C ~ +85°C Operating Altitude 0 ~ 5000m How to install Recommaned mounting location is headliner. And position can be determined by evaluation result or sensitivity level(reception rate) - Set RKE and vehicle direction to 16 directions (22.5-degree intervals), numbering from 1 to 16. -Measure maximum reception distance (m) per direction -> A reception distance of at least 30 (m) must be obtained. RKE connector pin configuraration Functional Description The RKE Transceiver receives RF signals transmitted from the vehicle key FOB through an antenna. The received signal passes through a SAW filter and is then delivered to the RFIC (ATA5833). The RFIC demodulates the received RF signal using its internal Low-IF and digital DSP architecture, and transfers the demodulated data to the MCU (S32K312). The MCU verifies the received data and transmits it to the vehicle CAN network through the CAN Transceiver (TCAN1463), enabling communication with the BDC. During transmission, under MCU control, the RFIC outputs an RF transmission signal to the antenna, enabling two-way communication with the FOB or transmission of response signals. The RF transmit and receive paths are selectively switched through a switch. Power is supplied from the vehicle power source and converted to 5 V through an LDO (TPS7B8650). The 5 V power is then supplied to the RFIC, MCU, CAN Transceiver, and peripheral circuits. The unit is connected to the vehicle Local-CAN network through the CANH/CANL lines and transmits the received RKE-related RF data.

If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to correct the interference by one of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. FCC Caution Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Industry Canada Statement This device complies with RSS-210 of the Industry Canada Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Ce dispositif est conforme à la norme CNR-210 d’Industrie Canada applicable aux appareils radio exempts de licence. Son fonctionnement est sujet aux deux conditions suivantes: (1) le dispositif ne doit pas produire de brouillage préjudiciable, et (2) ce dispositif doit accepter tout brouillage reçu, y compris un brouillage susceptible de provoquer un fonctionnement indésirable. Industry Canada Radiation Exposure Statement This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 cm between the radiator & your body. Déclaration d’exposition aux radiations Cet équipement est conforme aux limites d’exposition aux rayonnements IC établies pour un environnement non con trôlé.
