Re: Certification for JCI RSEVICPSI Transmitter/Receiver Model: RSEVICPSI FCC ID: CB2RSEVICPSI CANADA: to be provided by IC USER'S MANUAL INFORMATION (PRELIMINARY) The Vehicle User's Manual is in preparation. The following material will be contained in the manual: FCC ID: CB2RSEVICPSI CANADA: to be provided by IC This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry Canada. 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. WARNING: Changes or modifications not expressively approved by the party responsible for compliance could void the user's authority to operate the equipment. GENERAL This system provides the vehicle owner with compass, temperature, trip computer information, tire pressure information(PSI), and integrated Homelink. The Homelink and tire pressure portions of the circuit are separate from the compass section, except that the compass microprocessor controls the power to the Homelink section and the tire pressure section. The compass microprocessor also serially communicates to the Homelink/PSI microprocessor which switch has been pressed and the Homelink/PSI microprocessor communicates back the tire pressure information to the compass microprocessor for display to the driver. The following information refers to the Homelink part of the system and also to the PSI part of the system. Homelink Operational Description This system gives the vehicle owner the ability to use a garage door opener (GDO) that is integral to the interior trim of the vehicle. The Homelink shall be capable of learning and remembering variables required to emulate three different GDO transmitters. In the learn mode of operation, the user selects one of three channels. The Homelink determines the frequency, data and, where applicable, the Rolling Code manufacturer of the original GDO transmitter (OT). The frequency and data stream or rolling algorithm parameters (created within the OT's Rolling Code guidelines) are then stored in non-volatile memory (NVM) for use in the transmit mode of operation. Once contained in memory, the Homelink shall activate the given receiver by repeating, at the proper frequency, either a fixed data stream or a hopping data stream created with the OT's Rolling Code algorithm. Homelink Transmit Mode of Operation If a selected channel has been previously trained, the HomeLink shall operate in transmit mode. To operate the Homelink in the transmit mode, the user shall activate one of three transmit buttons. The Compass microprocessor shall determine which button has been activated and send the information serially to the Homelink microprocessor, which shall generate appropriate data at the proper frequency. The VFD indicator shall be ON continually during transmit mode. The VFD indicator shall rapidly blink (4Hz ± 10%) for 2 ± 10% seconds followed by continuous illumination during Rolling Code PWM transmissions. The HomeLink will continue in the transmit mode for twenty (20 ± 10%) seconds before proceeding to the learning mode of operation. Homelink Default Mode of Operation If a selected channel has never been previously trained nor previously erased, the Homelink shall operate in default mode. To operate the Homelink in the default mode, the user shall activate one of three transmit buttons. The HomeLink shall determine which button has been activated, and using a pre-determined identification code and frequency (see Appendix B for details) shall transmit such data with the VFD indicator continually on. The HomeLink will continue in the default mode for twenty (20 ± 10%) seconds before proceeding to the learning mode of operation. Homelink Rolling Code Default Mode of Operation The user places the Homelink in rolling code default mode by simultaneously holding down buttons one, two, and three for 30 ± 10% seconds. If buttons one, two and three are released while the VFD is rapidly blinking (< 10 seconds), all three channels will be cleared of data. When one of these channels is subsequently activated, the device shall immediately enter the learn mode of operation. To operate the Homelink unit in the rolling code default mode, the user shall activate one of the three transmit buttons. The Homelink unit shall determine which button has been activated and using a pre-determined code-hopping algorithm, bit period and frequency (see Appendix B for details) shall transmit such data with the VFD indicator rapidly blinking (4Hz ± 10%) for 2 ± 10% seconds followed by continuous illumination. Homelink Learn Mode of Operation The Homelink system can learn up to three (3) separate garage door opener (GDO) systems. To train a GDO transmitter to the Homelink system, the user shall complete the following steps: * select one of three channels by selecting 1 of three transmit buttons. If more than one channel is selected at one time, the Homelink shall give the lowest numbered channel highest priority. For example if channel 2 and 3 are selected, channel 2 shall have the higher priority. * hold a transmit button for twenty (20 ± 10%) seconds at which time the learn mode shall be indicated. The Homelink shall be in learn mode only if the VFD indicator is blinking at a rate of lHz ±10%. (The Homelink shall immediately enter learn mode if the selected channel is determined to be clear of data. See 1.2.4) * hold the present GDO transmitter near the Homelink. The Homelink shall train when the OT is held within 1 inch, and shall not train if the OT is held more than 3 feet away from the unit. Once in learn mode, the training process will be complete in <= 90 seconds and shall be indicated by rapidly blinking the VFD (4Hz ± l0%) 40 times. After completion the VFD indicator shall be off. * the data containing the frequency of operation and security code information shall be stored in non-volatile memory (N…

RS Electronic Vehicle Information Center  Module Description of Operation The RS module consists of three basic sections: the Electronic Vehicle Information Center (EVIC) section, the Homelink section, and the PSI section. The EVIC section provides data to the user via a dot matrix Vacuum Fluorescent Display (VFD). There are seven switches on board, four of which allow the user to change EVIC modes of operation, and three others, which allow the user to select Homelink operation. The EVIC microprocessor then powers up the Homelink section, and communicates to the Homelink microprocessor which channel has been selected. The Homelink transmitter is a radio frequency transceiver device whose primary function is to determine both frequency and bit code format of typical garage door remote control devices and identically re-transmit them to the original garage door opener receiver. The on-board microcontroller maintains the operational frequency band as 288Mhz to 418Mhz excluding forbidden bands of 240MHz to 285MHz, 322MHz to 335.4MHz and 399.9MHz to 410 MHz. The “training” operation is performed by scanning the legal frequencies with a single conversion superheterodyne receiver, looking for valid garage door opener bit code formats. In addition to being frequency and data format adaptive the Homelink transmitter is also RF amplitude adaptive. During the training sequence, the duty factor of the incoming bit code format is evaluated by the microcontroller determining the greatest amount of on-time in a 100 mS window. The duty factor is then used to mathematically adjust the output power in a range of 80% (1.9dB) to an upper limit of 30% (10.5dB) duty cycle. A 9 bit attenuator is adjusted by a closed loop power control algorithm in the microcontroller. After the training sequence the frequency bit code format and attenuator setting is stored in Non Volatile Memory (NVM) and retrieved on subsequent power ups. The VCO is set on the desired RF carrier frequency stored in NVM. The antenna is fine-tuned by sweeping twice around the expected tuning point. The voltage-controlled oscillator (VCO) is then modulated with the appropriate bit code information from the NVM. The basic function of the PSI system is to communicate the tire pressure information to the operator of the vehicle via the EVIC. The PSI system consists of two different sections. The first is a superheterodyne radio frequency receiver circuit built into the EVIC. This receiver interfaces with the EVIC to provide general tire pressure data as well as tire pressure-related messages to the driver. These messages include low tire pressure, high tire pressure, training messages, and general messages to service system when the tire pressure sensor transmitters are faulted or have a low battery. The second section is the tire air pressure transmitters that use a 433.92 MHz AM modulation radio frequency transmitter to communicate with the receiver in the EVIC. Each tire has one of these tire pressure sensor transmitters installed in the rims. The transmitters then communicate back to the receiver the pressure information and a unique id code from each tire. In order to train the PSI system to recognize which pressure transducer relates to which tire, the operator must first place the system in training mode via the EVIC. The display in the EVIC will then prompt the operator which tire to go to first. The operator can then take either a magnet or a 125 kHz transponder within close proximity of the pressure sensor of the tire indicated on the display. These tire pressure sensor transmitters will then send the appropriate message to the EVIC receiver identifying which tire is being trained. This process then needs to be repeated for each of the tires as prompted by the EVIC display.
