CWTWC1U283Passive Entry System (Tuner)

User’s Manual MODEL No.: TWC1U283 The radio frequency keyless entry system has the following functions. 1. Locking and unlocking the doors without mechanical key. 2. Sounding a panic alarm during vehicle is not running. This system consists of RF Tuner, transmitters, and BCM. The RF Tuner (EUT) is supplied 5V from BCM. It is designed to operate on a single fixed frequency RF 315MHz by amplitude modulation. It receives unique identification code and function code transmitted from transmitters. After receiving RF signal, demodulation IC in Tuner demodulates RF signal from transmitters. And then driving circuit in Tuner outputs the demodulated signal to BCM. ・Basic specifications  Operating supply voltage 4.5V ~ 5.5V  Operating supply current < 12mA  Stand-by current < 1.0mA  Operating ambient temperature -40 o C to +85 o C FCC CAUTION Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device complies with part 15 of the FCC 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. ・Radio Law of Thailand This telecommunication equipment conforms to NTC technical requirement.

Type of Equipment : Passive Entry System (Tuner) Model No. : TWC1U283 Serial No. : Refer to Section 4, Clause 4.2 Receipt Date of Sample : May 20, 2012 Country of Mass-production : Japan Condition of EUT : Production prototype (Not for Sale: This sample is equivalent to mass-produced items.) Modification of EUT : No Modification by the test lab 2.2 Product Description Model No: TWC1U283 (referred to as the EUT in this report) is the Passive Entry System (Tuner). Feature of EUT: This unit receives the RF output signal from the FOB (Transmitter) in response to several switch operations. This unit sends detected signal to the Controller through Signal and RSSI outputs. The Controller provides operations according to receiving signals. Clock frequency(ies) in the system : 29.5533MHz (Oscillator circuit) Type of Receiver : Super hetrodyne Frequency of Operation : 315MHz Oscillator Frequency : 29.5533MHz (Crystal) Local Oscillator Frequency : 315.235MHz (29.5533MHz x1/3 x32) Intermediate Frequency : 235kHz Antenna Type : Internal Antenna (Monopole) Method of Frequency Generation : Crystal Operating voltage (Inner) : DC 4.5 V to 5.5V Operating temperature range : -40 deg. C to +85 deg. C FCC15.111(b) The receiving antenna (of this EUT) is installed inside the EUT and cannot be removed (permanently attached). Therefore, Radiated emission test was performed.
