Continental Automotive 1 of 5 User Manual / Functional Description of the Continental Tire Pressure Wheel Unit Type TIS-04-ASK 315MHz
Continental Automotive 2 of 5 1. SYSTEM OVERVIEW Tire pressure monitoring system (called also TG for Tire Guard) is composed by: - a tire guard wheel unit including an integrated pressure, temperature and acceleration sensor and a RF transmitter. - a RF receiver unit (not described in this document) TG monitors the pressure of vehicle tire when driving or when it is stopped. An electronic unit (wheel unit) mounted inside the tire periodically measures the current pressure. Thanks to a RF link, this pressure information is transmitted to the RF receiver/decoder. 2. TECHNICAL DESCRIPTION Carrier frequency: 315MHz (± 32 kHz) Frequency FSK deviation: ± 40 kHz Number of channels: 1 Type of modulation: Amplitude Shift Keying (ASK) Baud rate: 9600 bds Rated Output Power: < 10mW Antenna: Internal Voltage supply: 1 Lithium battery 3V (CR2050) Voltage supply range: 2.1 up to 3.2V 3. TYPICAL USAGE PATTERN 3.1 AVERAGE FACTOR CALCULATION (Standard 47 CFR Part 15C (periodic intentional transmitter)) RF frames maximum duration = 10.3ms Averaging factor = 20 x log (10.3/100) = -19.7dB
