Continental SBRT UHF Transmitter User Manual
1. General description of the RF transmitter
Honda SBRT is a UHF transmitter designed to be a gateway between buckle switch and a sitting switch, which transmits wirelessly the status of those switches to the BCM, either upon a request initiated by the BCM using LF signal, or upon a status change of one or both switches. The term that Honda customer uses to describe such a transmitter is a Seat Belt Reminder Transceiver.
SBRT is part of a SMART system to locate seats units and monitor the status of the sensors. The DUT will be attached below the car seats and inside cabin area. The number of SBRT’s are different from vechicle to vechicle (Figure 1).
The SBRT is going to work using 433.92MHz working frequency band, covering the following two functions:
a.1st function, using 433.66MHz channel frequency. When an LF request is sent by the BCM, the SBRT is responding accordingly to the BCM on 433.66MHz.
b.2nd function, using 433.92MHz channel frequency. When one of the two switches (BSS- Buckle Switch Sensor or PSS -Passenger Sitting Switch) are activated, the SBRT is responding accordingly to the BCM on 433.92MHz.
