General description of the RF transmitter
Honda SBRT is a UHF transmitter designed to be a gateway between a 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 seat units and monitor
the status of the sensors. The DUT will be attached below the car seats and
inside the cabin area. The number of SBRTs is different from vehicle to
vehicle (Figure 1).
The SBRT is going to work using a 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) is
activated, the SBRT is responding accordingly to the BCM on 433.92MHz.
