SYSTEM DESCRIPTION This Standalone (SRx) receiver has to support the receipt of RF telegram from transmitted in free air way by corresponding transmitter and to transmit them to a host module (e.g. the Body Control Module and PIC module). ÿ KOR-baby board receiver 315, FSK -1K data rate based on Infineon TDA 521x , which module optimized maximum for the enhanced RF working range with LNA and data filter characterization. All receipts of RF telegram has to be transmitted to a host module with the serial linked communication line which line of single-wired serial link must be available to communicate with bi-directional for a bit rate 2.4k bauds for BCM for a bit rate 9.6k bauds for PIC. This SRx provide a variant 4 resistors with pull- Ground down for reading of mounted code. The processor of the SRx was selected as 8-bit Single-chip NEC’s Micro-controller with 78KO series The main function of generic SRx is ÿ RF signal detection (in-band) ÿ Data signal demodulation. ÿ Manchester and Shark protocol detection ÿ Self-polling for the standby current consumption ÿ Wake up function for the host module ÿ 315MHz RF data reception ÿ Serial communication with the single –wired link com. * For the operation of KOR-baby board is described separately.

It was located more than required distance away from the shielded room wall. Radiated Emission Testing was performed according to ANSI C63.4:1992 at the open field test site. The EUT was placed in a 0.8m high table along with the peripherals. The turn table was separated from the antenna distance 10meters. Cables were placed in a position to produce maximum emissions as determined by experimentation, and operation mode was selected for maximum. The frequencies and amplitudes of maximum emission were measured at varying azimuths, antenna heights and antenna polarities. Reported are maximized emission levels.
