SV C BC P2 RF LF RF Engineer Aris Lambropoulos Tel: (248) 764-6771 aris.lambropoulos@siemen s.com 2. Module Housing The module assembly contains a bobbin assembly, a printed circuit board assembly, and a top cover. The bobbin assembly and top cover are a g lass filled nylon material, PBT -GF20. A four -pin connector and antenna ring are injection molded into the bobbin assembly. The PCB is 1 Oz. Copper, double sided, all SMD components will be affixed to the PCB by a double -sided IR reflow process. The PCB will mount to the housing via six press fit pins. The wire antenna is connected to the PCB by two of the six press fit pins. The top cover attaches to the bobbin assembly with four snaps and helps protect the wire antenna and PCB. .

SV C BC P2 RF LF RF Engineer Aris Lambropoulos Tel: (248) 764-6771 aris.lambropoulos@siemen s.com Characteristics: • Short circuit to ground and overload protections are provided • Maximum Low output voltage: 0.58V • Operating Current at Nominal Voltage (12.0V)= 12mA • Nominal Frequency= 15.625KHz • Minimum/Maximum Frequency= 14.843KHz/16.407 KHz 4.2.4 Serial Communication The transceiver is to communicate transponder data to the Control function using a 15.625 kHz +/ - 5% serial communications interface signal. The signal is to be in standard UART format with one start bit and one stop bit, and no p arity. The signal exiting the transceiver module shall be asserted low (ground). The serial communication will exactly mirror the transponder receive signal, except for the addition of diagnostic bytes and start and stop bits. This means that a transponde r "1" signal, as specified by the appropriate transponder ES, will correspond to a UART "1" signal .
