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.

4.2 Terminal Definitions and Characteristics
All inputs and outputs shall be capable to withstand any single point failure of a short to battery or ground,
through any resistive path, without phys ical damage to the component while the fault is occurring, and any
physical damage and/or functional degradation once the fault is removed. .

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 .
