Telemetry Transmitter Carrier Board (2003713-001)

Revision A
Theory of Operation: Telemetry Transmitter Carrier Board (2003713-001)
The Transmitter Carrier Board serves as the connection point for devices
used by the system. The remote mark, headphones, antenna, and battery
pack are all first routed through this board. Additionally, the transmitter
RF module and audio piezo speaker are located on this board. The
battery and external devices connect from the carrier board to the main
board through a 16-pin board transition header. A polyswitch current
limiter and polarity-reversal diode for the battery are used to protect the
circuitry on the Transmitter Board from improperly installed batteries or
component failures.
