Hardware and Software Architecture

This section describes the hardware and software modules of the radio and
Overview
their interaction in the functioning of the radio.
2.4.1 Hardware Architecture
The electrical hardware of the radio is implemented on a main board inside
the radio body and a control-head board inside the control head.
For a detailed description and block diagrams of individual circuits, refer to
"Circuit Descriptions" on page
The main board inside the radio body includes the following circuitry:
Main Board
The main board has an internal options connector which allows internal
options boards to access a variety of discrete and programmable signals.
For more information refer to
For a basic block diagram of the main board, refer to
page
For a more detailed block diagram of the transceiver, refer to
page 48
The control-head board includes:
Control-Head Board
For a block diagram of this control-head board, refer to
page
The control head has a concealed microphone inside the control head and
also has a provision for a separate circuit board that may be designed to
perform a variety of tasks including—but not limited to—Bluetooth
connectivity. No separate circuit board is required for a dynamic
microphone.
