The platform provides a multi-channel audio CODEC that supports and manages
all basic and optional
platform audio components. Developers can control internal and external speakers, microphones, and
Bluetooth and GSM voice functions using the API. When setting up these components, dedicated CODEC
channels are used to manage audio components, including system sound, voice calls, optional text-to-
speech, and voice recognition engines.

The platform provides two serial communication ports for external devices and peripheral connections.
These ports support various hardware and software flow control functions.
NOTES:
The Windows OS is not specified as a real time OS. Thus, it is highly recommended to
implement a flow control functionality using the serial communication to guarantee a
strong and stable communication flow of your application.

The platform provides a serial communication port at the EIA-Rs232 level. The port is connected to the
Main Terminal “Con1” connector, which is located on the bottom panel of the device. This port supports
a 300 to 115,200bps baud rate and provides one pair of communication-control handshake signals (CTS
/ RTS).
Generally, Serial Port 1 operates as a main system serial port for modem or AVL box communication.
