Operation
files from a .pcm (PCM) format file, that are encoded and then decoded to a PCM file at a data rate as
indicated by the rate index number that follows the -r. For example, dvsi-r37.pcm is a PCM file
encoded/decoded at rate index 37 which is a data rate of 2400bps.
<file name>-r<rate index #>.pcma -- (encoded/decoded a_law file)
files from a .pcma (a-law) format file, that are encoded and then decoded to an a-law file at a data rate
as indicated by the rate index number that follows the -r. For example, dvsi-r39.pcm is an a-law file
encoded/decoded at rate index 39 which is a data rate of 3600bps.
<file name>-r<rate index #>.pcmu -- (encoded/decoded µ_law file)
files from a .pcmu (µ-law) format file, that are encoded and then decoded to an µ-law file at a data rate
as indicated by the rate index number that follows the -r. For example, dvsi-r42.pcm is an a-law file
encoded/decoded at rate index 42 which is a data rate of 4800bps.
In addition to the sample files several sample scripts are provided to facilitate testing operations.
Running the HDK Control Software
All Control of the HDK is performed using a command prompt window and a command line interface.
The file hdkcom.exe is the control program that is run for board set-up and operation. To run the
program, open a command prompt window and change to the directory (C:/hdk) that has the
hdkcom.exe program file in it and type in the desired command using the following structure:
hdkcom command description

where:
-q is an optional switch that may be use to prevent the DVSI Licensing Notice from being printed
to screen after the command has been processed.
[PC communications port settings]
Specifies which COM Port the HDK USB interface is using. See USB Connection Section for how
to determine the COM Port Value. This value is always followed by the Baud rate value and is used
in every command line.

[Interface Selection]
The interface selection option specifies which AMBE-3000™ Vocoder chip interface (UART or
Parallel) is used to connect to the MSP µcontroller. See Table 21 HDK AMBE-3000™ Interfaces
