1 Introduction
The Audio Codec Adapter is a simple and easy-to-use universal adapter board designed to
quickly evaluate the digital audio functionality of the supported Gemalto M2M (evaluation)
products. Using this reference adapter, it is possible to develop and test external audio appli-
cations for the supported Cinterion®modules (see Section 1.2).
This document1guides you through the process of connecting the Audio Codec Adapter cor-
rectly and getting started with the evaluation of the module’s audio functionality.
The Audio Codec Adapter is intended for use in test environments only. All persons handling
the Audio Codec Adapter must be properly trained in electronics and observe good engineering
practice standards.
The Audio Codec Adapter is a test/development board, and has not been designed to be em-
bedded into other products.

2 Audio Codec Adapter Overview
This chapter gives an overview of the available Audio Codec Adapters, i.e., MAX9860 in Sec-
tion 2.1 and NAU8822 in Section 2.2 employed by Gemalto M2M to evaluate the digital audio
interface functionality of the supported modules.
2.1 MAX9860 Audio Codec Adapter
The MAX9860 Audio Codec Adapter is based on the MAX9860 16-bit mono audio voice codec
from Maxim Integrated. The adapter board can be plugged to the DSB75 (or DSBmini) in order
to be used with a variety of Cinterion®modules (see Section 1.2), and supports the following
features:
The Audio Codec Adapter supports the following features:
• Directly connects to DSB75 (or Mini-DSB)
• Most important configuration settings are accessible via DIP switch
• Almost all configuration settings are accessible via RS232 serial interface
• PCM/I2S support
• BCLK = 256(only in slave mode), 512, 1024, 2048kHz
• Master/Slave mode
• 16kHz WB/8kHz NB mode
• Handset/Headphone support
• Short/long FSYNC2
• Sending DTMF sound sequences on analogue or on digital (long FSYNC Intel mode)
• Recognizing beep sounds by means of FFT on analogue or on digital (long FSYNC Intel
mode)
2.1.1 Interfaces
Figure 1 and Figure 2 show various interfaces on the top and bottom sides of the Audio Codec
Adapter.

AD converter output at bit 14.

2.1.2 Access
For update, configuration and programming purposes the Audio Codec Adapter can be ac-
cessed via the RS232 serial interface on its top side.
The RS232 interface on the Audio Codec Adapter can be connected to a PC’s serial port by
using a crimped cable that links the 10-pin connector at the Audio Codec Adapter to a 9-pin
connector at the PC. Such a crimped cable is shown in Figure 4:
Figure 4: Crimped serial cable
Once connected to the PC, the Audio Codec Adapter should be available at a defined COM
port for update, configuration, and programming as described in the below sections.
2.1.2.1 Update
Please complete the following steps to update the Audio Codec Adapter:
• Unzip the archive with the latest software for the Audio Codec Adapter to a directory on the
PC. The following files should be available: CodecAdapterMAX.bin, Sloadhost.exe, and
firmware_update_com_x.bat
• Call the batch file firmware_update_com_x.bat.
• Enter the COM port number the Audio Codec Adapter is connected at.
• Wait for a few seconds until the update is complete, and the adapter was reset, i.e., until
the LEDs were restarted.
Having updated the Audio Codec Adapter’s software, the adapter is ready to be employed for
configuration and programming.
Note: Coming from the factory, the above described update procedure is also required to ini-
tialize the Audio Codec Adapter before it can be used for the first time, i.e., before any of the
LEDs on the Audio Codec Adapter’s top side will light to indicate the adapter’s current status.

2.1.2.2 Configuration
There are two ways to configure the Audio Codec Adapter:
• Firstly, the hardware DIP switch can be used to configure the most important configuration
settings. See Section 2.1.1.1 and Section 3.1.1 for default and other settings. This way to
configure the adapter should normally be sufficient.
• Secondly, the RS232 interface can used via its COM port to configure almost all configura-
tion settings. This type of configuration can be only done while in the so-called Terminal
mode.
To reach the Terminal mode, the following steps should be completed:
- Below settings must be specified for a terminal program:
Baudrate: 115.2 kbits/s
Format: 8N1
Flow Control: Hardware flow control must be disabled. This means DTR must be set
inactive (off or low level), and RTS must be set inactive (off or low level).
- Now, the RTS line must be reset to enable the Terminal mode, i.e. the RTS line has to
be activated and deactivated again.
Having enabled the Terminal mode the following commands are available to configure the Au-
dio Codec Adapter.

3 Audio Codec Adapter Setup
3.1 Assembly with DSB75 and AH6-DSB75 Adapter
The Audio Codec Adapter setup with DSB75 and AH6-DSB75 Adapter is based on the refer-
ence environment for development, test and approval purposes that is described in the Startup
User Guide of a specific module. For detailed information on the startup environment please
refer to [4]. The Audio Codec Adapter setup comprises the following hardware components:
DSB75 Development Support Board, AH6-DSB75 Adapter, Evaluation module as well as Au-
dio Codec Adapter. The below Figure 11 shows how these hardware components are assem-
bled - with all jumper settings and switches in their default positions.

3.1.1 Configuration
Depending on the module andthe required audio scenario, the Audio Codec Adapter mayhave
to be configured in different ways - and with different settings. As described in Section 2.1.2.2,
the Audio Codec Adapter can be configured in two ways - by means of a DIP switch or via
RS232 COM port and a special Terminal mode. Both possibilities are referred to in the below
sections that describe the possible configuration settings for various modules, including DIP
switch settings and settings for the module via AT command.
3.1.1.1 Master/Slave
Master and slave configuration settings are seen from the point of view of the Audio Codec
Adapter. For example, if a module is configured as master (see [1]: AT^SAIC), the Audio Codec
Adapter must be configured as slave. In order to avoid outputs driving outputs, this setting is
important. Note that ELS31 modules cannot be configured as masters. As slaves they are
therefore always the receiver of the master clock.
In master mode the bit clock (BCLK; see Section 3.1.1.2) and sampling rate (Framesync =
FSC; see Section 3.1.1.3) are driven by the Audio Codec Adapter. The appropriate level con-
verters are set to output. Also note that with MAX9860, BCLK and FSC can be set separately
as Master or Slave, while NAU8822 can only be switched to either Master or Slave.
3.1.1.2 Bit Clock
In slave mode the bit clock is derived from the PCM/DAI interface lines. There is no need to
adjust anything at the Audio Codec Adapter.
In master mode however, the bit clock is derived directly from the master clock (MCLK) provid-
ed by the Audio Codec Adapter’s MCU.
While in master mode, the following command can be specified in order to configure the bit
clock: BCLK=128 (NAU8822 only) / 256 / 512 / 1024 (MAX9860 only) / 2048 (Default
BCLK rating is 2048MHz)
See Section 2.1.2.2 for details on how to access the Audio Codec Adapter via Terminal mode
for configuration purposes.
3.1.1.3 Framesync
The sampling rate (=Framesync or word select) must be selected for master and slave modes.
The settings can be either 8KHz (NB) or 16KHz (WB) frequency, and either long or short PCM
frame or I2S framesync. The default FSC setting is 8KHz (NB=Narrow Band).
In SLAVE mode the FSC is set automatically once after a reset or by querying the FSC setting
using the command FSC. In this case the FSC frequencies are measured at 8KHz and set to
this value.
See Section 2.1.2.2 for details on how to access the Audio Codec Adapter via Terminal mode
for configuration purposes.

Please note that all PCM data and frame synchronization signals are written to the PCM bus
on the rising clock edge and read on the falling edge, whereas all I2S data and frame synchro-
nization signals are written to the I2S bus on the falling clock edge and read on the rising edge.
The following figures show the various timings for the Framesync modes. For a further mea-
sured sample please also refer to Appendix A - DAI Signal Timings at Oscilloscope.
I2S mode3
PCM short FSYNC mode (NB)
PCM long FSYNC mode (NB)
3. Most modules use I2S left channel only. PHS8 can use the right channel for microphone array function-
ality.

AH6-DSB75 Adapter (X305) must be removed for correct signal directions through the AH6-DSB75 Adapter’s voltage converters. The MS - AGND jumper is show in Figure 11.

ing level switch must be set to “1V8”.
