AT Command Set

8.24 AT^SNFO Set audio output (= loudspeaker path) parameter

Test command

AT^SNFO=?

Read command

AT^SNFO?

Write command

AT^SNFO=<out- BbcGain>,<outCali- brate[0]>,...<outCali brate[4]>,<out- Step>,<sideTone>

Response

^SNFO: (list of supported <outBbc Gain>), (list of supported <outCali- brate[0...4] >), (list of supported <outStep>), (list of supported <sideTone>s)

OK

Parameter

See write command

Response

^SNFO: <outBbcGain>, <outCalibrate[0]>,...<outCalibrate[4]>, <outStep>, <sideTone>

OK

Parameter

See write command

Set TA's loudspeaker path parameters.

Response

<outBbcGain> <outCalibrate[0]>...<outCalibrate[4]> <(outStep)> <sideTone>

OK

Parameters

<outBbcGain> Setting for DAC gain amplifier attenuation 0 – 3 (0=0 dB, 3=-18 dB, 4 steps of 6 dB)

<outCalibrate[0]> ... <outCalibrate[4]>

 

Multiplication factor 0 – 32767 for output samples

 

Attenuation = 20 * log (outCalibrate[n]/32767)

<outStep>

Setting of actual volume; 0 – 4, i.e. outCalibrate[n]

<sideTone>

Multiplication factor 0 – 32767 determining how much of

 

the original microphone signal is added to the earpiece

 

signal.

 

Side Tone Gain/dB = 20 * log (sideTone/32767)

Reference

Siemens

Note

•Write command works only in audio modes 2 to 6!

•Read and write options of this command refer to the active audio mode.

•The values <outStep> can be changed also by ^SNFV.

•The range of <outCalibrate> is up to 65535 but will be suppressed to 32767. A value above <outCalibrate> = 65535 will cause a error

•Changed values will not be stored automatically, but via the AT command AT^SNFW except <outStep>. The parameter <outStep> will be saved after AT^SMSO only.

•The volume level as well as mute affects all audio modes.

•In case of audio mode 1 the parameter <outStep> has no effect.

•CAUTION! When you adjust audio parameters avoid exceeding the maxi- mum allowed level. Bear in mind that exposure to excessive levels of noise can cause physical damage to users!

MC35 specifications

The Siemens MC35 is a compact and versatile modem designed primarily for mobile communication, data transmission, and machine-to-machine (M2M) applications. Launched in the early 2000s, it quickly became popular due to its blend of performance, reliability, and ease of integration, making it a solid choice for developers and businesses.

One of the key features of the MC35 is its support for GSM and GPRS technologies. This allows it to connect seamlessly to various networks, enabling users to transmit data at speeds that were impressive for its time. The GPRS capability can offer data rates of up to 171.2 kbps, allowing for efficient data transfer even in areas with limited connectivity.

The MC35 is designed to support both SMS and voice functionalities, making it adaptable for a range of applications. This includes remote monitoring, telemetry, and alarm signaling. The ability to send and receive SMS messages is a significant advantage for applications that require immediate alerts and notifications, enhancing its utility in security systems and industrial automation.

Furthermore, the modem is equipped with a range of interfaces, including serial communication (RS232), which makes it compatible with various hardware devices. This facilitates easy integration into existing systems, whether for industrial machinery or consumer electronics. Additionally, it features a robust software development kit (SDK), which enables developers to create custom applications tailored to their specific requirements.

Power consumption is another notable characteristic of the Siemens MC35. It is engineered to be energy-efficient, which is especially important for battery-operated devices or systems that require a prolonged operation without frequent recharging or maintenance.

In terms of physical characteristics, the MC35 is compact and lightweight, allowing it to fit into various enclosure designs without occupying much space. Its durability ensures it can perform reliably in different environments, making it suitable for outdoor and industrial applications.

To summarize, the Siemens MC35 stands out as a reliable modem with a rich feature set that includes GSM and GPRS support, SMS and voice capabilities, easy integration through various interface options, and energy-efficient operation. Its adaptability makes it a valuable tool for a wide array of communication and data transmission tasks, solidifying its place in the evolution of mobile communications technology.
