Hardware interface descriptionSIP2402VFor the network audio module, all external connections use terminals, the powersupply uses 2.0mm terminals, the network uses standard RJ45 connectors, and the others are1.25mm connectors.port type definitionP — — — power supplyAI — — — Analog input (in this case, audio input)

In most cases, the digital input and output terminals are connected to the outside, andan external drive circuit is required to protect the processor from damage. Analog input/analogoutput also need to increase the amplifier circuit and input protection circuit.1. Power input port
The network audio module adopts DC power supply mode, wide voltage input, power supplyrange DC12 ~ 24V. Because it involves audio and a processor up to 400MHz, the input powersupply voltage must be as stable as possible, and the minimum current is guaranteed to be500mA.Interface description:definition type describe1 VDD P Power input, the voltage is DC 12-24V2 GND P power ground2.

If a stereo signal such as MP3 is played, a stereo output will be provided; if the audio sourcefrom the network is detected to be a mono audio format such as mono ADPCM/PCM, the left andright channels will output the same signal.As an audio output indicator, P-ST can control the enable terminal of the digital poweramplifier to ensure that the speaker has no noise when there is no sound output, and saveenergy consumption at the same time. P-ST can also be used as the control terminal of a relay tocontrol the power supply of the power amplifier circuit of the rear stage.The change of the P-ST signal is determined by whether there is an audio stream in thenetwork, regardless of the assignment of the output audio signal. At the same time, the P-ST willreturn to low level when no audio signal is received for more than 1 second. Sometimes, we wantP-ST to become high level without sound output, can play audio stream without sound.3. Amplifier output port
SIP2402V has 215W power amplifier output, and can also be changed to 140W poweramplifier output by adjusting the circuitInterface description:definition type describe1 R+ AO Power output of the right channel, connected to the positivepole of the passive speaker2 R- AO Right channel power output, connect passive speakernegative pole3 L- AO Left channel power output, connect passive speakernegative pole4 L+ AO Left channel power output, connect to positive pole of

When the module needs external input (such as CD player, mixer) for local soundamplification, connect On to 3.3V high level to make the power amplifier chip enter the start-upplayback state. Even when the module is idle and standby, local sound amplification can also beperformed.

5. Network InterfaceThe network interface adopts two connection methods:1) Adopt RJ45 standard 10/100M adaptive network interface. There are two indications on theRJ45 socket, one for connection and one for data sending and receiving.2) With the tail wire method, most of the camera tail wires can be used directly. In this way, thenetwork audio module can be placed inside the device.Interface description:definition type describe1 V P Power input, the voltage is DC 12 ~ 2V2 G P power ground3 1 N Network cable 1

Among them, 7 cores (or 9cores) are connected to this terminal, and the other two cores are connected to the power
terminal.Among them, 1, 2, 3, and 6 can be exchanged with each other, as long as 1, 2 or 3, 6 arepaired. 8 and 9 can also be interchanged.6. POE powered (PD) interfaceThrough this interface, an external POE power receiving module can be connected toachieve the function of network power supply. After the POE power receiving module is installed,DC power supply can also be used.Notice: The POE power receiving module outputs 12V voltage, which is connected tothe power input of the module. If a DC external power supply is used at thesame time, unpredictable conditions may result.

7. Application scenariosSIP2402V network audio module can be used with very few peripherals. For example, it can beintegrated into active speakers as IP network speakers, integrated into traditional constant-voltagepower amplifiers as network constant-voltage power amplifiers; it can also be integrated into industrialrobots for added playback and other functions.1. Broadcast applicationNetwork audio equipment can accept audio streams from the network and convert them intoanalog audio signals for output after decoding. The figure below is a standard playback applicationscenario.SIP2402V network audio module is used as a playback terminal, and only needs to increase the
power supply and external power amplifier. It can be used as a single device, or integrated in otheraudio devices (power amplifier, or active speakers, etc.), making it a network audio playback terminal.The broadcast host can use our company''s broadcast system control software, broadcasting
equipment, network microphone, etc., or the user can develop his own broadcast software based onour company''s DLL dynamic library. Both the playback software and the playback development kituse our company''s private protocol, and only support the playback of our company''s equipmentmodules. As a playback terminal, the network audio module uses our proprietary protocol for playbackcontrol, and can only be used in a LAN or VPN intranet. In fact, customers can also choose todevelop their own playback software of SIP protocol, which can be used in LAN or Internet.LAN/WANLAN/Internet PlaybackterminalBroadcasthosts Playbackterminal
