SINREY SIP2403V digital broadcasting and two-way intercom PCB board

SIP2403V network audio module is a general independent SIP audio function module, which can be easily embedded into OEM products.The module encodes and decodes SIP protocol and RTP audio stream from the network.

The module supports a variety of network protocols and audio codec protocols, and can be used for VoIP and IP paging, high-qualitymusic streaming media playback and other applications。

SIP2403V also provides two serial ports and eight digital I / O, allowing the user to program control.

This series of modules can be applied in the following fields:
• Various commercial network audio streaming applications
• Network alarm, network player
• Universal two-way full-duplex VoIP intercom for paging and intercom applications
• Source Encoder for IP Audio Distribution Applications
• Background Music and Music On Hold Encoder for VoIP Applications
• Compatible with various low-latency IP audio encoders
• Unmanned parking lot, self-service charging station intercom terminal
• Expressway tunnel intercom, toll station intercom terminal

Functions and Features
How audio works:
Audio decoding:That is, audio playback. Receive the audio stream from the network, and output high-quality audio signal through the line after decoding by the module. Currently supports the following audio formats:MP3.WAV (PCM +IMA ADPCM), G.711, G.722, etc., can play audio streams with a maximum sampling rate of 48k and 320kps.
Receive the audio stream sent by TCP, UDP, RTP, multicast, broadcast, etc. in the network, and play it after local decoding.
Audio encoding: Support G.711a/u, G.722 and RTP multicast mode.
control method:
Button control:Directly through the IO port on the module, control the module SIP intercom or initiate RTP multicast
Serial port control:Through the control serial port on the module, control the module SIP intercom or initiate RTP multicast
Network Control:Through network commands on other devices in the network, control the control module SIP intercom or initiate RTP multicast
System status output:
Audio input (M-ST), output status (P-ST): You can connect indicator lights or control relays.
Amplifier output:
With 2*15W power amplifier output, it can also be changed to 1*40W power amplifier output by adjusting the circuit
With 1 channel local audio input to realize the local sound amplification output function
Extended functions (the following functions are not supported by all models):
POE power supply:Provide POE power receiving module interface
General I/O: Control extended circuits or devices
Universal serial port: Control extended circuits or devices
Real Time Clock: The module is powered off, or the time is not adjusted by the server to provide accurate time, which can be obtained through the serial port or network, or the audio file can be played regularly
