Description

For Echolink & Zello YY Voice Interface Board Controller Radio-Network USB Sound Card Version   

Features:

1. Built-in USB sound card chip, with high-quality audio input and output.

2. Built-in USB serial chip. E.g. launch control using RTS, receive control using DSR. (ECHOLINK User)

3. The built-in audio detection chip controls the radio's PTT button and outputs the sound to the speakers by the radio-compute-controller. （ZELLO User）

4. The control-software forwards the input-voice of the microphone with the detection of the SQL radio signal from the USB chip（ZELLO User）

5. The USB-Radio Interface is compatible for AllstarLink. GPIO Detect COS and CTCSS input . GPIO outputs and control the PTT (ASL soundcard function).

6. The user’s computer will not get Power/RF interference noise from the power supply from radio because the R1 has the optocouplers and the isolating transformer.

7. R1 introduce the of electric conductor or circuit (inductance) to isolate Power/RF interference and high-frequency radiation.

8. Full Metal case, shields all other interference.

9.Industrial design with standard production process.

10. LED status indicators.

Control Principle:

In general, the Internet voice chat software, with the help of output audio controller that detects audio input from the radio PTT, hence the audio will transmit over. On the other end, once radio receive the audio, the controller detects the SQL signal through the USB control network, the voice chat software will forward to the audio to the radio. In this way, it will be on the radio-linked network.  

Controller Applications:

By getting the radio link to the network, you can set up radio links or relay links and extend the range radio transceiver or repeater, therefor global radio link is achieved.

Supported Software:

AllstarLink, ECHOLINK, ZELLO, SSTV, psk31, SKYPE, QT, YY and other chat intercom and data transfer software.

Notes: There are some software that not support on USB and control detection, thus at this time, while on the computer microphone input, we can use the software VOX function, or use the keyboard conversion software to trigger them.
