R1-2020 ASL-Echolink-zello-YY Voice Interface Board USB Sound Card Version SSTV PSK31 AllStar Link Controllerb for FAESU Motorola Icom KENWOOD

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 indictors.

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.

Support Softwares:
AllstarLink,ECHOLINK, ZELLO, SSTV, psk31, SKYPE, QT, YY and other chat intercom and data transfer software.
Notes: There are some softwares are 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.

Product Description:
1. "TX: RED" and "RX:B/G": This is LED status indictors.
When R1 controls an external radio, R1 lights up red.
When the external radio receives the signal, R1 blue light or green light.
2. Switch position-MOTO:
Connect 6-pin to 16-pin converter board, used by Motorola radio stations(16-pin interface),(Default accessories)
Connect 6-pin to 26-pin converter board, used by Motorola radio stations(26-pin interface),(Optional accessories)
3. Switch position -Y, K, C:
Direct connection, YAESU,Kenwood, ICOM ... Radio use (6-pin TNC interface)
4. Switch position-ASL OFF:
AllStarLink is disabled, the USB sound card chip stops detecting COS / CTCSS and controlling PTT.
5. Switch position –ASL ON:
AllStarLink is enabled, USB sound card chip detects COS / CTCSS and controls PTT.
Note: "ASL ON", Only use AllStarLink to connect with Raspberry Pi. In other states, the switch position must be in ASL OFF !!!
6. DIN 6 Interface:
Use 6-pin Cable.R1 to connect YAESU / Kenwood / ICOM-radio;
Use 6-pin cable and "6-pin-16 pin conversion board". R1 connect Motorola-radio;
Use 6-pin cable and "6-pin-26 pin conversion board". R1 connect MotoTRBO-radio;
7. USB Audio:
USB-Radio Interface, Connect to PC or Raspberry Pi;
8. USB Detection:
USB mouse middle button detection, connect to PC when running ZELLO or YY...;
9. USB Serial Port:
USB serial port, connect to PC when running ECHOLINK / PSK31 / SSTV ...;
10. About squelch (SQL) control enable, valid or invalid:
YAESU, Kenwood, ICOM radio internal, the value of the SQL signal on the resistance will be less than 10K (max 10K), then the test will pass. If the SQL signal on the resistance value is greater than 10K (<10K) , then it will not support.
The use of the following schematic is for YAESU FT-7800, the SQL on the resistance number R1202 is 4.7K, which is supported by R1.

Package:
Host * 1
USB cable *2
6-pin data line *1
6-pin, 16-pin conversion board X1 (available by default, optional "6-pin, 26-pin conversion board ")

NOTE:
if the relay is connected with YY interface board, the relay shall turn off the delay function. Otherwise in just connect when missing a word. Repeated echoes may also occur. This is because the voice control PTT principle determines that the relay cannot be delayed. It is not the defect of my interface board.
