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.

“TX: RED” and “RX:B/G”: This is LED status indicators.
When R1 controls an external radio, R1 lights up red.
When the external radio receives the signal, R1 blue light or green light.

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).

Switch position-Y, K, C: Direct connection, YAESU, Kenwood, ICOM ... Radio use (6-pin TNC interface)

Switch position-ASL OFF: AllStarLink is disabled, the USB sound card chip stops detecting COS / CTCSS and controlling PTT.

Switch position –ASL ON:  AllStarLink is enabled, USB sound card chip detects COS / CTCSS and controls PTT.
Note2: “ASL ON”, Only use AllStarLink to connect with Raspberry Pi. In other states, the switch position must be in ASL OFF!

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;
USB Audio: USB-Radio Interface,Connect to PC or Raspberry Pi;
USB Detection: USB mouse middle button detection, connect to PC when running ZELLO or YY...;
USB Serial Port: USB serial port, connect to PC when running ECHOLINK / PSK31 / SSTV ...;
About squelch (SQL) control enable, valid or invalid:
YAESU, Kenwood, ICOM radio internal, the value of the SQL signal on the resistance will need to be les 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.

When your radio's squelch connection resistor is 47K or 100K, SQL control is invalid. If you can DIY, you can change the squelch connection resistor to 4.7K, and the SQL is valid after connecting to R1.

Note 3: About YAESU, Kenwood, ICOM car radio whether to support the use of connection, if you do not understand the schematic or need any confirmation, kindly take the pictures of the HD radio schematic sent to me for confirmation

-USB mouse middle key detection chip: the Windows operating system also has the integrated driver; hence, driver installation is not needed. 
-But you need to install the USB serial driver, the download link is as below:

Note 5: Regarding on this R1 appliance box, please be informed that when PC is restarted, it will become abnormal. Please power off/turn off the radio power supply first, then only restart the PC.           
The reason for the above problem is related to the driving control principle of the R1 and PC. There is no solution on this problem yet.          
For the extra info, if the R1 control encounter abnormality after the PC turned off, please set "PC shutdown=USB no power supply" in the PC BIOS.

R1-2020, recommended values:
Minimum 020  Max 111 Default 050
The actual value is confirmed by radio test.

Connection to use in YY: ( YY is only available in Chinese Simplified version)
On the YY channel, select both the microphone input and speaker output to “USB PnP Sound Device” on the system audio management interface, please do not select microphone enhancement or AGC, if you select the option, the audio of other party will be very loud and noisy.
If you want to set the external radio to receive the audio sent through the network from each other, choose to press the mouse to speak: the middle button (selected the green point, and click the middle mouse button).
External radio transmission is the internal default control, it does not need to set. Tip: The middle mouse button control function should be reserved for YY software. In order to avoid mis-forwarding network communications, other software can not overlaps/reuse/override the middle mouse button.
The last two suggestions are to disable the voice prompt function. This is to avoid miss trigger on communication.
