• "TO RADIO" connectors:
"SP" – connect to the radio audio output (speaker or headphone output)
"MIC" – we connect in the microphone input of the radio
"GND" – we connect with the mass of the radio
"PTT" – output for PTT control (open collector)
• Potentiometer
"RX" – adjusting the audio level of the radio
"TX" - adjusting the audio level of the suond card
Recommendations, safety of users:
• Remark! Since the audio signal from the computer should have a minimum level of 0.8Vpp, it is
recommended to set the volume of the speaker on the computer to 100%
• we recommend using cheap external USB sound cards. In older computers, laptopswith built-in internal sound
cards can cause unstable system performance
• read the radio manual carefully before connecting to the interface. In some cases, the PTT connection may
require a resistor
• the interface requires appropriate cables to connect to the radio and sound card. These cables must be made by
yourself
• How to connect the Baofeng UV-5R radio to the DIGIVOX-2 interface can be found on the last page of the
instruction
