Store cables always use the straight TRRS connector on the Digirig side. Serial port can also be used for firmware, presets or channels programming. ![]() Serial socket is used for optional CAT control with the transceivers supporting this functionality. All transceivers will use this connection for digital modes. These are the minimum required signals for the digital modes. Audio socket connects ground, audio input, audio output and hardware PTT line. On the transceiver side Digirig has 3.5mm TRRS sockets labeled “audio” and “serial”. In Windows 11 edit system’s privacy settings to allow applications access to Digirig’s recording device (Microphone). Inside the level tabs set initial values at 20-50% and disable any custom features (AGC, Spatial sound etc.).Īudio level adjustments are covered in more details in this post. You can also change the default icon to modem. Inspect the properties of Digirig’s playback and recording devices renaming them to “Digirig” so they can later be easily recognized in the lists inside of the digital modes apps. This designation should be moved from Digirig back to the computer’s regular microphone and speakers so the unrelated audio doesn’t end up on the air. Windows assigns recently added sound card as a Default Device and Default Communication Device. They will be listed as “USB PnP Sound Device”. Open Control Panel or equivalent utility to locate playback and recording components of the Digirig’s sound card. You will need it later.Ī driver installation may be required for the serial port device. The devices will be found under “Sound, video and game controllers” and “Ports (COM & LPT)” with names “USB PnP Sound Device” and “Silicon Labs CP210x USB to UART Bridge (COMx)” respectively. Using the Device Manager or equivalent utility in the OS of your choosing, confirm that the system has detected Digirig’s sound card and the serial port bridge. Detecting Componentsīefore connecting your Digirig with the transceiver, first connect it to the computer. ![]() Typically it’s a USB-A connector or in case of newer computers, tablets or phones it can be a type C connector.ĭigirig can be connected to any USB host device such as Windows computers, MacOS computers, Linux machines including Raspberry Pi boards as well as Android devices. On the other end of the cable there can be any standard USB connector matching the computer’s socket. This connection is used for both communication and for powering the device. Computer Connectionĭigirig is connected to the computer with a single cable plugged into the Type-C socket labeled “USB”. For a complete technical overview including the configuration options and schematic, please refer to this post. There is also the circuitry for hardware PTT switching, serial port level conversion, filtering and signal attenuation. Inside your Digirig there is a USB hub with two downlink devices: a sound card based on a popular CM108 chip and a serial port bridge based on CP2102 chip. If at any point in the process your results differ from what is described here, please refer to the Troubleshooting Guide for possible remedies. Regardless, if you are a first time owner of a Digirig unit – this post is for you. ![]() Maybe you spend all day trying every possible option before reluctantly opening the documentation. Maybe you read the manuals cover-to-cover including safety warnings and legal disclosures before you power up the new gizmo.
