3. Operations
3.1 Setup file reading
The setup.txt file on the USB storage device is read only when power is applied to the SDR2-USB. Once read, all settings found in setup.txt are retained by the recorder.
3.2 Record mode operation
When you press the record button, the SDR2-USB searches for the current file specified in the setup file, creates it if necessary, and opens it. Once the SDR2-USB has successfully opened the file, the record indicator turns on and the SDR2-USB enters record mode. Once in record mode, the SDR2- USB records any data received on the data port to the open file.
3.2.1Receiving data
The data indicator flashes when the SDR2-USB receives data. This indicator is useful to ensure that the SDR2-USB is actually receiving data via the data port. Note: this flashing indicator does not guarantee a correct baud rate.
Incorrect baud rates between the data source and SDR2-USB may still cause the data indicator to flash and invalid data to be written to the current file.
