SDR2-USB Configuration Guide rev 1.0 Operations 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. -
Page 18: Stopping Recording
Operations SDR2-USB Configuration Guide rev 1.0 3.2.2 Stopping recording Incoming data is written to the open file as it is received until you stop recording by pressing the record button. The SDR2-USB then closes the file, updates its directory entry (recording file size, date, and time), and returns to stop mode. -

Operations SDR2-USB Configuration Guide rev 1.0 3.3 Lithium battery maintenance The SDR2-USB's real-time clock uses a small lithium battery to maintain time when external power is unavailable. The life of this battery should exceed 5 years. If you find your SDR2-USB is not keeping time correctly when power is lost, you may need to replace the battery. -

SDR2-USB Configuration Guide rev 1.0 Serial Port Basics To transfer data asynchronously, the UART frames the 8 data bits between a stop bit and a start bit. The start bit is always a zero, while the stop bit is always a one. So, a byte of data sent serially is made up of 10 bits instead of the usual 8. -

Most devices have female connectors (DB9 or DB25) if they are configured for DCE operation and male connectors if they are configured for DTE operation, but this is not always the case. - Page 37 SDR2-USB Configuration Guide rev 1.0 Serial Port Basics CTS, etc.), RS-232 devices use +3V to +25V to assert the signal and –3V to –25V to deassert the signal. These voltage levels are defined in the EIA/TIA- 232E specification. So, when a DTE devices drives RTS at –9.50V, it is signaling the DCE to stop sending data.
