Setup File Reference SDR2-USB Configuration Guide rev 1.0

TimestampTrigger: The TimestampTrigger setup file line specifies a decimal ASCII character that “arms” the time stamping function. Once the trigger character is received, the recorder will insert a time stamp when the next byte of data is received. For example, a trigger value of 10 will configure the SDR2-USB to insert a time stamp after a line feed is received.

TimestampTrigger=gap: Specifying a trigger value of “gap” enables a special time stamping mode where the SDR2-USB will detect time gaps in the stream of incoming serial characters and insert a time stamp after the gap. This is useful for data sources such as GPS receivers that output “bursts” of data periodically.

TimestampFormat (default=MM/DD/YYYY hh:mm:ss\20): Use the TimestampFormat command to provide a template for the timestamps as they are inserted into the file. Timestamp field format values are case- sensitive— month, day, and year fields must be specified in capital letters, while hour, minute, second, and millisecond fields must be provided in lower-case letters. Escape codes are used to insert characters such as spaces, line feeds, carriage returns, and tabs. To include an escape sequence, use a backslash followed by the two-digit hexadecimal ASCII code for the character to use (e.g. \0A for a line feed or \20 for a space).

//enabled time stamping Timestamp=1

//trigger on a line feed TimestampTrigger=10

//include milliseconds and 2-digit year in time/date stamp TimestampFormat=MM/DD/YY hh:mm:ss.ddd\20

DisableIndicators (default=0): Use a setup file line with DisableIndicators=1 to turn front-panel LED indicators off. When enabled, the indicators will flash occasionally in a “heartbeat” pattern. Use this setting to save small amount of power and/or avoid user confusion.
