4.2.2 River Height Record
The following data represents the historical river height record as output from an RRDL-3 data
logger. The example below represents a data record as presented to a computer after invoking an
ASCII DUMP command. A HEX DUMP format (memory image) is also available where rapid
dumping is essential. A convert program running from a PC environment will then reconstruct the
record to its ASCII format. Each parameter is separated by a ‘space’ character with each line
terminating with a carriage return line feed marker, (< crlf >). Additional housekeeping events,
identified as ‘plain English’ text fields, are automatically logged to the record on the instance of a
variety of events. The text fields, Record Clear, Logging Disabled, Logging Enabled and Record
End are examples of some of the text event indicators. NOTE: In the combined rainfall and river
mode of operation, the logger does not generate the Connect and Disconnect messages.
