Unload All
Selecting this option will cause all logged data to be unloaded from the logger.
With the DS-4483 datalogger that has 1MB of storage, this can take a
considerable time even at 9600 bps.
Bit Time Stamping
This option will be used to ensure future compatibility with logging devices and is not available in the
current version of iLink.
Auto-Synchronization
Selecting this option will cause the time on the logger to be automatically synchronized with the time on
the PC after the data has been unloaded.
Unloaded Data Output Format
{Standard date and time, Julian day}
Standard date and time
This option will output each line of data in the following format:
id,dd/mm/yyyy,hh:mm:ss,value(s)
E.g. 100,23/02/2002,18:45:00,1345,1267,1195

value(s)
comma separated value list
values in the specified array
1345, 1267, 1195
The values are saved as stored in the logger and are therefore integers. A
factor may need to be applied to them to convert them back to real engineering
units. Knowledge of the values and their associated sensor sources is required.
A future issue of iLink will link the logger template to the unload routine to enable
automatic conversion of data items. If the unload file is to be imported into
HydroTel 2000™ this conversion is automatically done.
Julian day
This option will output each line of data in the following format:
id,yyyy,jd,hhmm,value(s) E.g. 100,2002,54,1845,13.45,12.67,11.95
