interval” is settable, and specifies how long the Drive By Download data manager waits after a
download before attempting a new download. The more often the data is downloaded, the
quicker the download process occurs.
Foreground/Background Download
SpreadSmart Rx
TM
can be configured to allow download in the foreground (operator gets a
warning the download is underway and cannot spread during downloading) or background
(operator gets no warning that downloading is underway). Default is “foreground downloading.”
Download Time
The time it takes for data to be transferred from the
SpreadSmart Rx
TM
to the base station
computer is a function of the amount of data stored on
SpreadSmart Rx
TM
SD card
.
The amount
of data stored between downloads is dependent on the “log interval” set on your
SpreadSmart Rx
TM
and the amount of spreading that occurs. Each site will want to adjust its “log
interval” in the system set up to collect data at the optimum frequency that balances download
speed and data volume.
Log interval
SpreadSmart Rx
TM
is continuously recording data in RAM, but writes that data to the SD card as
often as the “log interval” determines. A 60 second interval is recommended. Longer log
intervals result in data being stored less often and transfer speed increasing, shorter intervals
result in data being stored more often and slower transfer speeds.
The
SpreadSmart Rx
TM
has storage capacity for 32 megabytes of data (approximately 7 days x
24 hours of continuous spreading) before the SD card fills. We recommend that data be
downloaded every time a truck returns to the base station for supplies or at the end of the shift.
For this reason, the base station PC should be located at the site where the trucks return with the
most regularity.
Data Linkage Range:
Linkage range is no more than 250 feet with a clear line of site between the truck transmitter
antenna and the wireless access point antenna at the base station. Linkage range may be larger,
but must be verified at the site.
Using the DBD 3.x and DAT software
The software is designed to operate automatically on your PC desktop.
Initial Setup: choose the preferences under the edit menu. Set the data path to direct your
downloaded files to the location you choose on your PC. Once this data path is set, it should not
be altered since the
DBD 3
uses this data path when creating reports. Changing the data path can
result in reports being created from partial data.
Set the frequency that the software uses to look for trucks from which to download data. Factory
presets are recommended. Choose the vehicle list and add truck ID for the truck(s) from which
you choose to download data.
Normal operation: open the file by double clicking on the DRIVEBY icon on your desktop.
Leave the file open to operate automatically. You can minimize it if you wish.
Note: do not
close the software during a download or the downloading will terminate without
completing. It can however, be re-started at the beginning without loss of data.
