DT80 Range Downloading Data
From dataTaker Wiki (FAQ)
Can I choose how much memory to download?
Yes, it is possible to download individual schedules only, or time to time periods of all or any individual schedule. In addition time to end, or beginning to time.
Can I download while the logger is logging?
Yes, downloading or transfer of data from the DT80 range loggers via a host port, FTP or USB flash drive doesn’t stop data logging, but may limit the speed of faster schedules (1 second or faster) and will effect return of data to a PC in real time.
Can I download by time?
Yes, time to time, or start of file to time, or time to end of file. All schedules or by individual schedule.
How long does it take to download a 1MB data file?
Using default settings and a 1MB data store file, standard UNLOAD time is;
- USB: approximately 3 minutes.
- RS232: approximately 5 minutes (@57600 baud).
- ETHERNET: approximately 3 Minutes.
Transfer of binary files using FTP is much faster than standard unload. The standard UNLOAD command unloads ASCII data (in a CSV format).
Replay files are also CSV files but include additional information.
What is the fastest way to unload my data logger?
Using FTP (File Transfer Protocol) over Ethernet.
A 1 MB data store file will be transferred in less than 10 seconds. Assuming typical LAN performance.
Transferred file is in binary format and requires a utility such as DeView to view or export the data.
Can I use a iPhone or iPad?
Yes, There is an app called DT-Remote from Pacific Data Systems that allows you to view data on your iPad or iPhone. DT-Remote is also available for Android systems
Further details are available from Pacific Data Systems
Can I download data using a USB Flash Disk?
Yes, the CopyD command can be used to either copy or move the binary data files from the internal disk to the USB memory stick.
A utility such as DPlot is required to view or export the data from the binary file.
How fast is downloading to the USB flash disk?
This will vary due to performance variations with the USB flash disks, as well as be affected by the size of the files and how much data is actually stored.
For a 1MB file the approximate transfer time will be 20-30 seconds.
Actual transfer time will also be effected by other logger activity.
Using CopyD Format=DBD command to create a binary file on the USB flash disk.
Does not include time to read and recognize the flash disk on insert.
Can I get my data over the internet?
Yes, Either using direct connections within dEX or DeTransfer or with FTP using a browser or FTP client the binary data store files can be copied from the DT80 range logger.
Internet access requires the DT80 range logger to be assigned a visible IP address. You may need to place it outside a firewall to be visible.
A utility such as DPlot is required to view or export the data from the binary file.
Can I FTP data files?
Yes, data store files can be moved using FTP via Ethernet or RS232/PPP.
The DT80 range products are capable of both FTP Server and FTP Client (from version 6.10) operation.
FTP Server: Allows FTP folders to be accessed from IE and other browsers. Must be remote request from FTP Client. Supports anonymous login – read only.
FTP Client: As of version 6.10 the DT80 range loggers can also send data to a remote FTP server using the Unload, COPYDATA, MOVEDATA and ARCHIVE commands. See the latest user's manual for more details. This is sometimes termed 'FTP Push' as the logger initiates the data file transfer. See these examples for methods of automatically transferring data files.
With version 8 firmware the COPYDATA and ARCHIVE commands have been replaced by the COPYD command. The COPYD command can be passed multiple parameters that allow unloading of data to FTP sites, different data formats, saving data to internal or USB memory devices. Please refer to the DT80 range User manual for more details
Can I email data files?
Yes. Version 9.08 firmware adds the ability of being able to email the data as an attachment.
Can I read my data using Notepad or Excel?
Standard UNLOAD and REPLAY files are text files using a CSV format, these can be viewed using texteditors or spreadsheets.
Binary data store files need a utility like DeView to view or export the data to a CSV format.
Normal unload generates CSV text based files in either .csv or .dlr (REPLAY) file types. Binary files are those found on the USB flash disk or transferred using FTP.
How do I convert binary data files (.dbd) to CSV format?
The simplest way is to use DeView to open binary data files and then save them to CSV format.
Another option is to use the dump_dbd command line utility that is available from our downloads page. To use this utility you can issue a command such as:
dump_dbd -d data.dbd > data.csv
- "-d" means output only data (no header information is output).
- "data.dbd" is the file to convert.
- "> data.csv" means send the output of the command to the nominated file (in this case data.csv).
This utility can also be loaded onto a USB drive and configured so that data files can be automatically converted to CSV and displayed in applications such as MS Excel.
