Trimble R7 GPS Receiver Operation
Note – When you connect to a receiver in the Data Transfer utility, you
must use a GPS Receiver (R/5000 Series) device definition. If you use a GPS
Receiver (4000 Series) device definition, the Data Transfer utility will be
unable to establish communication with the receiver.
When transfer is complete, the Data Transfer utility automatically
converts the file to the DAT format. If you are using Data Transfer from
within the Trimble Geomatics Office software, the Check-in dialog
appears. For more information, refer to the Trimble Geomatics Office
User Guide.
Note – A file in DAT format is approximately six times the size of the
corresponding file in the Trimble R7 receiver internal format. Before
transferring files, make sure that there is enough space on your computer.
6.3 Transferring Files Directly from a
CompactFlash Card
In a Trimble R7 receiver, all data is stored on an internal CompactFlash
card. There are two ways to transfer files between the receiver and the
office computer:
• Connect the receiver to the office computer and use the Data
Transfer utility to transfer files.
• Remove the CompactFlash card from the receiver and connect it
directly to your office computer, where it functions like a normal
disk drive. Use Windows Explorer to transfer files.
When you use the Data Transfer utility to transfer data files from the
CompactFlash card while it is still inserted in the receiver, the Data
Transfer utility converts the raw receiver data (.T01) files you select into
the Trimble DAT file format.
However, if you connect the CompactFlash card to your computer and
then copy or move files to your computer, it treats the card like any
other disk drive, and transfers the files without converting them. You
need to convert these raw receiver files to DAT format files before you
can use them on your office computer.
