account, which causes an error in the synchronization of at least
several seconds.
2) Establish a Bluetooth link with the DTI-2 and start up the
DTI-2_BT_StreamingDataViewer program that can be found on the
internal data storage of the DTI-2. After opening the communication
in this program synchronization will take place automatically.
Battery charging
Battery recharging is done with the supplied USB charger via the USB
cable, which needs to be inserted into the USB connector that can be
found behind the fastening hinge. A red LED placed close to the USB
connector indicates active charging. It takes about 2 hours to charge the
device from empty to full. The red LED may not switch off when a full
charge state is realized. The sure way to check whether the battery has a
full charge is to unplug the USB cable, and to plug it in again: when the
red LED stays out the battery is fully charged.
Data Readout
1) Connect it to a Windows7
/Vista/XP™ PC with the USB cable. A blue
LED close to the USB connector indicates a functional USB
connection.
2) The device mounts as
‘’Device with Removable Storage’’ on your PC.
Open the explorer and click the drive associated with the DTI-2
(should this fail to happen unplug the USB cable and reconnect it).
When asked to scan and fix the device, please comply, and tick both
check disk options. After the scan the DTI-2 drive mounts normally.
3) Copy the data files to a location of your choice on your own computer.
4) Undock the device after this operation
Data format and data visualization
The measured data is stored in a binary file named DTISamples0XXX.dti,
where XXX is the serial number of the device. This file can be converted
into a text file with the DTI-2_SampleFileParser-P program which is
present on the DTI-2 data storage disk. Run this program, select the .dti
file, and choose Convert DTI Sample File. This will generate a text file
with all data in lines with this format:
yyyymmddHHMMSSmmm|NNNN|ev|ttttt|sksks|xxxxx|yyyyy|zzzzz|vb|etete|eieie|rrrrr
A minus sign may precede the accelerometer data xxxxx, yyyyy or zzzzz. The
description of the line coding is given in the next Table.
