Getting Started in the Lab
•
Connect the DATA-CUBE³ via the light grey USB cable with a computer. The DATA-CUBE³ will appear
as a USB storage device and the configuration file can be accessed. If desired edit the configuration
file and change the values like sampling rate, gain, number of channels, interval of active GPS accord-
ing to your requirements. A brief description can be found in the configuration file itself. Please refer to
the configuration file manual for a detailed description.
•
Safely remove the USB storage from your Windows computer or unmount the drive in Linux before
disconnecting the USB cable.
•
Insert the batteries with correct polarity (DATA-CUBE³ Type 1) or connect an external power supply
(DATA-CUBE³ Type 1 or 2).
•
Wait typically 3-5 minutes for reception of the GPS signal at an open sky location. When only the red
and blue LEDs are blinking at 1 sec interval the DATA-CUBE³ is operating ok. After the DATA-CUBE³
has received a GPS lock once, it can acquire data without GPS signal as well (e.g. for installations
inside tunnels or buildings). Only red LED is blinking when the GPS signal is lost.
Important notice:
It is mandatory that the DATA-CUBE³ receives a GPS signal after the deploy-
ment at least once before being switched off. This allows a proper resampling in the post-pro-
cessing.

Field Installation
DATA-CUBE³ Type 1
•
Insert the batteries into the battery compartment and check for correct polarity!
•
Connect the sensor with the upper left socket (10-way) for data recording.
•
Wait typically 3-5 minutes for reception of the GPS signal at an open sky location if the coordinates in
the configuration file match your location by a radius of about 300km. It might take much longer if for
example the coordinates do not match the values in the configuration file. Adopting the correct GPS
coordinates in the configuration file will speed up the GPS synchronization drastically.
•
The DATA-CUBE³ is OK & recording when the red and the blue LEDs are blinking at 1 sec interval.
•
Optionally: To check the function of the DATA-CUBE³ and to see the current noise you can connect
the black 7-way cable to the upper right socket and connect it to a laptop. The DATA-CUBE³ type 1
must be powered by internal batteries during this check. The software CubeMonitor will show the live
recorded data.
•
If the correct operation of the DATA-CUBE³ has been verified, it should be wrapped into a plastic bag
and dug into a shallow hole. Make sure that the top side is uncovered! Otherwise the built-in GPS
antenna will not receive a signal.
DATA-CUBE³ Type 2
•
Connect the external power supply with the DATA-CUBE³ using the 4-way socket.
•
Connect the external GPS antenna using the BNC socket and place it outside if the DATA-CUBE³ will
be installed in a shelter, vault or building.
•
Connect the sensor with the upper left socket (10-way) for data recording.
