Overview
CentrePoint Data Hub
The CentrePoint (CP) Data Hub from ActiGraph is a home-based communication gateway capable of transmitting both one-minute
epoch level and raw data captured by ActiGraph GT9X Link activity monitors to the CentrePoint cloud software platform via 3G cellular
network. The CP Data Hub also functions as a charging hub for ActiGraph Link activity monitors. This User Manual contains instructions
on how to set up, operate, and manage your CentrePoint Data Hub.

Pair the CP Data Hub with the ActiGraph Link
Follow the instructions in the CentrePoint User Manual or your custom Site Manual to assign the ActiGraph
Link activity monitor to a new subject in CentrePoint. After the assignment is complete, remove the Link from
the dock (connected to your PC).
Connect the adapter end of the power cable into the back of the CP Data Hub and plug the other end into a
wall outlet, using the international adapter if necessary.
The blue LED status light on the back of the CP Data Hub will flash during startup. It may take up to 20
seconds for the LED to begin to flash. Once the CP Data Hub connects to the cellular network, the blue LED
will stay on solid.
Connect the Link dock to the USB port on the CP Data Hub using the USB cable.
Insert the Link into the dock connected to the CP Data Hub. Once connected, a progress wheel will appear
on the Link screen indicating that data upload has begun. A checkmark will appear on the Link screen when
this is complete.

Operating the CentrePoint Data Hub
Setting up the CP Data Hub in the home (instructions for subjects)
The CP Data Hub should be placed in a location where the subject spends a lot of time.
Connect the adapter end of the power cable into the back of the CP Data Hub and plug the other end into a
standard wall outlet, using the international adapter if necessary.
The blue LED status light on the back of the CP Data Hub will flash during startup. It may take up to 20 seconds
for the LED to begin to flash. Once the CP Data Hub connects to the cellular network, the blue LED will stay
on solid.
If the CP Data Hub cannot connect to the cellular network (or if it loses connection), the blue LED will continue
to flash. If this continues for more than two minutes or occurs throughout the day, move the CP Data Hub
to a new location.
Once the CP Data Hub is successfully connected, plug the Link dock into the USB port on the side of the CP
Data Hub.

2Wireless uploads (Bluetooth®)
If the CP Data Hub has been configured for wireless Bluetooth® uploads, it will periodically attempt to connect to
the ActiGraph Link wirelessly when the activity monitor is within range, which is approximately 30 meters. Once
connected, the CP Data Hub will download one-minute epoch summary data from the ActiGraph Link.
If a full day’s worth of data is downloaded, it will be immediately transferred to the CentrePoint system via 3G
cellular network.
If only a partial day is downloaded via Bluetooth®, the CP Data Hub will store that data until a full day is queued.
The data will then be uploaded to CentrePoint.
Note: CentrePoint Data Hub default settings require a full day of data before an upload is initiated, however this can be
congured for each study.

Raw data uploads (USB)
The CP Data Hub can be used to upload raw actigraphy data using the Link dock.
Insert the ActiGraph Link into the connected dock with the logo facing up. A progress wheel will appear on
the ActiGraph Link screen once the upload begins.
When the upload is complete, a checkmark will appear on the screen. This can take several minutes to several
hours, depending on how much data is on the device.The ActiGraph Link can now be removed from the dock.
Summary one-minute epoch data and the raw data file (if applicable) are immediately available in CentrePoint.
See "Viewing uploaded data" section below.
4Charging the activity monitor
The CP Data Hub charges the ActiGraph Link battery anytime it is placed in the connected dock.
During charging, an animated battery icon will appear on the ActiGraph Link screen and the charging dock
will display a yellow LED.
Charging is complete when the LED turns green.
If the dock displays a red LED, this indicates a charging problem. Remove and reinsert the activity monitor in
the dock.
It takes approximately 2-3 hours to charge a fully depleted battery.
