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.

Getting Started
Your CP Data Hub package contains the items listed below. A CentrePoint user account and ActiGraph Link activity monitor are required
to use the CentrePoint Data Hub and must be purchased separately.
You will also need:
CentrePoint Data Hub Power Cable
USB Cable
ActiGraph Link and Accessories (Not Included)
Link Dock
CentrePoint Account (Not Included)

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
congured for each study.

The CP Data Hub performs wireless uploads of summary data using Bluetooth®, and raw data is uploaded via USB
connection. Please reference this Helpdesk article for more information about the difference between raw and
summary data.

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.

Technical Details
The CentrePoint Data Hub (CP Data Hub) leverages several technologies to facilitate the reliable transfer of both
raw and summary data collected by ActiGraph activity monitors and other connected health sensors.
Bluetooth®
Data transfer from peripheral devices to the CP Data Hub is supported by a dual-mode Bluetooth®
Smart Ready (v.4.0) (Classic and Low Energy) chipset capable of data rates approaching 25 Mbit/s.
This is sufficient for capturing continuous-time epoch level (1 sample/minute/axis) activity data
throughout the day without the need for user interaction.
USB 2.0
Raw activity data (up to 100 activity samples/second/axis) is transferred to the CP Data Hub through
a USB 2.0 high-speed connection (480 Mbit/s), which is capable of handling the large data payloads
generated by ActiGraph’s activity monitors while simultaneously charging the device battery.
Cellular
Data collected from in-home peripherals are transferred via cellular network into ActiGraph’s secure
CentrePoint study management system. The CentrePoint Data Hub leverages a global UMTS/HSPA/
GSM 3G cellular radio capable of operating on a global scale with supported data-rates of 7.2 Mbit/s
(down) and 5.76Mbit/s (up) in an extended operating range of -0 to +60 C. Fallback bands include
GSM 850/1900 and 900/1800 MHz; GPRS Class 12 CS1-CS4 (up to 85.6 kbit/s); EDGE Class 12, MCS1-9
(up to 236.8 kb/s); CSD GSM (max 9.6 kb/s); and UMTS (max 64 kbit/s). Certifications and approvals
include PTCRB, GCF, FCC, IC, R&TTE, RCM Anatel, and AT&T.
Ethernet
An optional 10/100 Base-TX ethernet connection is also available for non-cellular applications.
Microprocessor
The CentrePoint Data Hub core processor is a 32-Bit ARM® Cortex®-A8 RISC Microprocessor (IC Sitara™)
supporting an embedded Linux OS.
Data Security
All protected health information (PHI) is encrypted and stored securely in the ActiGraph cloud
database. Connections are made securely using PKCS #1 SHA-256 with RSA Encryption. No PII is
transferred.
Power
The CentrePoint Data Hub has a power rating of 5V and 2.5A. V means DC voltage.
Temperature
The CentrePoint Data Hub has a temperature range of 0°C to 60°C.
