Operating the CentrePoint Data Hub

Setting up the CP Data Hub in the home (instructions for subjects)

1. The CP Data Hub should be placed in a location where the subject spends a lot of time.
2. 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.
3. 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.
4. 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.
5. Once the CP Data Hub is successfully connected, plug the Link dock into the USB port on the side of the CP Data Hub.

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. https://actigraph.desk.com/customer/portal/articles/2830405-raw-and- summary-data-explained

Wireless 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.

1. If a full day’s worth of data is downloaded, it will be immediately transferred to the CentrePoint system via 3G cellular network.
2. 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 configured for each study.

Raw data uploads (USB)

The CP Data Hub can be used to upload raw actigraphy data using the Link dock.

1. 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.
2. 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.
3. Summary one-minute epoch data and the raw data file (if applicable) are immediately available in CentrePoint. See “Viewing uploaded data” section below.

Charging the activity monitor

The CP Data Hub charges the ActiGraph Link battery anytime it is placed in the connected dock.

1. During charging, an animated battery icon will appear on the ActiGraph Link screen and the charging dock will display a yellow LED.
2. Charging is complete when the LED turns green.
3. If the dock displays a red LED, this indicates a charging problem. Remove and reinsert the activity monitor in the dock.
4. It takes approximately 2-3 hours to charge a fully depleted battery.

Managing the CentrePoint Data Hub in CentrePoint

Viewing upload details

1. All CP Data Hub data uploads (wireless and raw data) are instantly logged in the “Activity Feed” on the “Study Home Dashboard” page.
2. To view detailed upload information for a subject, go to the “Subject Details” page and select “Subject Timeline.” Each timestamped data upload is logged and the amount of new data, activity monitor battery level, and upload source (CP Data Hub Bluetooth® or USB) are provided.

Viewing uploaded data

1. After the CP Data Hub performs a successful data upload (Bluetooth® or USB), the epoch summary data is immediately available to view.
2. From the “Subject Details” page, select “Subject Data Report” from the dropdown list to view daily wear compliance, calories, and steps. Select the date link to view minute by minute daily details.
3. If raw data has been uploaded via the CP Data Hub (USB), the file can be downloaded by going to the “Subject Details” page and selecting the “Raw Data Downloads” tab. Select the desired file(s) and click download. The raw data is stored in a .gt3x file, which can only be opened using the ActiLife desktop analysis software.

Note: CentrePoint is a role-based system and certain user types can be configured to view wear compliance data only.

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.

1. 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.

2. 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.

3. 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.

4. Ethernet

   • An optional 10/100 Base-TX ethernet connection is also available for non-cellular applications.

5. Microprocessor

   • The CentrePoint Data Hub core processor is a 32-Bit ARM® Cortex®-A8 RISC Microprocessor (IC Sitara™) supporting an embedded Linux OS.

6. 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.

7. Power

   • The CentrePoint Data Hub has a power rating of 5V and 2.5A. V means DC voltage.

8. Temperature

   • The CentrePoint Data Hub has a temperature range of 0°C to 60°C.
