PALconnect User Guide

Setup new recording

From the connection screen select ‘Setup New Recording’.

If at least one of the devices has not yet been erased, recording setup will be prevented.

If the device battery level is low you will receive a warning message to indicate the full recording duration may not be reached. 

Enter recording parameters

Immediate start

With ‘immediate’ checked, the activPAL will start recording immediately on removal from USB.

Parameters:

  • duration: specify the duration of the recording on days, hours and minutes
  • identifier: this is an optional identifier to the data file which is both stored as part of the data file and the filename on download
  • mode: uses the current settings for this device type
  • PALtransfer: enable the device data to be transferred to the cloud remotely by participants using the PALtransfer app

On clicking ‘Confirm settings’ the progress screen will display, indicating the chosen parameters

On successful setup, remove the activPAL from USB.

The green light will flash to show the recording has started. When the recording has stopped, the activPAL will stop flashing. 

Start at programmed time

With the ‘immediate’ box unchecked, the activPAL will start recording at a specified time.

Parameters:

  • date: the start date of the recording
  • time: the start time of the recording using the 24 hour clock (Note 0:00 is midnight, 12:00 is midday) 
  • duration: specify the duration of the recording on days, hours and minutes
  • identifier: this is an optional identifier to the data file which is both stored as part of the data file and the filename on download
  • mode: uses the current settings for this device type
  • PALtransfer: enable the device data to be transferred to the cloud remotely by participants using the PALtransfer app

The activPAL can be setup to start up to seven days in advance.

On clicking ‘Confirm settings’ the progress screen will display, indicating the chosen parameters

On successful setup, remove the activPAL from USB.

The activPAL will flash orange to show that it is set to start at a future time. At the programmed time, the orange light will stop flashing, and the green light will flash to show it is recording. When the recording has stopped, the activPAL will stop flashing. 

Setting up recordings on multiple devices

Up to 7 devices can be setup for recording at one time using an activDOCK. The same recording parameters are applied to all activPALs.

Download recorded data

From the connection screen select ‘Start Download’

An optional download identifier can be set which is both stored as part of the data file and the filename on download.

The data is then downloaded from the activPAL to the folder as specified in the Setttings

Once the data file has been downloaded a simple display of wear-time is displayed. A bar is shown for each day of the recording: wear time is indicated in orange, non-wear in grey. The wear time in hours is shown below each bar.

The number of valid days in the recording are displayed as an indicator of data quality (using a 24 hour wear protocol). In the example below, there are two full days of wear, two partial days, and three days where the device was taken off.

The ‘view file’ button launches an instance of PALanalysis for data visualisation and export of the analysis outcomes. 

Downloading from multiple devices

The data from up to 7 devices at a time can be downloaded using an activDOCK.

The wear-time display is shown as a list. In this example all activPALs were worn for the full 7 days of the recording.

Performance test

This test procedure will place the activPAL in a “high-burn” mode where a fully-charged healthy battery will be depleted in 4-5 days.  This allows an assessment of battery health to be undertaken in a compressed time frame (a fully-charged battery in new condition will record for ~4 weeks).  The results can be viewed in summary form in the activPAL performance dashboard.

To begin, click on “Start Performance Test” in the menu.

The 7 day performance test provides a convenient measure of battery capacity when the accelerated testing function is used.  In the performance test the battery will drain in >4.5 days compared with >21 days in typical operation.

To perform a full performance test

  1. Charge for 2-3 hours (until the amber light goes out)
  2. Click the “Start Full Test” button

During the recording period of the performance test you will notice the lights on the activPAL are on constantly.  This is a normal part of the test and indicates the activPAL is in performance test mode

When the lights on the device turn off, the performance test is complete. For devices with high battery performance, this should take around >4.5 days. The purple bars below indicate the health of the battery.

Firmware update

If an activPAL firmware update is available, then a prompt will be provided to update the device. Updating the firmware is recommended to get the latest device performance and reliability improvements.

Do not disconnect the device or close the software during the firmware update.

Settings

The following settings can be adjusted for PALconnect:

  • data transfer folder – the folder where datx files are placed when downloaded
  • recording modes – the device parameter settings by device type
    • aP3 options
      • [20.2] (20Hz 8bit +/-2g)
    • aP4 options
      • [20.2] aP3 compatible (20Hz 8bit +/-2g)
      • [20.4] aP4 default (20Hz 10bit +/-4g)
      • [50.4] aP4 50Hz (50Hz 10bit +/-4g)
    • aP4+ options
      • [20.2] aP3 compatible (20Hz 8bit +/-2g)
      • [20.4] aP4 compatible (20Hz 10bit +/-4g)
      • [50.4] aP4 compatible (50Hz 10bit +/-4g)
      • [20.4mb] aP4+ default (20Hz 10bit +/-4g, +magnetometer, +barometer)
      • [50.4mb] aP4+ 50Hz (50Hz 10bit +/-4g, +magnetometer, +barometer)
  • Enable erase for supported devices – The latest firmwares for the aP4 and aP4+ devices support memory erase. With this option checked (recommended), then the activPAL must be erased before setting up a new recording. This can be disabled to allow recording setup with recording data still on the device.
  • Enable aP4 40Hz mode (deprecated) – This enables the deprecated 40Hz mode as an option. 50Hz is the recommended higher sampling frequency mode.
