External Button Event Handling
APDM oers an optional button that ts into the data port of an undocked sensor. The button allows for additional
functionality while recording including insterting event markers into the data stream, and stopping and starting
recording.
Enabling the Button
The button is enabled via the Sensor tab in the conguration dialogue box. After undocking a sensor with button
handling enabled, you must insert the button into the data port on the sensor. The button must be removed before the
sensor can be docked.
Event Markers
The external button provides the ability to record the time of external events directly into the data stream for oine
analysis. Pressing the button will insert the button state (up/down) into the data stream of the sensor the button is
connected to. A maximum of one button transition (on/o or o/on) can be recorded every 10ms. The button state
is stored on a sample-by-sample basis in the output le. Both CSV and HDF le formats support the storage of the
button state. A value of 1 indicated that the button is pressed, while a value of 0 indicates that the button is not
pressed. If you are using one of the streaming modes, the current button state is indicated in the “Button State” eld
in the Stream Dialogue (make sure you have selected the correct sensor in the “Select Sensor” drop-down when
viewing the button state). This is a good way to test that the functionality is working.
Starting and Stopping Recordings
If the button is held down for at least 3 seconds, the sensor will transition into a “hold” mode where recording is
halted. The LED will indicate this mode by a slow blue blink pattern. If the button is released and held for another 3
seconds while halted, the sensor will start running again and a new recording will be started. If one sensor is in hold
mode, any other sensors will continue to record. The sensors will remain powered up. The external button is best used
for starting and stopping recordings when using a single monitor in the low power logging mode.
