Using the CPU button

This button will turn on/off the internal CPU as well as start/stop data recording.

Turning on the CPU

The CPU will turn on automatically when power is supplied to the LEMO input connector. The CPU button will light up green, indicating that the CPU is powered on. In a rare case where the CPU button does not light green after power has been supplied, the CPU can manually be turned on by a single button-press.

Shutting down the CPU

Before pulling the power connector from the unit, the CPU needs to be shut down properly. This can be done by pressing the CPU button 3 times rapidly in sequence (the status LED will flash in white color for each press). Once the CPU is completely shut down, the green light on the button will turn off. After that, power can be unplugged from the unit.

Shutting down the CPU by pressing the button 3 times will also shutdown attached LiDAR sensors the RIEGL and VUX. Please be aware that the sensors need some time to power off completely. Once all LEDs on the RIEGL sensors are off such as (13), power can be disconnected from the unit safely.

Pulling power from the system while the CPU is powered on (CPU button lights green) can lead to corruptions of the CPU or SD card file system. Always shut down the CPU properly.

In case pressing the CPU button for 3 times does not work and the CPU will not turn off, it can be force shutdown by holding the CPU button. Please note that shutting down the CPU can take up to 5 minutes after pressing the button for 3 times.

Starting data recording

Once the system has fully booted and the status LED shows as constant green, a single button-press will start the data recording with all attached sensors & cameras.

Stopping data recording

While the system is recording data, a single button-press will stop the data recording.
