The X2 CEW captures various pieces of information about the device – this is referred to as the Trilogy log:
- Event log
- Pulse log
- Engineering log
The data set from the Trilogy log is uploaded securely to Axon Evidence services, where the information is encrypted, stored securely, and organized into dashboards that allow your agency to easily monitor the usage and system status of your entire arsenal of X2 CEWs.
Upon upload to Axon Evidence services, the system displays the information from the Event and Pulse logs. Your type of Axon Evidence account will determine what data can be viewed from these logs.
The Event log tracks events and may help protect a user from claims of excessive force by providing documentation of the time and date for each CEW deployment. The Event log also provides agencies with a powerful management tool to track usage patterns and help prevent misuse. You do not need to download the X2 CEW to Evidence.com services to obtain the Event log – the simplified Event log can be downloaded directly to your PC using the Evidence Sync (Offline) software.
The Event log includes the following information for the most recent (approximately) 16,000 entries:
- Each entry contains the date and time of each event.
- Entries include Armed, Safe, Trigger, ARC, USB connection, PowerSave mode, firmware updates, time synchronizations, PPM changes, SPPM End of Transmission, agency setting changes, etc.
- The duration of each Trigger and ARC event.
- The duration of each Safe event (when the safety switch was shifted to the down [SAFE] position and how long the CEW was armed).
- The internal temperature is shown for Armed and Safe events.
- Battery percentage is shown for all armed session events (Armed, Trigger, ARC, Safe).
- Cartridge information is shown for all armed session events (Armed, Trigger, ARC, Safe).
When the log fills to approximately 16,000 entries, it will delete the oldest 4,096 records and write new ones. This process will continue in 4,096-record increments.
The Pulse log records pulse activity of each pulse (e.g., probe deployments and Warning Arc displays). The Pulse log can help determine if the CEW's output was within specifications and determining if and when electricity was delivered to a subject.
The Engineering log monitors the performance of every key sub-system within the X2 CEW and provides alerts to the user on the CID if any subsystem is not performing properly and if maintenance is advisable. Any internal circuitry errors that occur inside the X2 CEW are written to this log. This information is used for diagnostics.
