Watchdog
SQN3223 chipset provides internal software Watchdog, and a physically dedicate Watchdog
circuit requirement is optional.
The circuit includes is MCU that acts as a failsafe external watchdog. The MCU power cycles
the system, if no activity is detected for 2 hours.
Motion Detect (Option)
A factory populates option for motion detector is provided. If populated at the time the TALON-
LTE is manufactured, this option will work with firmware power down options to keep the
TALON-LTE in a very low power down state until motion is detected. Upon wakening, a report
can then be generated.
