Watchdog Connection
Picolo Alert provides a hardware watchdog. Its purpose is to monitor the software application and to restart the computer after an anomalous inactivity time-out. This ensures a reliable operation of unattended systems.
Watchdog connectors
A reset cable can be connected directly to the watchdog connectors, 2 internal 2-pin headers. Both connectors are equivalent and the polarity of the watchdog outputs doesn't matter.
The watchdog outputs can also be used for other purposes than resetting the computer, for example, to activate an alarm. See I/O Operation for the operation of I/O lines.
