4. Functionality
The PCI-EXP-WDOG2 functions as a hardware watchdog controller that monitors system activity and automatically initiates corrective actions if the system becomes unresponsive. The watchdog timer is configured via software to a specific timeout interval. During normal operation, the host system periodically resets the watchdog timer (“kicks” or “feeds” the watchdog). If the system fails to reset the timer within the programmed interval—indicating a potential system hang or crash—the watchdog triggers one or both relay outputs.
These relays can be connected to the system’s ATX power control lines using the included adapter cable, enabling automatic system reset or power-off/power-on cycling. Alternatively, the relays can be used to activate alarms, signal external controllers, or trigger redundant systems.
Use Cases and Applications:
- Industrial automation systems requiring autonomous recovery from software or hardware faults
- Embedded control systems in remote or unattended installations
- Network servers and gateways requiring high uptime and automatic reboot capability
- Process control and monitoring systems in manufacturing environments
- Data acquisition systems where continuous operation is critical
- Kiosk, digital signage, or point-of-sale systems that must recover automatically from system hangs
