Wikipedia defines a Watchdog module as follows:

“A watchdog timer (sometimes called a computer operating properly or COP timer, or simply a watchdog) is an electronic timer that is used to detect and recover from computer malfunctions. During normal operation, the computer regularly resets the watchdog timer to prevent it from elapsing, or “timing out”. If, due to a hardware fault or program error, the computer fails to reset the watchdog, the timer will elapse and generate a timeout signal. The timeout signal is used to initiate corrective action or actions. The corrective actions typically include placing the computer system in a safe state and restoring normal system operation.”


G-WD-201 (Mining)

Our watchdog modules’ (G-WD-201) firmware has been customized for GPU mining. It can be used to monitor 2 mining rigs and power cycle or reset either of them should they become unresponsive after a specified timeout period, and the best part is no software or device drivers are needed on the mining rigs, which makes the module compatible with any operating system.
