The WDT-01 is a watchdog card that provides a watchdog timer, a temperature monitor and power monitor functions. It also provides many signals and mechanisms such as: relay control, reset signal, and a power-good signal. The power-good signal allows users to control their system as soon as errors occur. There are many signals such as: IRQ, I/O status RS-232, LED, and Buzzer. These signals alert users and operators that errors have occurred. Once the WDT-01 has been powered on, it will monitor the power and the temperature of the PC automatically. The WDT-01 monitors the operations of software and hardware after the software enables the watchdog timer. The WDT-02 is an economical version of WDT-01.
