Intelligent watchdog timer board
» Features
■ Don't have to modify the original program
■ Can be used in ISA bus, PCI bus and any system with RS-232 interface
■ Harsh environment detection and warning before system crash
■ Cost effective solution
» Functional Description
The PC hardware and software may fail for some reasons.
To prevent the failure, many different solutions are proposed. However, none of these solutions offer a 100% assurance.
Since it is hard to prevent the failure, to detect the failure becomes more and more important.
The WDT-03 is used to detect the failure of the software and hardware. It can be used to reduce the risk because of PC failure.
The WDT-03 is useful even for those systems with built-in watchdog circuit.
» Applications
WDT-03 provides software utility for Windows to monitor system status.
When system is damaged WDT-03 could alarm by digital output; and when system is frozen, WDT-03 could reset system automatically.
WDT-03 utility program executes when Windows start and is resident in system tray.
In NT system WDT-03 utility event could logon into administrator account automatically when windows NT is restarted.
WDT-03 utility takes very few system resources but could monitor most of the system information like voltage, temperature, fan speed and crash.
The WDT-03 can control 3-channel of digital input terminal and 3-channel of signal relay output on its dughter board DB-3R.
