Intelligent Watchdog Timer Board It's a fact that the PC hardware and software may fail. To prevent the failure,many different solutions are proposed. However, none of these solutions offer a 100% assurance. Since it's 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 of PC failure. The WDT-03 is useful even for those systems with built-in watchdog circuit.
The WDT-03 is equipped with two RS-232 ports, one is master port and another one is slave port. The master RS-232 port is designed to communicate with the local host-PC. The local host-PC can enable/disable/refresh/read-back the watchdog timer through the master RS-232 port. The slave RS-232 is used to send information to the remote Host-PC for monitoring. SO the remote HOST will get information immediately if the local host-PC has any software or hardware problem, even the power is failure
