ISA PC Watchdog Timer Description

This board is a short 8-bit ISA card that monitors a PC for hardware/software lock-ups to ensure maximum system availability. It provides a solution for file servers, telecom systems, kiosks, video surveillance systems, industrial applications, etc. that occasionally lock up but must be available on a continuous basis. The PC Watchdog board only requires that you have an 8-bit ISA slot available and a PC with a reset switch. The reset cable is disconnected from the motherboard (CPU) and plugged into the PC Watchdog board. A cable is provided to go from the PC Watchdog board to the motherboard. When the PC locks up and the PC Watchdog times out, then it will perform the equivalent of a push-button reset. The PC Watchdog board ships with utility programs and APIs for control of the board. Source code is provided for all included software. The PC Watchdog works with most any operating system on a PC.
Drivers for DOS and Win 95/98/ME/NT/2K & XP are included. It also has built-in LINUX 2.0 (and higher) support.
