USB PC Watchdog Timer Description

This is a small circuit card that mounts inside the PC and monitors a PC for hardware/software lock-ups or computer malfunctions. It provides a solution to reboot PC file servers, telecom, security, kiosk, video surveillance, digital signage and industrial systems that occasionally lock up but must be available on a continuous basis. Increase your system availabilty and protect against unexpected downtime or blue screens (BSOD).

The USB PC Watchdog timer ships with utility programs for control & "tickling" of the board. Sample source code and libraries are also provided in Visual "C" and Visual Basic to allow users to write their own applications to configure or "tickle" the board. Use the CD image download below to see the samples provided along with all the programmer's documentation. The USB PC Watchdog works with Win 2K XP Vista Win7 Win 8 Server2003 Server2008  (32 & 64 Bit Versions on all). It also has LINUX support.

There is also a 4-Pin internal header behind the regular USB connector and an additional mounting hole. This allows it to be installed inside a PC and make a connection to the internal header on the motherboard. If the bracket is removed there are three mounting holes available. The board is so small and light that could also be secured inside the PC with double sided velcro tape. There is a mechanical drawing for the mounting holes available on the CD image download. The PN: 1140-1 version is supplied with a 22 inch (558mm) cable for the internal connection.
