This board installs in a standard or a low-profile PCI (5V, 3.3V and PCI-X) slot and monitors a PC for hardware/software lock-ups or computer malfunctions.

PCI PC WatchdogTM Timer Description

The PCI PC Watchdog 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 PCI 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 PCI PC Watchdog works with
Win 2K XP Vista Win7 Win 8 Server2003 Server2008  (32 & 64 Bit Versions on all). It also has LINUX support.

As well as functioning as a watchdog timer, the PCI PC Watchdog board also provides additional user I/O on the DB-25 connector on the rear of the board. The I/O is configured by DIP switch options as well as user provided software.

The board meets the dimensions for the PCI MD1 (low-profile) specification for use with small PC cases.
The board can be ordered with a low-profile bracket for use in a low-profile case or it can be ordered with a standard size bracket for regular PC cases. It has a universal PCI interface that works with +5.0V and +3.3V PCI slots. It also works with PCI-X (not PCI Express) slots.


  • Watchdog timer can be set for 5 seconds to 1 hour by DIP switch or 1 second to 18 hours via software control.
  • Can be used right from the box with supplied programs.
  • Has an on-board temperature sensor to detect fan failures or other over-temp conditions.
  • Has two temperature trip points for alerting.
  • Programmable option to allow the PC Watchdog to hold the PC in reset after the upper trip occurs.
  • Audible alarm for the temperature trip points.
  • The temperature trip points can be modified by user software.
  • Two externally visible LEDs show status of PC Watchdog.
  • Programmable power-on delay to allow the PC to complete its initialization sequence.
  • Non-Volatile memory to store operating parameters.
  • Eight bytes of non-volatile memory reserved for user data to implement simple software protection.
  • Two relays (DPDT - 2 form C) with contacts available on the DB-25 connector.
  • Relays can be set for 3-4 second pulse or continous latch on after a PC reset.
  • One relay can set for 3-4 second pulse or continous latch on after an overtemp.
  • Four (4) general-purpose digital inputs (TTL Level) on DB-25 connector.
  • Four (4) general-purpose digital outputs (TTL-OC Level) on DB-25 connector.
