A Watchdog timer that monitors a PC for hardware/software lock-ups via serial port activity.
This device is used outside of a PC or other type of computer and monitors for hardware/software lock-ups. It is typically used to cycle AC power (with a power module) on the computer to initiate a restart or reboot. It also has a dry conact relay output available for other timing options. See the Accessories section for the AC Power Modules.
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 Serial 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 Serial PC Watchdog works with Win 2K XP Vista Win7 Win 8 Server2003 Server2008 (32 & 64 Bit Versions on all). It also has LINUX support.
The External Serial device has been upgraded so it now supports temperature sensing, non-volatile memory for device configuration, and faster Baud rates. It can now support features similar to the ones found in the USB or PCI PC Watchdog.
This device has been tested with USB to Serial devices based on the FTDI & Prolific chips. It should work fine with other versions also. The board does ship with a 6 foot DB-9M to DB-9F cable.
Since the External Serial PC Watchdog is outside the PC case, it needs a source of DC voltage to operate. For North American customers a 110V style is supplied. For international customers you should order the universal type (110-220VAC) with multiple plugs shown on this page.
If you would like to source your own AC/DC adaptor then this is what you need:
Output: 6.0 - 12V DC - 100mA minimum - 2.1mm power plug with center pin positive (+)
You can choose the option supply your own adaptor and we will issue a credit off the price (see options above).
The dimensions shown on the specifications tab are for the product box.
The actual size of the extruded aluminum enclosure is: 3.3"W x 1.13"H x 2.31"D (83.30mm x 28.75 x 58.68mm)
