This high quality pc watchdog board is now also available for the USB bus. We designed the board as an Plug&Play compatible USB-card. The board has 2 switchover relays that allow a wide area of usage (i.e. switch external modem, inverted operation). Additionally, the board can handle pc motherboards without a reset switch. We included drivers for the following operating systems on CD-ROM: Microsoft Windows XP / 2000, Microsoft Windows 98 / ME.
For Microsoft Windows XP / 2000, an additional NT service (WDSERV.EXE) is supplied which works as a background process. The WDSERV is an addon for machines that require 24 h availability. The WDSERV Windows XP and Windows 2000 NT Service executes the nescessary accesses on the watchdog in the background. After a system crash, the system will be rebooted automatically. The program works totally in the background, so nobody has to be logged on at the machine.
The USB watchdog board is supported by the QLIB (QUANCOM Driver Library), and therefore allows an easy programming under varios operating systems. To support developers, we included a driver installation toolkit for OEM manufacturers or software developers.

WDSERV 24/7 Background Service for QUANCOM Watchdogcards
The WDSERV is an add-on for machines that require 24 h availability. The WDSERV
NT 4.x, Windows 2000 and Windows XP service executes the necessary accesses on the
watchdog in the background. After a system crash the system will be rebooted
automatically. The program works totally in the background, so nobody has to be
logged on at the machine. The WDSERV service itself has no user interface and no
components that need configuration. [Download 3,7MB]

Additional information

•Description
|
The watchdog board is used for the functional monitoring of a personal computer. If the PC or a software running on the PC does not react any longer (i.e. crashes), the watchdog card switches the relay(s) on. The first relay generates a hardware reset of the personal computer. The PWDOG2N and WATCHDOG2 are additionally able to
switch an external device (i.e. modem, router, etc.) with the secondary relay off and on.
How the watchdog board works
The watchdog board supervises the personal computer. The watchdog card constantly tests the function of a program running on the PC. If the personal computer and therefore the program crashes, the watchdog resets the computer. The software running on the personal computer must execute a function call to the sofware library in a determined interval. The minimum access time is adjustable on the board by the DIP switch. The user can choose the following intervals: 30 ms, 0.5s, 4 s, 16 s, 1min, 4 min, 8 min or 12 min. The PWDOG2N allows an adjustable timeout interval up to 14,3h. If the time between two accesses is longer than the specified timeout interval, the board switches the relay on and short circuits the reset switch on the motherboard. To be exact the relay short circuits the left two connectors of the Jumper 1 (JP1) and parallel to it the connectors of the Jumper 2 (JP2). The relay hold time can be set by the DIP switch for 0,5, 2 or 8 sec.
The heart of the watchdog boards is an isPLSI of the company Lattice who allows the great variety of variable time-out times. A 6MHz oscillator contained on the card serves as a time base.
Control elements and LEDs
The green light emitting diode present at the card (LED green) lights up from the moment when the board is enabled by the software. This shows that the watchdog card is activated. The red light emitting diode (LED red) lights up when the timeout event occurs.

•Areas
|
Watchdog boards are employed by systems which must be constantly in operation for check. So e.g. in process and production check, during other applications relevant to security or also in the case of mailbox programs.
