USB Watchdog Driver installation ================================ The USB watchdog driver (usb_wdog.sys) is a customized version of Thesycon's usbio_el.sys driver. Refer to the documentation installed by '\Thesycon\usbio_el\setup.exe' for a description of the driver features. Since the driver is a true PnP driver installation should be quite straight forward under Win2K and Win98. Upon detection of the USB watchdog device, point the hardware wizard to the root directory of this CD to find the 'usb_io_karo.inf' file and 'usb_wdog.sys' driver. You may then use one of the sample applications in the directory 'Watchdog Applications' to check out the correct function of the device. Watchdog Device Description =========================== The watchdog device waits for a message on the USB port that consists of the string 'KARO' followed by two 16bit numbers. The first number gives the number of seconds before the watchdog will activate the hardware reset. The second number is the ones complement of the first number. Byte ordering is little endian. Once such a message has been received, the device will count down and activate the reset switch for 3 seconds, when the specified time elapses without having received another trigger message. Watchdog example applications ============================= Dialog based application ======================== The dialog based application 'WatchdogCtrlDialog' is quite self explanatory (I hope ;). Command line applications ========================= 'wdstatus' reads the current state of the watchdog state machine and returns the remaining runtime until reset, if the watchdog has been triggered previously. 'wdtrigger' takes a number (0 .. 65535) as argument and winds up the watchdog by this the number of seconds. '0' will immediately trigger a watchdog reset! Default, if no argument given is 30 seconds. 'wdcontrol' takes two arguments and will constantly monitor the watchdog device and wind it up for the number of seconds given as the first argument, whenever the remaining runtime until reset drops below the number of seconds given as the second argument. By specifying 0 for the second parameter, the watchdog will only be retriggered, after the reset has been activated. This may be used to test the correct functioning of the watchdog device. The reset output of the device should not be connected to the PCs reset switch in this case!Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.

If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
