JSB360 Watch Dog Timer (WDT) Module

It is a fact of life that a computer, hardware device or program may fail. To reduce the risk and possible damage a failure can cause, there is two possible methods (1) redundancy (2) watchdog timer. Neither method offer 100% protection, but both reduce risk or consequences of failure. Redundancy, a duplication of hardware is very expensive. On the other hand the JSB360 offers excellent protection at a very low cost. The host computer or application must communicate with the JSB360 by sending a message over the USB port or a hardware input line must toggle. If the communication does not occur within that programmed time frame, the JSB360 will trigger relays to change state. One (1) relay will close, another will open, and a third will close for fixed amount of time, then open. The relay events can be used to trigger a warning device, turn off critical hardware or perform a system reset. Do you have a hardware or software application that is critical to keep running at all times? Our Watchdog modules offer excellent protection against malfunctions at a low cost. Our products can be used to monitor your critical hardware and software functions (Software and Hardware) and if an error occurs, the card automatically generates outputs that can be used to initiate corrective actions, generate alarms, or reboot your computer.
Single unit cost starts at USD$ 85.5

Software
Most of our customers write their own program for controlling our devices. With our provided API's you can use any programming language that supports DLL so you do not have to learn a whole new language. We provide two types of DLL api, first is the older standard DLL with both mangled calls and "C" calls. The second is the managed Class Library that supports all the new managed languages. Any programming language that supports calls to Windows DLL can also be used to control the cards. The software interface is easy to use from Visual Basic, Visual C# Visual C++ via a standard windows DLL with sample source included. Linux driver support CD available. Each module has an unique serial number string which allows multiple USB boards to be controlled by the host USB controller as individual USB devices.
