  • This multifunction card contains a watchdog timer used to monitor the operation of your application program and operating system to initiate a system reset in case of a lockup. It can also monitor and control a variety of system hardware parameters. Three models with increasing features are available.

    P104-WDG-E: Economy version which includes the full programmable watchdog timer with open collector outputs that can reset the computer.

    P104-WDG-CSM: The Computer Status Monitor (CSM) version includes features in the economy model and adds capability to monitor the health and control various computer functions. The PCI-Bus 5V and ▒12V are monitored and if any voltage varies by more than 6%, an interrupt can be generated. The temperature monitor compares an on-board temperature sensor output to a preset reference (approximately 50░C). This model also provides one general-purpose opto-isolated input. Two digital isolated outputs are provided to control/switch external events in response to CSM conditions.

    P104-WDG-CSMA: This advanced version builds on the P104-WDG-CSM but has all available features populated. Two undedicated 8-bit A/D (Analog Inputs) with a 0-5V range can be used to measure critical system parameters such as battery voltage or humidity.
