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.
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). A status register indicates normal or high temperature and can also generate an interrupt. The temperature measurement circuit uses an on-board 8-bit A/D as the digitizer. 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. In parallel to these two isolated outputs are two non-isolated digital outputs that can sink/source up to 15mA and can drive LEDs to indicate the switched event of the isolated outputs or simply output to another device the same digital state. A fused 5V external power pin is provided to bias external LEDs when used with non-isolated digital outputs. A push button reset input is also provided to directly initiate a system reset.
