July 2, 2009 - ACCES I/O Products announces P104-WDG-CSMA series of dedicated watchdog timer boards for PC/104-based embedded systems. This watchdog board can be used to monitor the operation of an application program as well as operating system and will initiate a system reset in case of lockup. In addition, the P104-WDG-CSMA can monitor and control a variety of system hardware parameters such as temperature, voltage, fan speed, humidity, and more.
Applications include kiosks, industrial automation, military/mission-critical, asset management and tracking, embedded OEM, temperature measurement and many others which require self-reliant embedded systems.Supplementing the standard features expected from a watchdog timer, the P104-WDG-CSMA includes one general purpose optically isolated input, two isolated digital outputs to control/switch external events, two non-isolated digital outputs, two general purpose A/D inputs, and a security light sensor that can be used to detect if the darkened interior of an enclosure is opened.
Key features of the P104-WDG-CSMA include:
- PC/104-Plus watchdog timer card with software selectable timeout from 4 µsec
- Watchdog open collector reset outputs
- Temperature measurement, monitor, and alarm
- Fan status and speed control
- PCI/104 power monitor / limit alarm interrupt
- Opto-isolated input to trigger reset
- General purpose opto-isolated input, two outputs
- Two general purpose 8-bit A/D inputs
- External fused 5V and 12V power
- Light sensor for enclosure security
- Extended temperature (-40°C to +85°C) available The P104-WDG-CSMA is supported for use in most operating systems and includes a free software package compatible with DOS, Linux, and Windows XP/VISTA.
This package contains sample programs and source code in "C" for DOS, and Visual Basic, Delphi, and Visual C++ for Windows.
Also incorporated is a graphical setup program in Windows.
Linux support includes installation files and basic samples for programming from user level via an open source kernel driver.
Third-party support includes a Windows standard DLL interface usable from the most popular application programs, and includes example LabVIEW VIs.
Embedded OS support includes Windows XPe and CE.
