This multifunction Low Profile x1 PCI Express 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. The card is 6.6 inches long and 2.535 inches seated height. I/O wiring connections are via a female DB25 connector on the card mounting bracket. Two models with increasing features are available.
The PCIe-WDG-CSM card contains a watchdog timer and on-card RGB LED and speaker alarm to signal watchdog timeout. A DPDT relay, two LVTTL inputs and two outputs, and fused 3.3V general purpose outputs are accessed via the DB25 female I/O connector on the card mounting bracket.
An advanced model, the PCIe-WDG-CSMA, is also available which includes an A/D converter to monitor the computer power supply, and sensors to monitor the internal temperature and humidity, ambient light, and comes with a remote temperature sensor on a 19” cable. A pair of opto-isolated outputs and four opto-isolated inputs are available for general purpose use.
PCIe-WDG-CSMA: Advanced Feature Pack* Advanced software package multiplies the power of your Watchdog.
Create a customized configuration package and upgrade your PCIe-WDG-CSMA device to:
- Protect your computer from common problems that can occur during power-on self test (POST)
- Control one or more outputs when input(s) toggle or other Events occur
- Schedule output changes to occur periodically or at a specific time
- Play WAV files when Events happen, including Growl, Bark, “LVTTL0 falling edge detected”, etc.
All features can be configured through either a Windows GUI-based settings program or our flexible AIOWDG.dll API, with settings stored in onboard non-volatile memory.
The PCIe-WDG-CSMA is designed for use in both industrial/commercial and optionally military environments of 0 to +70°C and -40 to +85°C, respectively. Programmable array logic is available on this card and many possibilities exist for special modifications to suit unique requirements.
The PCIe-WDG-CSMA is supported for use in most operating systems and includes a free Windows and Linux (including macOS) compatible software package. This package contains sample programs and source code in C#, Delphi, and Visual C++ for 32-bit and 64-bit Windows. Also provided is a graphical setup program in Windows. Linux support includes installation files and 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 LabVIEW VIs. Embedded OS support includes the family of Windows Operating Systems including IoT, please contact ACCES for compatibility with your specific OS.
