 The
PCI PC Watchdog board is a short PCI card that monitors a PC for
hardware/software lock-ups to ensure maximum system availability.
It provides a solution for Telecom, ISPs, Voice Mail, File Servers,
and Industrial systems that occasionally lock up but must be available
on a continuous basis.
The
card has the following features:
- Now
supports ATX PCs without a reset switch.
- Reset
adapter boards available for some Dell computers.
- Single
8 bit A/D input.
- Eight
bytes of non-volatile memory reserved for user data to implement
simple software protection
- PC
Watchdog timer that can be set from 5 seconds to 1 hour via DIP
switch or 1 second to 18 hours via software control.
- Eight
(8) I/O ports for enhanced PC Watchdog control and monitoring.
- Two
on-board relays (DPDT - 2 form C) can be programmed to generate
a 4-5 second pulse or latch on continuously after a PC Watchdog-initiated
reset.
- Four
(4) general-purpose digital inputs.
- Four
(4) general-purpose digital outputs.
- External
PC Watchdog re-trigger digital input.
- Relay
contacts and digital I/O signals available on standard DB-25 connector.
- There
is a non-volatile memory for saving configuration data.
- Over
temperature circuit monitors the internal temperature of the PC.
- Two
temperature trip points.
- Trip
points can be modified by user software.
- Audible
alarm and external digital output for the temperature trip point.
- Programmable
options allow the PC Watchdog to hold the PC in reset after the
upper trip occurs.
- Two
externally visible LEDs show status of PC Watchdog board. One LED
lights after first PC Watchdog-generated reset as a visible indication
that a PC Watchdog reset occurred.
- An
I/O port allows the user to gain exclusive control of one relay
from a user program.
- Programmable
power-on delay to allow the PC to complete its initialization sequence
The PC Watchdog board only requires
that you have a PCI slot available and a PC with a reset switch. The
reset cable is disconnected from the motherboard (CPU) and plugged into
the PC Watchdog board. A cable is provided to go from the PC Watchdog
board to the motherboard. When the PC locks up and the PC Watchdog times
out, then it will perform the equivalent of a push-button reset.
The PCI PC Watchdog ships with
utility programs for control of the board. Source code is provided
for all included software. The PC Watchdog works with most any
operating system on a PC. Libraries and drivers are provided for
Visual "C" and Visual Basic under Win 95-98-ME-NT-2000 & XP.
It also has LINUX support.
