NuPRO-842
Watchdog Timer
The watchdog timer optionally monitors system operations. It can
be programmed for different timeout periods (from 1 to 255 sec-
onds or 1 to 255 minutes). The watchdog is capable generating a
Reset signal. Failure to strobe the watchdog timer within the pro-
grammed time period may result in a reset request. A register bit
can be enabled to indicate if the watchdog timer caused the reset
event. This watchdog timer register is cleared on power-up,
enabling system software to take appropriate action if the watch-
dog generated the reboot.
Video
The NuPRO-842 provides two display ports. One analog port is
output on rear IO panel. The analog port uses an integrated 350
MHz RAMDAC of the 845GV GMCH that can directly drive a stan-
dard progressive scan monitor up to a resolution of 2048x1536
pixels with 32-bit color at 60 Hz. The NuPRO-842 has a
high-speed interface to a digital display use daughter board
DB-842DVI. The Intel 845GV chipset implements Dynamic Video
Memory Technology (DVMT) to ensure the most efficient use of
system memory, allowing up to 64MB of system memory to be
shared among OS, applications, and graphics display.
Ethernet Interfaces
The NuPRO-842 provides two 10/100/1000Mbps Ethernet ports
supplied via an Intel 82540EM chip, which are connected to the
82801DB. Each Ethernet interface is routed to an RJ45/LED all in
one Connector on the rear panel. Each LAN chip will be assigned
a unique static MAC Address. LED drive signals for Ethernet link
status and activity are routed to the same connector. The onboard
Ethernet is Wired For Management 2.0 compliance. This port is
available on the real panel.
Serial I/O
Two serial ports are supported by the NuPRO-842. The EIA232
drivers and receivers reside on board. COM1 and COM2 are avail-
able as a 10-pin header on the motherboard. Both ports will be
configured as DTE. Firmware will initialize the two serial ports as
