The NI PXI-8184/8185 consists of the following logic blocks on the
CPU module and the I/O (daughter card) module. The CPU module has
the following logic blocks:
•
The
Socket 370 CPU
is the socket definition for the Intel Pentium III
processor families.
•
The
SO-DIMM
block consists of a 64-bit SDRAM socket that can hold
up to 512 MB.
•
The
Chip Set GMCH
connects to the CPU, SDRAM, and video.
•
The
SMB to PXI
Trigger
provides a routable connection of the
PXI triggers to/from the SMB on the front panel.
•
The
Watchdog Timer
block consists of a watchdog timer that can reset
the controller or generate a trigger.
•
The
Chip Set ICH2
connects to the PCI bus USB, IDE, LPC, and
Ethernet ports.
•
The
USB Connector
connects the chip set to the Universal Serial Bus
interface.
•
The
PXI Connector
connects the NI PXI-8184/8185 to the
PXI/CompactPCI backplane.
•
The
Keyboard/Mouse
block contains the PS/2 keyboard and mouse
interface.
•
The
Super I/O
block represents the other peripherals supplied by the
NI PXI-8184/8185.
The NI PXI-8184/8185 has up to two serial ports
and an ECP/EPP parallel port.
•
The
IDE
block is dedicated PCI-IDE circuitry providing fast ATA-100
transfers to the internal hard drive. The IDE feature is built into the
chip set.
•
The
10/100 Enet
connects to either 10 Mbit or 100 Mbit Ethernet
interfaces.
•
The 2.5 in. hard drive is 30 GB or larger.
National Instruments Software
National Instruments has developed several software kits you can use
with the NI PXI-8184/8185. The software is already installed on your
hard drive.
NI-DAQ has an extensive library of functions that you can call from your
application programming environment. These functions include routines
for analog input (A/D conversion), buffered data acquisition (high-speed
