Chapter 2 Functional Overview
© National Instruments Corporation 2-3 VXIpc 800 Series User Manual
The VXIpc 800 consists of the following logic blocks:
Video The video circuitry is a plug-in PCI card that has
a 64-bit data path to up to 4 MB of EDO DRAM.
IDE This is dedicated PCI-IDE circuitry providing
fast ATA-2 transfers to the internal hard drive.
PCMCIA This is a dedicated PCI-PCMCIA interface that
supports two independent PCMCIA cards. One
socket can accommodate a Type I, II, or III card
while the other accommodates a Type I or II
card.
VXI This is the PCI-VXIbus interface circuitry.
The MITE is a National Instruments ASIC
developed to efficiently manage data transfers
between the VXIbus and the processor (via the
PCI bus). The MANTIS ASIC (also developed
by National Instruments) performs VXIbus
arbitration and manages interrupts and triggers.
Also part of the VXIbus interface are the SMB
connectors, which you can use to route triggers
and the CLK10 signal to or from the VXIbus.
Ethernet This is an ISA-based Ethernet circuit on the
VXIpc 800 Series. It uses an RJ-45 connector
for access to an external Ethernet-based LAN.
GPIB This logic block represents the IEEE 488.2 port
on the VXIpc 800 Series. It uses the National
Instruments TNT4882 ASIC for maximum
performance as an ISA-based GPIB controller.
PC Peripherals These blocks represent the other peripherals
supplied by the VXIpc 800. The VXIpc 800
Series has PS/2 mouse and keyboard ports, two
miniature serial ports, and ECP/EPP parallel
port, speaker jack, reset button, and a 1.44 MB,
3.5 in. floppy drive.
