the other accommodates a Type I or II card.
On the VXIpc 700 Series, you can install two
Type I or II cards or one Type III 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 and VXIpc-745. 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 and VXIpc-745. 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 800/700. 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. Refer to the Front Panel
Features section of Chapter 1, Introduction, to
see which of these apply to the models in the
VXIpc 700 Series.

CPU Card
The modular architecture of the VXIpc 800
Series contains a plug-in CPU card that can
accommodate various Pentium/Pentium
Pro-class processors. This card includes the
