Peripheral Expansion
The VXIpc 800 uses the PCI local bus and ISA bus for peripheral
expansion. The PCIbus is a 32-bit multimaster bus that achieves a top
throughput of 132 MB/s and can handle numerous peripherals. The ISA
bus is the legacy peripheral bus found on current and older PCs.
For information on installing and configuring these peripherals for use
with the VXIpc 800, refer to the
c:\images\manuals directory. The
drivers.txt file explains how to install support for each peripheral.
This directory also contains manufacturer’s documentation for the
video, PCMCIA, and SCSI peripherals. Also refer to the
readme files
for the most up-to-date information.
Table 1-1 lists the various peripherals and describes the external
connector, its bus interface, and its function.
