|NI Introduces Industry’s First Products for Laptop Control of
Engineers now can directly control a
PXI/CompactPCI system from a laptop computer using new National Instruments ExpressCard MXI and PCMCIA CardBus
interfaces. This new capability is ideal for portable and mobile applications, such as in-vehicle data logging,
machine condition monitoring and field tests including RF spectral monitoring, in a variety of industries including
automotive and military/aerospace.
NI ExpressCard MXI (NI
PXI-ExpressCard8360) offers direct control of PXI/CompactPCI systems from laptop computers with an ExpressCard slot.
ExpressCard is the next-generation laptop interface that comes standard on many new laptop computers. The
ExpressCard standard works with both USB 2.0 and PCI Express, and host slots accept modules that use either
interface. ExpressCard MXI uses the PCI Express interface for maximum bandwidth performance. ExpressCard MXI
delivers up to 110 MB/s of sustained throughput between PXI/CompactPCI systems and laptop computers.
With the NI PXI-CardBus8310 interface, engineers can directly control PXI/CompactPCI systems from a PCMCIA
CardBus slot, available on most existing laptop computers. The new interface gives engineers the option of using the
laptop computers they currently own to control PXI/CompactPCI systems.
Both interfaces are
transparent to software applications and drivers. With embedded controllers or desktop computers with remote
controllers, engineers can implement the new laptop control solutions without changing existing software written for
use with PXI/CompactPCI systems. The ExpressCard MXI and PCMCIA CardBus interfaces provide a software-transparent
link to the PXI/CompactPCI system, delivering software compatibility with all drivers and application development
environments. For example, engineers can use them with the National Instruments LabVIEW graphical development
environment and NI modular instruments to develop portable, high-performance field test systems. Engineers also can
use the interfaces with DC-powered chassis, data acquisition modules and the National Instruments SignalExpress
interactive measurement environment to create mobile data loggers. The ExpressCard MXI and PCMCIA CardBus interfaces
work with modular instruments, data acquisition modules and bus interfaces from National Instruments, as well as
modules from the more than 65 members of the PXI Systems Alliance and additional CompactPCI module vendors.
PCI eXtensions for Instrumentation (PXI) is an open specification governed by the
PXI Systems Alliance (www.pxisa.org) that defines a rugged, CompactPCI-based platform optimized for test,
measurement and control. It is supported by more than 65 member companies and more than 1,150 products are
available. PXI products are compatible with the CompactPCI industrial computer standard and offer additional
features such as environmental specifications, standardized software and built-in timing and synchronization.
