Connector-and-Shell Assemblies
Connector-and-shell assemblies are low-cost alternatives to SCXI terminal
blocks and are less rugged, plastic assemblies that connect signals using
solder pins.
DAQ Plug-In Devices and PC Cards
You can connect the conditioned analog signals from an SCXI system
directly to a plug-in DAQ device or DAQCard. Using SCXI multiplexing
capability, a single plug-in DAQ device or DAQCard can measure up to
3,072 conditioned analog signals.
You can use any of the following DAQ devices to control an SCXI system:
•
Multifunction I/O (MIO) and AI devices can control single-chassis or
multichassis SCXI systems consisting of any combination of analog
and digital SCXI modules. Use MIO and AI devices for systems that
require high-speed, hardware-controlled scanning.
•
You can use all E Series AT, PCMCIA, PCI, and PXI bus devices
except the 6110 and 6111 devices.
Lab/1200 Series devices can control single-chassis SCXI systems
consisting of any combination of analog and digital SCXI modules.
DIO devices can control single-chassis or multichassis SCXI systems
consisting of digital SCXI modules.
DAQ Modules
As an alternative to a plug-in DAQ device or DAQCard, you can use an
SCXI DAQ module, such as the SCXI-1200. The SCXI-1200, which is
functionally similar to the PCI-1200 and DAQCard-1200, can control
single-chassis systems with any combination of analog and digital
modules. The SCXI-1200 connects to the computer parallel port, or to the
SCXI-2000 chassis or SCXI-2400 module, which in turn communicates
with the computer using a serial port.
