The National Instruments CA-1000 is a configurable enclosure
designed for maximum user-defined I/O connectivity and flexibility.
It is a portable enclosure for laptop, desktop, and rack-mount
applications. You can install many NI accessories in the NI CA-1000,
such as the SC-204x signal conditioning products, and the SCB-68,
CB-68LPR, and CB-50LP terminal blocks. The result
is a compact, portable, flexible, and comprehensive signal
conditioning/interconnection system. The CA-1000 also facilitates
quick connection and disconnection with standard I/O connectors
for easy system integration and reconfiguration. By adding interface
panelettes, such as toggle switches, potentiometers, and LEDs, you
can control and verify system operation locally.
Internal Accessories
The CA-1000 houses a variety of signal conditioning and data
acquisition accessories, including the SC-204x, SCB-68,
CB-68LPR, and CB-50LP. You mount these accessories using
hardware in the bottom panel of the CA-1000 enclosure. To install
the SCB-68 in the CA-1000, you must first remove it from its own
metal enclosure.
I/O Panelettes
The CA-1000 includes a user-configurable signal connection
scheme. This connectivity flexibility is achieved with
interchangeable panelettes. The panelettes, which come with
standard signal connectors – for example, BNC, SMB, banana jack,
thermocouple plugs, and LEMO, MIL-Spec, and 9-pin D-Sub
connectors – mount in the front of the CA-1000 enclosure.
The CA-1000 front panel offers nine panelette slots. The rear panel
can also be removed offering nine more panelette slots. However,
this option is not available if you are using the SCB-68 inside the
CA-1000. You can mix and match different types of panelettes. Each
panelette (except for the strain-relief panel) includes lead wires that
you connect to the screw terminals of the accessory mounted inside
the CA-1000. You can therefore connect the panelettes to any I/O
signal available on the accessory.
CA-1000 Enclosure
The metal enclosure provides a low-profile, portable housing for
signal conditioning and connector accessories. You can place the
enclosure under a laptop PC, on a benchtop, or in a 19 in. rack.
You can also stack two or more enclosures with the stacking kit.
The CA-1000 enclosure includes five cable entry options, so you can
place the 68-pin or 50-pin connector for the cable to your DAQ
device on either the side or the rear of the CA-1000 enclosure. Please
note that the CA-1000 is shipped without any panelettes, signal
conditioning accessories, connector blocks, or cables. These
components must be ordered separately.

Interface Panelettes
National Instruments also offers interface panelettes, which expand
the functionality of the CA-1000. Interface panelettes include
traditional interface controls and displays, such as rocker switches,
toggle switches, momentary switches, potentiometers, and LEDs.
Using interface panelettes, which are mounted alongside I/O
panelettes, you can change hardware inputs, trigger events, or verify
operational status. Each interface panelette includes lead wires for
connection to the screw terminals of the accessory mounted inside
the CA-1000.
Cabling
The cabling needed to connect the CA-1000 to the measurement
device depends on the accessories installed in the CA-1000 and the
measurement device used. Some accessories installed in the CA-1000
require internal cabling to connect the accessory to the CA-1000 wall.
Use Table 1 to determine which cabling components you need,
including the cable to your measurement device.
The CA-1000 also provides the flexibility of five external
interconnection locations, giving convenient cabling for laptop
applications by aligning the I/O connector with the location of the
PCMCIA slots on laptop computers. With the five external
interconnection locations, you can also customize desktop and rack-
mount applications for added convenience.
