INSTALLATION GUIDE
CA-1000 CONFIGURABLE CONNECTOR
ACCESSORY ENCLOSURE
This guide describes how to install the internal accessory, internal cable,
cable adapter, I/O panelettes, filler panels, external cables, and the optional
rack-mount and stack-mount kits with your Configurable Connector
Accessory (CA-1000) enclosure.
Introduction
The CA-1000 is a multipurpose data acquisition (DAQ) accessory
enclosure designed to optimize user-defined input/output (I/O)
connectivity and flexibility. The CA-1000 is a portable enclosure for
laptop, desktop, and rack-mount applications. You can install many
National Instruments DAQ products in the CA-1000 including:
• SC-204xand SC-207xsignal conditioning products
• CB-50LP, CB-68LPR, and SCB-68 connector blocks
The CA-1000 combined with any of these products produces compact,
portable, flexible, and comprehensive signal conditioning interconnection
systems. The CA-1000 allows you to quickly connect and disconnect
standard I/O connectors for quick system integration and reconfiguration.
The external dimensions of the CA-1000 allow you to place a laptop
computer directly on its top. In desktop applications, you can use a single
CA-1000 enclosure or stack multiple enclosures using the optional
CA-1000 stack-mount kit. An optional CA-1000 rack-mount kit is
available for standard 19 in. rack-mount applications.

Note The CB-68LPR and SCB-68 attach directly to the wall of the enclosure. The SCB-68
accommodates only a 68-pin external connection through the rear of the enclosure.
You must remove the SCB-68 circuit board from its original enclosure before installing it
in the CA-1000 enclosure.
❑One or more I/O panelettes
You do not need to configure your CA-1000 enclosure or its components
other than to decide where to put your signal connections (both input and
output in some cases). To configure your internal accessory, see the manual
for that accessory.
Installing the CA-1000 Components
The CA-1000 system consists of four components:
•CA-1000 enclosure
•Internal accessory
•Internal cable assembly (not required for all internal accessories)

Internal Cable Assembly
When connecting a 68-pin external cable to a 50-pin CA-1000 accessory
card, you must use an R68M-50F MIO Bulkhead Ribbon Cable within the
enclosure. Refer to Figure 7 and use the following steps to install the
R68M-50F MIO Bulkhead Ribbon Cable into the enclosure:
1. Choose one of the available openings for the 68-pin filler panel
according to your application.
2. Place the 68-pin filler panel inside the enclosure.
3. Secure the 68-pin filler panel to the enclosure using
two 4-40 ×3/16 in. Phillips-head screws.
4. Secure the 68M-50F MIO Bulkhead Cable Adapter to the 68-pin filler
panel using two M2.5 jacksocket screws that are provided with the
adapter.
5. Attach the 50-pin female connector of the ribbon cable to the 50-pin
accessory.
6. Attach the male connector of the ribbon cable to the 68M-50F MIO
Bulkhead Cable Adapter.
7. Secure blank filler panels in any remaining open slots using
two 4-40 ×3/16 in. flathead screws per filler panel.
Note When you connect a 50-pin external cable to a 50-pin CA-1000 accessory, you must
remove the 68-pin filler panel and the 68M-50F MIO Bulkhead Cable Adapter. This allows
you to attach the male end of the R50M-50F ribbon cable to the wall of the CA-1000
enclosure with two 4-40 ×3/16 in. screws.

I/O Panelettes
Use the user-configurable I/O panelettes to specify the type and
combinations of I/O connectivity for your application. The interchangeable
I/O panelettes have standard prewired I/O connectors. You can install
I/O panelettes on the front and/or rear of the CA-1000 enclosure.
You can install up to 18 single-width I/O panelettes, nine in the front and
nine in the rear, in the CA-1000 enclosure. You can mix all types of
I/O panelettes to produce custom I/O combinations.
Note The strain-relief and 9-pin D-sub I/O panelettes require two panelette spaces.
The dual 9-pin D-sub I/O panelette requires three panelette spaces.
Each thermocouple and BNC I/O panelette accommodates two connectors.
Use the strain-relief I/O panelettes to connect large numbers of wires
directly to your internal accessory. You can machine the blank
I/O panelettes to make custom I/O panelettes to suit your application.
Use the preconfigured I/O panelettes to quickly connect and disconnect
standard connectors.

4. Secure the I/O panelette with either one, two, or three of the
M2.5 ×6 panhead screws (depending on the type of I/O panelette)
that are included with the panelette.
5. Repeat steps 1 through 4 until you have installed all your functional
I/O panelettes.
6. Install a blank I/O panelette in any unused panelette opening.
Note You must remove the pre-installed rear panel prior to installing any I/O panelettes
on the rear of the CA-1000.
