SCXI-1181K Custom Module Assembly
This guide documents the contents of your SCXI-1181K custom module assembly kit and
includes illustrations of the circuit board specifications and the module assembly.
Introduction
The SCXI-1181K custom module assembly kit includes the unassembled components you need
to build a custom SCXI module, but not the actual circuit board. All of the mechanical
components of an SCXI module, such as the metal enclosure, front and back panels, and
connectors, are included.
The SCXI-1181K is intended for developers of custom SCXI modules who design and lay out
custom circuit boards for modules. For prototyping or building low-volume custom SCXI
modules, the fully assembled SCXI-1181 breadboard moduleis more appropriate.
What Your Kit Should Contain
The SCXI-1181K custom module assembly kit (part number 776572-81K) contains the
components listed in the following table. The reference numbers in the left column of the table
refer to callouts in Figure 1.

Refer to the reference numbers of the components in the previous table and the corresponding
components in Figure 1 for module assembly.
Note: The four P1 connectors have a push-fit peg. Secure the P1 connectors to the printed
wire circuit board (PWB) by pushing the connector onto the PWB so that the middle
peg of the connector presses into the 0.081 in. hole in the PWB. National Instruments
recommends using the push-fit peg hand tool (part number CTHT-200) manufactured
by ITT Cannon for this installation. You can contact ITT Cannon at [phone].
