NI SCXI-1379 Installation Instructions
❑
Matrix expansion cable (to expand the columns of a matrix)
❑
Matrix expansion plug (to expand the rows of a matrix)
Tip
NI recommends using 28 AWG wire (ribbon or discrete) for use with the SCXI-1379
terminal block.
3. Connect Signals
To connect signals to the terminal block, refer to Figures 1 and 2 while
completing the following steps:
1.
Prepare the signal wire by stripping the insulation no more than 7 mm.
2.
Remove the top cover screw.
3.
Unsnap and remove the top cover.
4.
Loosen the two strain-relief screws on the strain-relief assembly.
5.
Run the signal wires through the strain-relief opening.
6.
Insert the stripped end of the wire fully into the terminal. Secure the
wire by tightening the screw of the terminal. No bare wire should
extend past the screw terminal. Exposed wire increases the risk of
a short-circuit induced failure.
Note
When connecting signals to the SCXI-1379, refer to Table 1 to determine where to
connect signals for the 8x32, 1-wire matrix topology.
7.
Tighten the two screws on the strain-relief assembly to secure the
cables.
8.
Reinstall the top cover.
9.
Replace the top cover screw.
