columns. To expand the columns of a matrix, complete the following steps:
1.
Connect one end of the matrix expansion cable to one of the ROW
CONNECTION CABLE terminals in one of the SCXI-1379 terminal
blocks.
2.
Connect the other end of the matrix expansion cable to one of the ROW
CONNECTION CABLE TERMINALS in another SCXI-1379.
3.
Connect the two SCXI-1379 terminal blocks to the front connectors of
the two SCXI-1130 modules.
4.
Tighten the top and bottom chassis screws on the back of the terminal
block rear panels to hold them securely in place.
