Using the SCXI-1129
This chapter discusses the operation of the SCXI-1129. The SCXI-1129 is
a relay switching matrix.
Operating as a Matrix
A matrix is one of the most flexible switching configurations. Unlike a
multiplexer, a matrix can connect multiple inputs to multiple outputs. A
multiplexer is typically organized into channels and commons, while a
matrix is organized into columns and rows. You can connect any column
to any number of rows and any row to any number of columns. At each
intersection of a row and column, there is a switch. When the switch is
closed, the row is connected to the column. The SCXI-1129 is a 2-wire
matrix, as shown in Figure 2-1. Matrixes are useful in applications where
you desire maximum switching flexibility.
