The Matrix Topology

A matrix is a flexible topology that can connect multiple inputs to multiple outputs organized as columns and rows. You can connect any column to any number of rows and any row to any number of columns. Refer to the NI Switches Help for more information about matrix topologies.

On a matrix schematic, row-column cross-points represent potential connections on the switch device. For visibility, the Switch SFP displays each connection and its associated connection route on the matrix schematic in a different color. For a channel with multiple connections, the Switch SFP displays all of the connections and their associated connection routes in the same color. Refer to row 0 (r0) of the schematic below for an example of a matrix channel with multiple connections.

Note  You can resize the Switch Device window to see more channels.

Refer to the schematic below for an example of the NI PXI-2532 in the 1-Wire 4×128 matrix topology.

Make a Matrix Connection

Click a row-column cross-point to make a connection on the matrix. To break a connection, simply click the connection again. The Switch SFP makes the appropriate connect/disconnect calls to the driver.
