Switch Control

U2751A User's and Service Guide
A matrix switch connects multiple inputs to multiple
outputs. A matrix is arranged in rows and columns. For
example, the U2751A is a 4×8 matrix that can be used to
connect four sources to eight test points as shown in
Figure 2- 1.
Any column can be connected to any row by activating the
corresponding relay that connects the column to the row as
shown in Figure 2-
has its own unique channel label representing the row and
column. For example, channel 302 represents the cross-point
connection between row 3 and column 2.
Be aware that it is possible to connect more than one source
to the same point with a matrix. It is vital to make sure that
these connections do not create dangerous or unwanted
conditions.

Note: Three-digit channel numbers are derived from
the intersection of the rows and columns, with the
last two digits representing the columns. The
