NOTE: Although rows are numbered the same
across the matrices, they are electrically
separate.
NOTE: Three-digit channel
numbers are derived from a
specific matrix number and the
intersection of rows and
columns on that matrix. The
channel shown here is 132
(Matrix 1, Row 3, Column 2.)
Channel 2128
(Matrix 2, Row 1, Column 8)
