NOTE: Matrix 1 and Matrix 2 are
electrically separate from one another.
NOTE: Three-digit channel numbers are
derived from the intersection of the rows and
columns, columns having two digits. The
intersection shown here represents Channel
315 (Row 3, Column 15).
NOTE:
Matrix Relays: Armature latching
Analog Bus Relays: Armature non-latching
