Matrix 2
NOTE: Although columns are numbered
the same on the two matrices, they are
electrically separate.
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
