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 308 (Row 3, Column 8).

Matrix 2

NOTE:

Matrix Relays: Reed non-latching

Analog Bus relays: Armature non-latching

NOTE: Although columns are numbered the same on Matrix 1 and Matrix 2, they are electrically separate from one another.

NOTE: All series resistors shown are 100Ω.
