Matrix card notation
To specify channels using matrix card notation, use SBRCC, where:
S Slot
number
B Bank
R Row
number*
Some cards use a range of 1 to 4 or 1 to 8; other cards use a range of A to P (refer to the card's documentation)
CC
Column number (always use 2 digits)
For columns greater than 99, use A0 for column 100, A1 for column 101, A2 for column 102, and so on, through A9 for
column 109. Use B0 for column 110, B1 for column 111, and B2 for column 112.
*All Model 3732 configurations use numbers for the rows except the single 16x28 configuration, which uses numbers and the
letters A and B for the rows.
