Single-Board Configuration
The AMUX-64T is shipped from the factory with U12 set for single-board
configuration as shown in Table 2-5.
Two-Board Configuration
For the two-board single-ended configuration, assign one board channel
addresses from 0 to 63, and assign the other board channel addresses from
64 to 127. For differential operation, assign one board channel addresses
0 through 31 and assign the other board channel addresses 32 through 63.
The board that you assign addresses 0 through 63 (or 0 through 31) is
referred to as board A, and the board that you assign addresses 64 through
127 (or 32 through 63) is referred to as board B. You can configure any
board as board A or board B, as shown in Table 2-7.
The switch settings for board A and board B in a two-board configuration
are shown in Table 2-5.
Four-Board Configuration
For the four-board configuration, each board has a different switch setting.
You assign the first board channel addresses from 0 to 63, the second board
channel addresses from 64 to 127, the third board channel addresses from
128 to 191, and the fourth board channel addresses from 192 to 255. For
differential operation, assign the first board channel addresses 0 through
31, the second board channel addresses 32 through 63, the third board
channel addresses 64 through 95, and the fourth board channel addresses
96 through 127. The board that you assign addresses 0 through 63
(or 0 through 31) is referred to as board A; the board that you assign
addresses 64 through 127 (or 32 through 63) is referred to as board B; the
board that you assign addresses 128 to 191 (or 64 through 95) is referred
to as board C; and the board that you assign addresses 192 through 255
(or 96 through 127) is referred to as board D. You can configure any board
as board A, board B, board C, or board D, as shown in Table 2-8.
