Daisy-Chaining Multiple AMUX-64T Boards
Table 2-6 lists the valid multiple-board configurations for both
single-ended and differential modes.
When you connect two or more AMUX-64T boards together, the
multiplexers on different boards must be enabled at different times.
Therefore, each board is assigned a different channel address range
determined by the configuration of switch U12. The switch settings for
each board configuration are given in the following sections.
Table 2-6.
