Daisy-chaining matrix rows
In order to route one or more external sources to other matrix modules, the rows of the modules must be daisy-chained.
External cabling is used to connect the rows of the matrix modules together.
shows examples of row daisy-chained matrix systems. For the 6
×
16 matrix, daisy-chaining the two matrix modules
allows the external source to be routed to the second module. For the 6
×
40 matrix, daisy-chaining the five matrix modules
allows the external source to be routed to any of the 40 columns in the system.
NOTE
Techniques to daisy-chain rows are explained in “

Notes:
The matrices in this illustration are simplified to show external source
connections to other matrix modules. Connections to the DMM are
not shown.
Each signal path shown in this illustration is actually a two conductor
path pair (HI and LO).
