Linking Multiple Matrix Modules
You can link multiple matrix modules to form a larger matrix. The drawings on
show examples of two-module connections through rows and columns.
Wiring Multiple 34931A or 34932A Modules
With a 34931A you can combine two matrices to form 8x8 (connecting columns)
or 4x16 (connecting rows) configurations. Using two 34932A matrices on a
34932A module, you can create 16x8 (connecting columns) or 4x32 (connecting
rows) configurations.
You can connect rows in separate modules using external wiring. Or, using Bank 2
matrices, you can connect through the mainframe Analog Buses. For a clear idea
of how matrices are arranged and their connections to the Analog Buses, see the
simplified schematics on
(34931A) and
(34932A).
You must use external wiring whenever you connect:
– Rows in Matrix 1 of separate modules
– Rows in Matrix 1 to rows in Matrix 2 on the same or separate modules
– Columns of two matrices on the same or separate modules
You can expand upon these two-module configurations and add up to eight
modules to design your own large matrices. From a programming standpoint,
each matrix module operates as an independent module regardless of the
external connections. When linking modules, the channel numbering scheme
remains the same as for single modules.
Wiring Multiple 34933A Modules
You can connect matrices on the 34933A module in a similar fashion to the
34931A. However, the presence of in-rush resistors on the Analog Buses and
columns require additional consideration, and you must take care when linking
multiple 34933A matrix modules. See the simplified schematics on
