Creating Larger Matrixes with Multiple Mainframes
You can create larger matrixes with the matrix modules by using the
E1466-80002 Daisy Chain Expansion cable. With larger matrixes, more
crosspoints become available. A C-Size mainframe can have up to 3,072
two-wire crosspoints. You can make a larger matrix by connecting the rows
or columns of one terminal module to the corresponding rows or columns of
the next terminal module. Only the E1465A has a column expansion. You
can also create larger matrixes by connecting multiple mainframes together.
When using multiple modules, the modules should be configured as a
switchbox. That is, the first switch card (module) has a logical address that
is a multiple of 8 and succeeding switch cards have sequential logical
addresses. For example, if you use the matrix default address of 120 for the
first card, the remaining cards in the switchbox would have logical addresses
of 121, 122, 123, etc.
When using multiple modules configured as a switchbox, you must address
the modules as a switchbox. For example, if you want to close row 00,
column 05 on the second card, use CLOSe @20005).
Figure 2-11 shows how to connect four E1465A 16x16 modules to create a
32-row by 32-column matrix. This configuration requires 16 E1466-80002
Daisy Chain Expansion cables. The daisy chain rows of modules 1 and 3
are connected to the rows of cards 2 and 4 to increase the number of
columns.
The daisy chain columns of cards 1 and 3 are connected together and the
daisy chain columns of cards 2 and 4 are connected together. For example,
to connect row 16 to column 15 use CLOSe (@30015). This command will
close the relay on card 3, row 00, column 15. The following table shows
which cards support applicable rows and columns.
