The matrix expansion methods available for the different terminal blocks
are shown in Table 2-2.
The preferred expansion method is to connect columns using the matrix
expansion plug. You can use this plug to daisy-chain module columns
across an entire chassis, as shown in Figure 2-12.
Caution
Only daisy-chain terminal blocks of the same type together. Daisy-chaining
different types of terminal blocks together can cause damage to the module or to the
equipment connected to the module. For example, you can daisy-chain two or more
SCXI-1333 terminal blocks; however, do
not
daisy-chain the SCXI-1333 together with any
other type of terminal block.
