Creating Expanded-Row Matrices Using Configuration Blocks
Four-row matrices use the 34934C-001 configuration block. Eight-row or
sixteen-row matrices use the 34934C-002 configuration block.
Your large matrix will be built as multiples of a base configuration of 4x32, 4x64,
4x128, 8x32, 8x64 or 16x32. Thus, please thoroughly read the appropriate base
Chapter 2, “Base Matrix Configuration”
, before combining
modules and these configuration blocks to create multiples of your base matrix.
In
, you placed jumpers on each configuration block which determined
which expansion headers are available for module interconnection
.
The illustration below shows expansion header locations on the 34934C-001
configuration block; the expansion header layout for the 34934C-002 is the same.
The next section shows how to make connections linking the modules through the
expansion headers.
Interconnecting Configuration Blocks
At each side of each configuration block are a pair of 20-pin extension headers.
On the right side are labeled J3 and J4; on the left side are J5 and J6. These
headers provide for row extension and row signal access, depending on the
