Configuration Blocks
Configuration blocks allow access through pre-made molded cables to the rows
and columns of the matrix. Additionally, the rows can also be wired to 20-pin
expansion headers on the block.
Configuration block 34934C-001 is used with the 4x32, 4x64 and 4x128 matrices.
Configuration block 34934C-002 is used with the 8x32, 8x64 and 16x32 matrices.
The 34934C-001 is shown below.
The configuration block attaches to the 34934A module’s D-Sub connectors.
Matrix configuration (selection) is accomplished by placing jumpers on the
configuration block. You choose a configuration, place jumpers, then wire your
test circuit to the
configuration block’s
male D-Sub connectors and/or extension
headers. In addition, you will have to short two pins on each D-Sub to provide
safety interlock continuity.
All other configuration is done within the block; this
saves significant wiring time compared to direct wiring (which requires
user-supplied configuration jumper wiring between the 34934A’s D-Sub
connectors).
