Placing Row Access Jumpers on the 34934C-001 Configuration Block
The
jumpers in 3x16 jumper block J8 (at lower board center) determine if row
connections can be made from the two male D-Sub connectors P1 and P2 (i.e.
they “enable” the row signal connection points at the D-subs).
These “row connections” are the traditional access points from field wiring to the
matrix rows. In practice, your arrangement of test instrumentation and DUT test
points will determine if you wish to make row connections at the D-subs, at the
blue 20-pin connectors, or both.
Setting these jumpers provides you the flexibility to plan how to route your custom
cabling.
The following illustration shows the jumper block J8, along with the relevant
guidance provided on the board’s silk-screen for jumper placement:
If you plan to extend rows

,
to J5 and J6, place two
2x8 jumpers as shown at right.
The row signals will also be
present on J6

you placed the optional
CONFIG jumpers in step 3 on
