Placing CONFIG Jumpers for 8x32
The CONFIG jumper area—shown below
with jumpers removed— includes an illustration below it on the silk-screen that
shows jumper placement for setting a 8x32 matrix configuration.
There are two 4x2 blocks of CONFIG JUMPER pins on each side of the board’s
center—you must set all four blocks identically.
1 Place sixteen horizontally positioned jumpers as shown below.
Placing ID Jumpers for 8x32
The ID jumpers allow the 34980A to recognize
the 8x32 matrix configuration upon mainframe bootup. Jumper placement
guidance is provided on the silk-screen (below left); the ID jumper block is shown
at right with jumpers removed.
In a high temperature-high humidity environment, salt and oil contaminants
transferred from the fingertips to the moveable CONFIG jumpers can affect the
34934A’s published DC Isolation specification if adjacent jumpers are in physical
contact with each other. In applications where DC (channel to channel) isolation >
10 GΩ is required, use clean cotton gloves when handling the CONFIG jumpers.
If cotton gloves are not available, clean the plastic jumper surfaces using a
cotton cloth and 91% isoprolyl alcohol after handling.
