3.3 TB-6231 Terminal Board
Configurations
The TB-6231 is a screw terminal board with D-sub 62-pin female connector. 
The terminal board can attach to PXI-7931 directly, or through ADLINK’s 
custom-made high-capacity 62-pin D-sub cable. 
 
Users can use the TB-6231 terminal board to make various matrix 
configurations. The TB-6231’s default configuration is a 4-group 2x4 matrix 
in 2-wire. If other matrix configurations are preferred, users can refer the 
table below to short the relative pads. 
For example, to use a 2x4 matrix, do not short any pads. To use 2x16 matrix, 
short the last 12 pads at the lower-right corner of the table. 
2x4 Matrix
This configuration has four independent 2x4 matrices, Bank0 to Bank3, each 
with two rows and four columns. The following diagram illustrates the PXI-
7931 with the TB-6231.
