3.2.1. Si1120 EVB Header J1 Settings
To function properly with the demonstration firmware, the shorting blocks on header J1 should be set as indicated
in Figure 1. However, these can be set differently, according to the application. The corner emitter is fixed at D1,
but a shorting block point is provided for debug purposes. The “X” and “Y” axis emitters can each be moved
between three different positions on the board, as shown in Figure 4.
