The controller PCB switches are listed in Table 1-3 . SW4 is a toggle switch for PROJ_ON which is used to turn
on and off the electronics. Note that parts of the board are still powered when PROJ_ON is in the off position.
SW1, SW2 and SW3 are dip switches that control the states of configuration signals the DLPC230-Q1 reads
when it comes out of reset. These switches must be set based on the desired configuration options.
