The Controller PCB switches are listed in Table 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 should be set based on the desired
configuration options.
