• By default, shunts connect the columns marked “FlexGUI CNTL (JUMPER)”. This
connects the onboard microcontroller to the control port of the CS53L30.
• To use external control signals, remove shunts and connect the external controls to the
columns marked “EXT SYS (CABLE)”. Notice the ground connections on Column 3.
