Many BrightSign models feature a DA15 or Phoenix-style GPIO port for device communication and interactive input/output. Select Input or Output for each GPIO button to indicate whether it should be used to receive or send information.
Note
The "button" numbers described here are not the same as GPIO "pin" numbers: Some pins act as power supply or ground, so they are not included in the button numbering scheme. See the hardware manual associated with your player model to view a mapping of buttons to pins.
