When the external triggering signals are rising from low values, PIN-16 (i.e. RI 1) generates a rising edge, which will cause
the sound mixing function of the contact corresponding to the sound mixer to be turned on.
C. Basic Attribute of GPIO Input Channel RI
a) GPIO Channel: display the number of the input channel being set currently.
b) GPIO Enabled: set the parameters of the channel at On state.
c) Display Type includes Scene Setting, Mixer Setting, Volume Setting, Channel Mute Setting, Mute System and Serial
Command Setting.
Control type has 2 basic attributes:
1) Trigger Mode: categories of trigger types depend on control types, and there are at most 4 triggering modes (Rising
Edge Trigger; Falling Edge Trigger; Rising Edge Selection and Falling Edge Trigger Cancellation; and Falling Edge
Selection And Rising Edge Cancellation); and Rising Edge refers to the fact that electrical level of the GPIO input
channel pins is changed from low to high; and Falling Edge refers to the fact that the level of the GPIO input channel
pins is changed from high to low.
2) Parameter Setting: parameter setting depends on control types, and different control types allow different parameter
settings.
