n2 is the current selection. The selection range is [1, 8].
n3 is the current command state. The command state
represents the state of the encoder.
The possible states follow:
0 No Operation The encoder has not changed.
1 Encoder Left The encoder has been turned counter clockwise.
2 Encoder Right The encoder has been turned clockwise
16 Selection Left The encoder has been pushed in and turned counter clockwise.
32 Selection Right The encoder has been pushed in and turned clockwise.
64 Enter The encoder has been pushed in and released without being turned.
n4 is the length of time the encoder button has been pressed. The time the
button has been pressed is in units of .01 seconds and the range is [0, 255]
or 0 to 2.55 seconds. The button timer starts at the press of the button and
is reset to zero when the button is released.
Example: 3,5,0,0,"OK" means the current level is 3, the
current selection is 5, the current command state byte is a No
Operation and the button is not pushed in. This means the level
and selection were updated. A response of 3,7,32,100,"OK" means
the current level was updated to 3, the current selection is 7 and
was last changed by someone pushing in and turning the encoder,
the current command state byte is a Selection Right, and a non-
zero button time means someone is still holding the button in.
IF
Input Force
Forces new level and selection. Resets the command state to No Operation.
The level is updated and indicated by the encoder LED regardless of Auto Level
configuration.
The selection is updated and indicated by the column of LEDs regardless of Auto
Selection configuration.
Send: IF,n1,n2
Where: n1 is the new level. The level range is [0, 31]. If n1 is
zero, the level remains unchanged.
n2 is the new selection. The selection range is [0, 8].
If n2 is zero, the selection remains unchanged.
Example: IF,3,5 sets a new level of 3 and a new selection of 5.
Response: "OK"
