Li -- Query State Of Logic Inputs; Lia -- Assign Action For When Logic Input Is Activated - Polycom Vortex EF2241 Programming Manual

minimum and maximum values for this command are 1 and 4, respectively.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.

8.78. LI -- Query State of Logic Inputs

This command returns the current state of the logic inputs. There are 24 logic inputs, so an array of 24
boolean values is returned with the first value indicating the state of the first logic input, the second value
indicating the state of the second logic input, and so on.
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each
time it is changed. It will retain its value after power-down. Since this command writes to non-volatile
memory, there will be a delay before an acknowledgment is returned.

8.79. LIA -- Assign Action for when Logic Input is Activated

This function assigns a single command to be executed when a given logic input changes from the inactive
state to the active state. Typically, the inactive state is logic high ('1') and the active state is logic low ('0').
This is commonly referred to as active low. Acitve low is considered normal because a closed switch would
ground the input and a closed switch would normally be considered active. This polarity setting can be
changed via the command.
LIP
A single command can be assigned to each of three conditions occurring on the logic pin: a change to the
active state, a change to the inactive state, and a repeating command when the pin is held in the active
state. The LIA command assigns a single command to the logic pin that is executed when the logic pin
changes to the active state.
Although only one command can be assigned to the state change, the command may be a
command. Since up to 256 commands can be stored in each macro, this gives the effect of having
