Lia -- Assign Action For When Logic Input Is Activated - Polycom Vortex EF2211 Programming Manual

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.

8.76. 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
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
