8.68. LIG -- Configure Logic Input Pins Into a Group
This conmmand configures which logic input pins are in a group. Logic groups allow events to happen when
certain combinations of inputs are present on the logic pins. For example, if a logic group was defined that
consisted of three logic input pins (pin 1, pin 2, and pin 3), then a total of eight combinations (2
3
) are possible,
and a command or macro can be assigned to each combination. This feature is particularly useful in room-
combining applications. It can also be used to make controls based on rotary switches that output binary, BCD,
or Gray codes.
Commands can be assigned to the configurations of a logic group via the
LIN command.
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.

8.69. LIK -- Delete One or All Logic Input Pin Commands
This command "kills" or deletes all commands for a given logic input pin. In other words, the commands
associated with
LIA, LID, and LIH will be deleted for the specified logic input. A wildcard character can also be
specified for the logic input pin, in which case the commands for all logic input pins will be deleted.
