Polycom Vortex EF2280 User Manual

Using this command is more efficient than deleting one command or pin at a time since this command deletes
them all at once and requires fewer writes to non-volatile memory.
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.

F01LIK5
Delete all the commands associated with logic input pin 5. This one command is
equivalent to executing the commands 'F01LIA5, ', 'F01LID5, ', and
'F01LIH5, ' except that this command is more efficient.
F01LIK5
F01LIK*
Delete all the commands associated with all logic input pins. This one command is
equivalent to executing the commands 'F01LIA1, 'F01LID1, ', and 'F01LIH1, '
for each logic input, except that this command is much more efficient.

8.70. LIM -- Mask Logic Input Pins
This command is used to mask (i.e., disable) logic input pins. The mask consists of 24 fields (one for each logic
input) that can each be set to 0 or 1. If the mask bit for a given logic input is set to 1, then the logic input pin
works normally. If the mask bit for a given logic input is set to 0, then the logic input is disabled. When a logic
input is disabled, any commands assigned to the logic pin via
LIA, LID, and LIH will not be executed.
If a logic pin is disabled and then re-enabled at some later time and the logic input has changed state from when
it was disabled, the command associated with the state change will be executed. For example, if a logic input pin
is high when it is disabled, and it is low when it is re-enabled, the command defined via
LID (or LIA if the
polarity is changed via
LIP) will be executed. However, if the pin changes state multiple times while it is
disabled, multiple commands will not be executed; only the difference in state when the logic input is re-enabled
is considered.
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.

8.71. LIN -- Assign Command to Logic Input Group
This command assigns a command to be executed when a group of logic input pins is in a certain configuration.
Logic groups are defined via the
LIG command.
As an example, assume that the command F01LIG2,000001111100000000000000 has been sent to the
device. This command configures logic input pins 6-10 to be part of logic group 2. Now, we send the command
F01LIN2,10,MACROX25 . This command configures logic input group 2 to execute the command MACROX25
when logic inputs 7 and 9 are active ('1') and logic inputs 6, 8, and 10 are inactive ('0'). The first number in the
