MACROQ command. Since up to 256 commands can be stored in each macro, this gives the effect of
having up to 256 commands execute when the logic pin changes state. The command associated with
the state change can also be a
PRESETX or PRESETQ. This makes it easy to reconfigure the device for
different rooms based on external logic settings.
The
BROADA is also useful in logic pin assignments. The BROADA command transmits a command to
another device on the EF Bus, so you can effectively make a logic pin state change on one device
cause an action to occur on another device.
ERROR#074 will be generated if the assigned command is one that writes non-volatile memory, and
the pin will not actually be assigned.
See the description of the
LIA for examples on how to use the LIH command. The syntax for this
command is exactly the same. One additional example is given here: using the LIH command for
volume control.
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.
Example Description Status Message
S01LIH8,GAINIA>3
Assign the command GAINIA>3 to occur repeatedly
when logic pin 8 is held in the active state. The
GAINIA>3 command causes the gain on input channel
A to increase by 3 dB each time the command is
executed.
S01LIH8,GAINIA>3
8.79. LIEN -- Enable Automatic Logic Input Status
Messages
This command controls whether or not logic input status messages are sent automatically. If LIEN is
enabled, then a logic input query (LI*?) is performed any time any of the states change on the logic
input pins. For example, if all logic inputs are currently in the low state ('0') and LIEN is enabled, then
if logic input 12 changes state to '1', the following status message will be generated:
S01LI*000000000001000000000000
A status message is only generated if there is a state change. This helps keep data traffic to a
minimum.
This command is a boolean command. See
Section 6.1 for more information on this type of command.
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.
