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
B01LIH8,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.
B01LIH8,GAINIA>3
8.82. 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:
B01LI*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.
