Polycom Vortex EF2280 User Manual

input and a closed switch would normally be considered active. This polarity setting can be changed via the LIP
command.
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
MACROX or 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.
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
F01LIA4,MUTEI11
Assign the command
MUTEI11 to occur when logic
input pin 4 changes from the
inactive to active state. The
MUTEI11 mutes input channel
1
F01LIA4,MUTEI11
F01LIA5,MACROX23
Assign the command
MACROX23 to occur when
logic input pin 5 changes from
the inactive state to the active
state. The MACROX23
command executes macro 23,
which can contain up to 256
other commands.
F01LIA5,MACROX23
F01LIA6,BROADA:F02MUTEI11
Assign the command
BROADA:F02MUTEI11 to
occur when logic input pin 6
changes from the inactive
state to the active state. This
command causes the EF2280
at ID 2 to mute its input
channel 1 when logic pin 6 on
the EF2280 at ID 1 changes
from the inactive to active
state.
