Polycom Vortex EF2211 User Manual

ERROR#092
This error indicates an EF Bus ID conflict. See the Vortex user manual for
information on valid device IDs.
ERROR#093
This error indicates an EF Bus reference conflict. This error occurs when more than
one Vortex is placing its AEC reference on the bus. Use the
BUSREF command to
remove the extra reference(s) in order to resolve the conflict.
This command is a boolean command. See
Section 6.1 for more information on this type of 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.

8.47. FADERGIL -- Set Fader Gain of Line Inputs as a
Group
This command sets the fader gains of all the line inputs simultaneously. This is different from using a
wildcard, * with the
FADERI command because that command sets all the mic and line inputs
together, while the FADERGIL sets only the line inputs.
This command will generate acknowledgements from each of the line inputs separately.
This command is an integer command. See Section 6.2 for more information on this type of
command. The minimum and maximum values for this command are -100 and 20, respectively.
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.
Example Description Status Message
S01FADERGIL7
Set fader gain of all line inputs to 7
dB.
