Polycom Vortex EF2280 User Manual

changes to the system via the front panel. The system settings will still be viewable on the LCD, but the user will
get an error message if he tries to change them. When FPLOCK is disabled, the user has full access to the
system settings via the front panel.
Usage of this command is similar to other boolean commands (see
Section 6.1) except that when disabling this
feature, the password must be supplied for the command to work. If an incorrect password is supplied,
'ERROR#005' will be generated. The examples below illustrate the correct usage. The examples assume that the
password has been set to 'aspi' (the default). The front panel password can be changed via the
FPPSWD
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.
Example Description Status Message
F01FPLOCK1
Lock the front panel to prevent users
from changing the settings.
F01FPLOCK1
F01FPLOCK0,yumyum
Attempt to unlock the front panel by
using an invalid password (yumyum).
F01ERROR#005 -- since an invalid password
was given, an error message was generated. If
error messages have been disabled (via the
ERROR command), then no status message will
be generated.
F01FPLOCK0,aspi
Unlock the front panel by using the
correct password.
F01FPLOCK0
F01FPLOCK?
Query the locked status of the front
panel.
F01FPLOCKx , where x is 0 or 1 depending on
whether the front panel is unlocked or locked,
respectively.
8.47. FPPSWD -- Change Front Panel Password
This command sets or queries the front panel password. This password is used in conjunction with the FPLOCK
command. The front panel must be unlocked ('FPLOCK0') in order to use this command to set or query the front
panel password. If the front panel is locked, then this command will result in 'ERROR#004'. The examples below
assume that the front panel is unlocked.
Example Description Status Message
F01FPPSWDmonkey
Set front panel password to 'monkey'.
F01FPPSWDmonkey
F01FPPSWD?
Query the current front panel password.
F01FPPSWDmonkey
8.48. GAINGIL -- Set Gain of Line Inputs as a Group
This command sets the gains of all the line inputs simultaneously. This is different from using a wildcard, * with
the
GAINI command because that command sets all the mic and line inputs together, while the GAINGIL 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
