Polycom Vortex EF2280 User Manual

The first argument in the command specifies the automixer number (1-2) and the second argument specifies
whether automixer reference mode should be enabled, disabled, toggled, or queried.
Even though this is a channel boolean command, use of the wildcard character for the automixer number is not
supported.
This command is a channel boolean command. See
Section 6.3 and 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.
Example Description Status Message
F01AMREFE10
Disable automixer reference mode for
Automixer 1.
F01AMREFE10
F01AMREFE21
Enable automixer reference mode for
Automixer 2 .
F01AMREFE21
F01AMREFE2?
Query current setting of automixer
reference mode for Automixer 2 .
F01AMREFE2x , where x is 0 or 1 depending on
the current setting of automixer reference mode
for Automixer 2 .
8.27. BAUD -- Set Baud Rate for RS-232 Port
This command sets the baud rate for the rear panel RS-232 port. The baud rate is specified in bits per second
(bps). Valid baud rates are 9600, 19200, and 38400. Although, this command returns an acknowledgement, it is
likely that you will not receive it, since it is sent at the new baud rate. If you setup your control system to quickly
change its RS-232 baud rate after you send this command, then you can probably receive the acknowledgement
at the new baud rate.
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
F01BAUD38400
Set baud rate of rear panel RS-232 port
to 38400 bps.
F01BAUD38400
F01BAUD?
Query current baud rate of rear panel RS-
232 port.
F01BAUDx , where x is 9600, 19200, or 38400
depending on the current baud rate setting.
8.28. BLAUTO -- Enable Automatic BLDATA Messages
This command sets whether or not BLDATA messages are automatically generated by the Vortex. See the
BLDATA command for more information.
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.
