Polycom Vortex EF2280 User Manual

Logic output 10 will be deactivated if:
● (input 1, input 2, input A, and input B are unmuted) AND
● (input C OR input D is muted)
An error condition of ERROR#074 will be generated if the assigned command is invalid.
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
F01LOA10,MUTEI*1100++--....
Configure the conditions for
activation of logic output 10 as
described in the example above.
F01LOA10,MUTEI*1100++--....
F01LOA7,
Delete conditions for activation of
logic output 7.
F01LOA7,
8.75. LOD -- Define Behavior for Logic Output Deactivated Status
This command is used to define the conditions under which a given logic output pin goes into the deactive state.
The syntax and behavior of this command is identical to that of the
LOA command. Please refer to the
description of the
LOA command for more information, including examples.
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.
8.76. LOEN -- Enable Automatic Logic Output Status Messages
This command controls whether or not logic output status messages are sent automatically. If LOEN is enabled,
then a logic output query (LO*?) is performed any time any of the states change on the logic output pins. For
example, if all logic outputs are currently in the low state ('0') and LOEN is enabled, then if logic output 12
changes state to '1', the following status message will be generated:
F01LO*00000000000100000000
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.
Example Description Status Message
F01LOEN1
Enable automatic logic output status messages.
F01LOEN1
F01LOEN0
Disable automatic logic output status messages.
F01LOEN0
F01LOEN2
Toggle automatic logic output status messages.
F01LOENx , where x is 0 or 1 depending on the
current setting of LOEN.
