8.155. VTXMODO -- Enable VTX Mode on Specified Inputs
Vortex devices can be connected to a Polycom VTX 1000 in order to use the wideband capabilities of
that device. When connecting to a VTX 1000, special proccessing is done on the Vortex in order to
guarantee compatibility with the VTX 1000. This command enables processing for the VTX 1000 on
the specified line output or outputs.
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.
