Defining External Volume Commands
When using external volume control you must configure RS-232 commands to send
to the TV when changing volume. Volume commands do not need to be configured
when internal volume control is used.
to the TV when changing volume. Volume commands do not need to be configured
when internal volume control is used.
StadiumVision Director allows you to define volume controls that are relative
(volume up and volume down) or absolute (volume number). Relative volume
commands depend on the volume increments set in the TV, which may vary widely

controls.

Absolute Volume Commands
To define absolute volume controls for the attached TV, you must first define the
desired number of increments (levels) between minimum and maximum volume. If
you do not define this then the system default of 10 levels will be used. Once
completed proceed to define the RS-232 command for each volume level.
