A CD player can be remotely controlled via the bus using the "Media control, CD player" application.
The symbols for "On/Off", "CD selection", "Player control" and "Volume" are shown first on the display. Via the push-
button/rotary control element, the user can access a submenu ("CD selection", "Player control" and "Volume") or can switch
directly on or off via a push-button operation.
In the submenu "Player control" the symbols for Start, Stop, Forward etc. are shown on the display. By turning the push-
button/rotary control element, the user can select the desired function (focus) and trigger it with a push-button operation. The
"CD selection" submenu functions in a similar way.
If the volume is to be regulated, a special volume symbol is shown on the display which signals the user that: a turn to the
right increases the volume and a turn to the left reduces the volume. A feedback signal from the connected actuator can not
be shown here.
Depending on the function, telegrams to the CD player control are sent out on the communication objects for "CD on/off",
"CD selection", "CD play", "CD stop", "CD pause", "CD previous track", "CD next track", "CD volume".
In addition, the function can be temporarily blocked via an additional 1-bit "Enable" communication object.
Hint:
The function is practical only if a corresponding additional unit, such as the media box made by Coldwey, for CD player
activation is used as receiver of the sent out telegrams.
