You can use existing external controls that you've created in the External Controls dialog, or you can create
new controls in the Control Page Designer dialog. No matter where you create them, once they are present
you can link them to other controls in your configuration and add them to one or more control pages. This
approach allows for great flexibility in what you provide to your end users for controlling the system,
whether it be only web pages or a combination of web pages, DR6 devices, other Digital Remote devices,
and external control systems (such as AMX or Crestron).
How do controls on a control page relate to the other controls in my configuration?
Once you have created controls in the External Controls dialog or in the Control Page Designer dialog,
you can then link them to any other linkable control of the same type in your HAL configuration. The proc-
ess is the same as how you link controls together in other parts of the Halogen software, which is fully
explained in Creating a Control Link. For external controls, the link icon appears in the Control Page
Designer palette as well as the External Controls dialog and the property dialog for the control.
For example, you can create a link for a control system toggle by dragging the link icon from a toggle in the
Control Page Designer palette and dropping it on a Line Output Mute toggle link icon as shown here:
How do I add controls to a control page?
After you've linked a control in the Control Page Designer palette to another control, you can then include
that control on a control page by dragging the control from the palette and dropping it on the page layout
area like this:
1
Has no state. A Command control simply allows you to initiate an action. Unlike a Toggle, you cannot undo a
Command. The most common usage of Command controls is to assert a preset.
2
Generally associated with volume, Level controls have a continuous series of states that are represented by a
slider.
3
Allows the user to switch between two states — on or off. A common usage of a Toggle control is to mute/un-
mute audio. Another common usage is to activate/deactivate a preset.
4
Allows the end user to make a selection from a list. Uses for a Selector control might include selecting a music
channel, a preset, a room combination, and so on.
