To link controls together, the participating controls must be of the same type: Level control, Selector control, Toggle control, or Command control. Linking one control to another is a very simple process. Linking three or more controls is also a simple process, but requires a bit more understanding of control linking concepts. For conceptual details, see About Control Links.
note: In certain situations, the link confirmation dialog box may contain up to two more choices: Add to Link and Remove from Link. This happens only if the source and/or target control is already participating in another link.
best practice: In most cases, it is best to drag your controls from the Control palette onto the controls in the Processing Map. Therefore, your control link target will most often be a control on your Processing Map.
Let's say you are linking two DR1 devices to a Level block Gain control. Given the best practice outlined above, we'll choose the Level block control as our target.
Instead of dropping link icons from multiple controls directly onto another control, you can open the All Links dialog box, create a control link, and drag and drop each control onto the link. Think of the control link in the dialog box as a bucket into which you will be dropping participating controls. The following procedure outlines the steps:
tip: To verify that the link now contains all the intended participants, you can open the link and view its contents.
